Mr Pete is awesome, the amount of knowledge he holds is amazing, I'm glad he making these video so it won't be lost to time
I am no smarter than the average bear
@@mrpete222 lol
Thank you Mr Pete. I wish I had the time to spend with a good friend of mine who was a first class machinist. Interestingly at work he operated a very big lathe most of the time, yet he was also expected to operate any machine in the shop of course. In his home shop he did anything and everything. It was always a joy to visit him. He loved making steam boilers (up to 6 inch) steam models, radio controlled aeroplanes, he repaired musical instruments. And I thought it was always funny that he could buy steam valves for his steam models but he would make them from scratch. You remind me so much of him.
Good story, he must be quite a guy
I have been eagerly awaiting the "next" video in hopes of seeing how to sharpen end mills as described in VEVOR's advertisement. After watching your video this morning I was extremely disappointed in finding out the sharpener fell short of this application. I think VEVOR should compensate the buyers of this unit in some fashion. As for the sharpening of the drills, I am very pleased. I purchased the unit for the very reason it was stated it would sharpen both drills and end mills.
Agreed
I just came from the Vevor web page for this product and yes, right there in the tool description at the top of the page it says it will sharpen end mills. Down in the comments someone asked how that was done and the response was it cannot sharpen end mills. Since I don't reward click bait advertisers I'll keep my Drill Doctor which works very well for me and wait for another vendor to come up with a home shop class effective end mill grinder.
Vevor will be offering disappointed buyers an all expense paid 2 week vacation to North Korea, please stay tuned.
I bought the model B. I could not remove one of the two small pins on the web thinning/point splitting hole even using pliers. The pin had obviously been hammered in since its top was peened over. After some time, Vevor customer service recommended removing it with tweezers! I finally removed by heating with a small torch and using vise grips to pull it out. Very difficult. The supplied pins are soft steel and I’m sure the difficult one was bent and pounded in. I replaced them with polished 3mm hard stainless pins that I made my self. Suggesting tweezers was ridiculous. The tool does work very well but I hope I don’t have to contact customer service again.
Sorry to hear that, but I’m glad you got it fixed
Thanks chap very informative will certainly watch the next installment!
Morning Lyle.
Bought mine when you introduced me to #1
👍👍
In all videos about this machine I have never seen a demo of what the rear knob on 13B does and how to do it. Can you show?
Neat! I have an index of super cheap, super sharp HSS bits that seem to be so quickly sharpened at the factory they usually cut on one side only.
Another useful consideration if pondering a powered sharpener. Thank ya sir!
I really enjoyed this video. I'd buy one if I didn't have so many not-so-much-used drills. Any bad ones could be pitched as plenty more good ones are on hand.
Bottom lime is this: If I had a need, I'd buy one. But Pete: here's a different twist on presentation: I learned and mastered drill sharpening in vocational machine shop. Could I do it now as good as I did when age 18? Probably not at age 72. So for older folks that are still active in shop work the Vevor looks really good. For those like me, my money doesn't go very far like it did four years ago, so I don't think I can afford one seeing as I may not have a real need. If Vevor gifted me one, I'd jump at dressing up all the worn drills in my shop.
👍👍👍
I bought one about a year and a half ago and really like it. Love your videos on them, and I hope you can explain in the next video what the knob on the top is for. could find nothing in the instructions on it. Thanks
I think that one of these Vevor drill sharpeners will be what my next bonus check at work will going to.
👍👍👍
Mr Pete, I did what I was not supposed to do, and I adjusted the split point knob and set screw and sure enough, I’m having issues. Go figure lol. Would you mind measuring the clearance between the adjusting arm? I’m trying to reset the arm back to factory settings. Thanks!!!
Hi Mr. Pete,
I bought a 13B a few months ago and somewhere in the information while investigating the machines before I purchased it, I found something that makes me think the Chinese that don't understand English believe drill bits are called end mills. There was some misinterpretation and I don't know where I saw it, but it answered the same question you are presenting.
