Super interesting thanks mate🇦🇺

😊thanks for the awsome video!

Thanks. A very good video. I'm trying to think back to my college days, but doesn't the 3 degree back rake on the top of the tool tend to narrow the 60 degree included angle? Form tools don't usually have back rake. Not a criticism, just a question. College was a long time ago.

excellent class ! thank you, best regards Steve

Super travail bravo 👌🤩🤩👏👏👏

Outstanding video!

Another great video with pertinent information and explanations. Thank you 👍🇳🇱

Excellent and useful video, thank you.

I am really enjoying your cutter grinder videos. There's not a lot of info on running these machines on UA-cam or elsewhere. A few people who have done a good job of figuring it out themselves (Steve Summers) but you are clearly a pro.

That is a interesting project. Never even thought of cutting a saw down. Nice work mister

love your videos! you sure know your stuff! Thanks for sharing with us

Awesome and use full info as always Thank you, keep making these gems.

I'm glad you are on the mend! I work on a rural ambulance professionally and with my hometown fire department as well. I advise you to follow your doctors instructions and you are more likely to be back to your old self quickly! Sorry, I couldn't help that! I never thought about the axial relief on a tap but it makes perfect sense to me, now that you have explained it!

I actually was wondering about grinding a screw slotting cutter thinner to fit a smaller slot! I always enjoy your videos! I think if I try thinning a screw slotting cutter that I might not thin it all the way to the arbor in order to retain rigidity, what are your thoughts? Thank you!

🤟🤟🤟🤟💪💪👍👍👍👍🇷🇺

I forgot to ask, are you grinding right up to the shoulder of the hub of the cutter? I’ve a er40 Morse taper 5 holder to grind the flats slightly smaller to fit my mill and wondering whether to grind right up to the shoulder? And if so should I dress the wheel with a sharp corner to get into the corner? Thanks!

Thankyou Andy and Tonya great info and video !

Excellent work. Thanks for the info 👌🏻

How long do you expect the diamond to last? I was shaping a small point (1/2” dia 1/4” wide) it was broken and jagged and I need to true it up. I got pretty significant wear on a new 1 carat diamond. (Cheap eBay diamond). That seems excessive. I am thinking it is just a crappy diamond. It was black in color.

Fascinating. A master at work. Thank you 👍🇳🇱

Très joli travail bravo (France)

Fantastic info as ever! Thanks from Scotland!

Мне нравятся ваши видео, спасибо вам за ваш труд!!!!

Вы крутой человек , привет из России !!!❤