I also bought a Vevor MR 20G that grinds up to 3/4" bits. I have used it some, buI had most of my hundreds of bits already sharpened on the 13B. I almost sent it back until I realized the collets were dirty. The 3/4" (20mm) collet is about the limit of the machine and is very thin. It apparently had something on the collet and I couldn't get it to seat. I finally put the collets in my ultrasonic and lubricated them with WD 40 lithium grease and they work fine.
I have wanted a Tormek T8 for a long time top sharpen my hundred knives, so I am going to spring for the extra ~$400 and buy the drill bit sharpening kit. It will sharpen up to 7/8" bits. It uses the facet sharpening method rather than the radial method most sharpeners use. It looks to be a lot slower, but it will be interesting, I have never sharpened using the facet method. It looks very precise and is probably a better way to go with some bits?
It will be interesting!
I think you are right about the Chinese terminology. I just don’t understand why they don’t get at least one American to proofread it.
I was thinking about getting the larger drill grinder, but it still only goes up to 7/8. I would like it to go to about one and 1/8.
I seem to find different grinders without really looking for them so if I run across a reasonable grinder that large I will contact you. @@mrpete222
Hi Mr. Pete,
As I mentioned in my reply, I seem to run across this stuff without much effort. Obviously the UA-cam algorithm knows what I am interested in.
Here is something that may be of interest to you regarding sharpening one inch plus drill bits. You may have already seen it?
ua-cam.com/video/t3KJ9vksuGc/v-deo.html
@@mrpete222
Learning from the Master. Long live, Sensei!
Don’t need one, I just like your videos
hmm maybe throw those in a bag of oil in the ultrasonic once in a while to keep those collets clean from abrasive dust that will eventually wreck them. I see the most precise toolmakers clean the collets frequently, particularly after lapping paste, after rotary lapping. some diamond dust might get in there
I asked Vevor if it does end mills. They said NO, they do NOT.
Thank you for telling me that. I hope they correct their ad copy.
Will any of the 3 Machines sharpen LEFT HANDED or counter clockwise bits? I bought out a Bankrupt Machine shop and they must have LOVED them because I have thousands of all sizes of Lefties!
Lol
No, it will not sharpen left-hand
@@mrpete222 I could, but you'd have to make a mirror image of that piece the collet holder goes into with the ramps going in the opposite direction. Would be a fairly easy project on a CNC mill :)
Lyle I have the drill Dr sharpener and it does perform well. I even have the left hand drill collet adapt for mine .I think its the 750 model. I'm an old machinist and my eyes just aren't as sharp like a razor anymore. I definitely would buy a vevor if I had none.
Thanks for telling me that the drill doctor could sharpen left hand drills
Great video still haven't got one yet .
Thanks for sharing MrPete! I think I'm going to order one. I have an ancient copy of Henry Ford's "Shop Practice" that has a section on drill bit geometry. It's quite informative.
Thank you for pointing that out. I have a copy of that book. And I will mention it in my follow up video with my giant drill teaching aid.
@@mrpete222 Looking forward to it!
Hey, going to watch rest of video but old boss bought us a drill doctor which I have halfway mastered, my biggest tip is to scrunch down the tightness after setting tip. One or 2 clicks positive if drills being sharpened have split tips. If you are splitting tips grind first and then reset tips then split.
Ok I don't like drill doctors. But I have found out how to make them work. Bigger bits I have a Starrett drill point guage and I put on my good glasses. Damn I hate getting old, I used to be able to see .005 no problem.
Best drill point grinder I have ever used was a Diamond brand, expensive piece of kit, center of center drills no problem, could play with clearance and make special countersinks. Great machine.
Might have to talk new boss into one of these vevors, just watching to see your recommendation.
Thursday, our cnc guy kept bringing me drill bits to touch up, gee. Drill doctor got it done. He didn't come back.
I need to get n me a set of those magnifiers that go on my head like yours. Ok I have got a set at home but none at work, just a big lighted magnifier. Other guys use it too.
I feel for you. Period. I pretty much I have only one eye. I need surgery on my right eye.
@@mrpete222 hey my eyes are actually still better than most, just really small stuff. I had me a trainee until last week, he is on days now. Boss wanted me to make sure he knew how to sharpen drill bits. Ok he has seen one sharpened now, had to get out my good glasses, 2.5 diopter on reading lenses. I use 1.5 in shop can see dials on mill, then I drag out scratched up reading glasses which are 2 diopter. Then the 2.5 prescription glasses the safety guy says I can't use because they don't have the right stuff written on them. Gee. I put side shields on them.
Anyway., new guy has at least seen how to sharpen a drill bit.
Ok going on. So now I am a machine shop instructor. I spent 2 years in votech back in 78 80. Went to work in a machine shop that fall, boss gave me prints or a sample, I made them no problem, even went through the inspection department of the place we were working for. Had to train this kid how to tighten and loosen a collet in a Bridgeport mill. Ok just a couple turns loose and smack it. Gee. Sawing stock, had to instruct on how to read a scale. Forget about decimal equivalents. 1st year at vo tech we learned them by 1/16.
But he is a good kid wanting to learn, got hope for him.
You being a teacher must have had much patience.
Got to add one more thing. Kid got a lot of safety training, safety when I was that age was wearing safety glasses and keeping out of way of the rock and a hard spot. Grinding I was always taught to fire up spindle and get it warmed up. This kid would shut off spindle to check parts on surface grinder which he had never ran in 2 years of vo tech training. I know, safety first, take it over to one side but leave wheel running let spindle get warm keep warm was the way I was taught. Old machine shop teacher I had told how he was first one in shop to fire up the grinders and get spindles warmed up before the guys got there. Still to this day if I have surface grinding to do I will start up spindle when I get to work and let it warm up..
Blocks, kids these days don't take classes they take blocks. Haven't figured that out, we just got on bus and went to votech for 3 hours a day for 2 years.
Ok, I think I am over rant now.
The 3 4 or 5, maybe 6 weeks I had my charge he did learn a lot, not his fault he wasn't taught stuff in high school. These kids are our future, pass on knowledge. Btw, I need to do a single pointing class some day.
I found this under the "Questions and Answers" section on the product webpage:
Question:
What end mills does it sharpen? 2 flute only or 3, 4 5 flute end mills?
Answer This Question
Answer:
No, it cannot sharpen milling cutters.
By vevor on May 08, 2024
Thank you for that. I will post that in a future video. But I already warned people that it does not allow you to sharpen milling cutters.
By end mill grinder sharpener, maybe they mean the grinding Wheels?
I wondered if a drill bit could be considered an end mill. Essentially a mill that only cuts on it's end and not it's side.
I recall watching Keith Fenner wanting a hole to be perfectly symmetrical, he went to the grinder and knocked off on side of the drill tip and wanted only one chip...
Oh darn I was really hoping to get some pointers on splitting those points and thinning webbing in this vid, guess Ill have to wait. I am curious as to whether those operations can actually be handled by this machine however? Oh nevermind I see! I should practice more patience.
I've not used this machine, but it looks like you put the collet in backwards at 7:32. When you showed the 1/4" bit in the collet at 7:14, the collet was inserted with the tapered collet head to the tapered section of the holder.
Thanks for the video. I have been sharpening mine by hand on a bench grinder and I want to get way from it. Can you explain drill bit coatings and if any of them affect resharpening? Specifically, I'm thinking about titanium and cobalt bits.
Lyle - Good video. This product seems to fit the quality/repeatability space between a Drill Doctor and a Darex. I had an early Drill Doctor that I used for years but eventually the plastic alignment went out - by playing with it I could still get it to work properly. Like you said, as long as you understand the bit geometry it really helps when sharpening. Like most any other eye hand coordination task practice helps a lot. If I had not found my Darex at a school auction for about $100 I would be looking at a Vevor. Sure looks like a good machine. If you play around with the depth of grind and those multiple pin locations does that somehow set the angle correctly for an end mill? Interesting problem - bet there is something like that to accomplish the end mill grind.
I think that’s a good comparison between the three grinders.
I still hope to borrow a Derex grinder someday to make a video
If you haven’t done it already, I would be interested in seeing you do a video on drill bit geometry, and hearing more about your drill bit instructional aid ( e.g. what was it made of, how was it made?)
I now have the giant teaching aid and that video will be available eventually
I think This Old Tony did a video on drill geometries, and hand sharpening - there's probably many of them around on the tube
This may sound like a novice question, but what are the two different grinds used for? Thank you.
Greetings, Mr Pete. I'm ready to pull the trigger on one, but I'll wait until you explain the point splitting feature. Might note there is now a $100 difference in price between the A & B on Amazon.
I didn’t realize they sold them on Amazon
@@mrpete222 Indeed, they also have what looks like the identical machine under different makes, not Vevor.
I purchased the 13b after watching your video. Not having watched your 3rd video yet (it’s not posted yet) I’m not sure I made the right decision because I think I might like the split point rather than the web thinning feature. I’ve successfully sharpened bits from 1/8” to 1/2” and had no problems getting a good clean edge that cuts like factory. All possible only because of your video. The instructions are horrible and even after knowing how to use it, I went back and very carefully read the instructions again and I can’t make heads or tails out of it. It’s really bad to the point of making me mad. I found it curious that they make no mention of the web thinning knob and how it functions. I’ve loosened the hex nut holding the pivot point, and turned the knob from all the way from left to right and found it doesn’t do anything, arggggg!
I’ve also found that all my bits have what appears to be a grind of around 114 to 115 degrees so I adjusted the angle accordingly leading me to believe the scale is slightly off. No big deal since I’ll set it and forget it and I’ve made a mark where the grind matches the factory edge. All in all it’s a good machine with instructions that make reading them the equivalent of the Bataan Death March, and using it like a day in the park. Thank you so much for your clear tutorial that without I would have been pulling my hair out.
Yes, the instructions are in chinglish I can’t understand why they don’t hire an American to write the booklet. Once you master the machine, you don’t need the instructions anyway.
And yes, they pretty much never mentioned point thinning
It is not really the equivalent of the Bataan Death March unless, if you stop reading part way though, someone bayonets' you in the back.
@@bwyseymail Ha,ha, Well it was almost as painful as a bayonet in my back.
I have the newer Drill Docktor and the one problem I have is getting the relief angle, I see this is a common problem, without the proper angle the drill doesn't cut. Seeing this machine makes me want to try it out to see if it will do a better job than the Drill Docktor.
Yes, I have the same problem with my drill dr, especially with smaller diameter drills.
I do appreciate the standard measure as the metric(SUCKS) is not used in my use 99 percent of the time.
I own a Drill DR (3/4 inch ) and I have had and do have success using it BUT, I've had my issues etc...I think drill dr biggest problem is the base is light weight and so is the chuck. Also instead of mechanical action i.e the lobe of the vevor, the drill dr has a lobe on the chuck and that makes it awkward to use
Thank you. I still intend to make a video on the drill doctor.
Many people have told me they love their drill doctor
It is a widely known myth that CE stands for China Export. CE stands for Conformité Européenne. That translates into European conformity. It just means it meets European product standards. If you have an electrical item that has the power switch on the back of the machine thank the Europeans. One of their standards is the switch has to be within a set distance of the power cord.
It is not a myth actually.
*C E* stands for *Conformité Européenne*
*CE* stands for *China Export*
The only difference is that small space between the letters.
That’s not entirely right. You find hundreds of cheap Chinese products on Amazon and eBay with this prominently displayed on the product. But ALL of those are standing for China Export. Anyone naively thinking these meet an EU standard will be shocked to find out that they meet Bo standard. At any rate, I’d far rather have products meet the stricter UL standard here. But you certainly will never see that on a cheap Chinese (or Indian) product.
I have seen a dokumentary about China long time ago. There they said that the China CE stands for Chinese Enginering. They are writing CE so people belive that it is true CE standard to fool people.
You sound like you know! I had always thought it was the European or Canadian equivalent of UL. It does appear to be frequently displayed on inexpensive electrical equipment from the Orient.
I'm not sure about any of that other stuff but I work in a factory here in Missouri making heaters. I work in the machine shop and a ton of the parts we make we will stamp a CE logo onto. Obviously none of our stuff is exported from China to us. Most things that get that stamp have requirements even on where the steel is made to avoid that shit that comes from China
made from schlitz cans that warshed up on shore. (he knows what i'm talking about)
Could the extra diamond grinding wheel be also used for regular drill bits ? Thank you for all your work in producing these videos.
I would say no
CBN and Diamond should behave similarly if the grit size is the same. The high-end Darex sharpeners came with diamond wheels.
I could not find the listing for the replacement grinding wheels on the web site printed on the side of the wheel. It shows grinders but no listing for replacement parts.
CE doesn't stand for 'China Export'. The CE mark is a European product conformity mark ("conformité européenne"), it signifies that products sold in the EEA have been assessed to meet high safety, health, and environmental protection requirements.
I was hoping everybody would watch the entire video. Near the end I thought that I clarified what the CE actually meant.
Don’t feel bad if you missed it, no one ever watches the entire videos
@@mrpete222 I did watch and very much enjoy the whole video, Pete. I'll say again their use of CE does not mean 'China Export'. If you look at it the letter 'E' is actually in logo form meaning they are displaying the actual European 'CE' mark logo on their products. CE marking is a self certification process agreed to buy manufacturers - they agree that their products will meet certain standards, in particular safety ones. It is common for Chinese manufacturers to stick the Europen CE mark on their products despite not adhering one jot to the conformity regs. To that end all Vevor electrical products have been withdrawn from sale in the UK due to the governments concerns over safety.
Lyle, Please explain the purpose of a split point and a the different degrees of the drill points.
That is explained in the still pictures at the end of the video
@@mrpete222 I could not see it all because the info was not centered and a preview of the next video blocked a portion of the info.
It would be good/better if you could use different sized collets!
Thanks for sharing
Thanks for watching!
You have to show the drill being used on hardened steel.
Which one would you recommend the first machine or the second one
It’s a tough call, but I think 13 B, the more expensive one
Its not rocket -science, but rocket science sure helps! LOL!
The Vevor I received had unequal collets. The 3 smallest collets were longer and seem to interfere with the storage door. Are your collets all the same height? Does the inequality affect the indexing of the smaller drills?
My smaller collets are shorter than the larger ones. I believe that is the correct design. I actually have not sharpen any drills that small yet. Experiment with it.
@@mrpete222
Thank you for having taken the time to answer. Jim
Clarify...I thought diamond could not be used for steels because the heat of grinding causes carbon to transfer from the diamond to the steel.
I’m not sure what I said in the video, but the diamond wheel is meant for carbide drills
May I add to my previous comment that after leaving the military service ( Honorable
Discharge) in the mid 1980's, I became Master certified as a Auto and Heavy truck mechanic, and later a Certified Machinist as well. I made my living in these career fields ever since. That has been quite a while. I just wanted to express that the VEVOR purchase I made, with what I believe to be false advertisement , is WRONG DOING by that Co. and it should be MADE RIGHT.
👍👍
6:10.. typo.. happens alot actually
Unable to find where to purchase replacement grinding wheel and will greatly appreciate it if anyone can provide information about where the grinding wheel can be purchased
The wheels have a website written on them I believe
@@mrpete222I checked the Taiwan manufacturer’s website, however, no information about parts for the machine is listed. In addition, the web address on the grinding disk isn’t accurate.
CE stands for Certification European, that means that the European requirements in terms of electrical saftey (for example propper ground wire) are done. Without such a Test and lable the device can't be sold in the EU. Neverless some low coast china manefacture just invest in printing the labels without doing a lab test :)
😂
ok i just bought the highend modle from amazon 429$, based on your say so, what a sucker i is
I did not know that Amazon sold them
@@mrpete222 Vevor sells almost everything on Amazon, but it's always more expensive, as you have to pay the bozo, err I mean bezos tax...
Probably mean you can turn endmills into drill bits 😅
You may be right, I never thought of it
Why no one demostrate smaller drills on this. Those are most hard to grind by hand and this would be useful for them them most. But I saw many videos about it but none demonstrated smaller drill bits.
I have called intentions of making a video for smaller drills, but only if I get lots of views on these videos. I will not go below 316, just buy new ones.
@@mrpete222 sometines I need smaller drills to shorten them. I just wonder is that limitation of machine or you just dont want to bother? I am mostly interested for 1/8 (3mm) to 8mm. I did 3d print mimic of that machine (inverted er32 collet) and had good results. That machine should do better but I wonder...
Getting the extra wheel would be worth the $30.00 even if you didn't use the additional features.
True
Looks like the vevor, preasion, and grizzly are all the same units.
Did not know that grizzly sold them
I got mine and love it. But what does the know on the upper right do?
We begged and pleaded with the owners not to buy a Drill Doctor but the Vevor instead but no,they would not listen for their hearts had grown cold.
Just like pharaohs heart hardened
Up to 1/2" dia.. Drill Doctor goes up to 3/4".
Really it goes up to 3/4, I will take a look at mine. I don’t think it goes that high. Maybe they made different models.
Sadly, these drill grinders are not available from Vevor in the UK
I wonder why
There's so much on Amazon marked as "unavailable at your location please choose another location" Sometimes they are half-wits. (Also in UK).
They are available under different names from Amazon
CE actually stands for "Conformité Européenne" or European Conformity.
Not sure why anyone would need 3 drill sharpeners
No one needs three sharpeners. They need eight or 10 sharpeners, that’s how many I actually have. Crazy isn’t it but the whole purpose is to show you the different models and what they can do or cannot do.
CE is conformite europeenne we used to say it was checked for Europe though now Britain has left the suits the French version. It w as on everything not just Chinese imports it replaced the. Kite mark here though it was nothing like it and only covers the product not the tools that made it or the canteen.
"Suits" should read "Eu it's"
👍🏼👍🏼🙏🏼❤️🙏🏼
If the story about the CE mark is true then it is clearly designed to fool purchasers. The European authorities would then take legal action against the importers for misleading markings. Could your explanation possibly be just a conspiracy theory or do you have evidence that the equipment is not "Conformité Européenne" compliant ?
CE marking means "conformité européenne"
Not the chinese version...
The end mill statement is obviously an error on their part, but they still haven't updated the website, so they don't appear to care much about giving accurate information to potential customers. Typical chinese indifference.
Yes, I was wondering if they would correct it. Yes indifference.
It is so nice that you are a spokesman for china.
Yes, we all support China by buying from Amazon, Walmart, the dollar store, and every other store in the United States that carries almost everything from China
He is explaining the use of the machine . No way is Tubalcain a Chinese agent - China makes just about everything thanks to our consumer habits. Our fault not theirs. This was a really helpful and quite fun video. Great teacher.
I don't know where you got your information from, but CE does not mean China Export. I thought so long ago, but was absolutely told NO, it does not mean that, it is a misconception that a lot of people like to promote. en.wikipedia.org/wiki/CE_marking from wikipedia (read more for full info)
The presence of the logo The letters C and E in a stylised ligature. The E is a lunate epsilon, shaped like a letter C with a horizontal bar. (from French, "conformité européenne" meaning "European conformity")[2] on commercial products indicates that the manufacturer or importer affirms the goods' conformity with European health, safety, and environmental protection standards.[3]: 58 It is not a quality indicator or a certification mark.[4] The CE marking is required for goods sold in the European Economic Area (EEA); goods sold elsewhere may also carry the mark.
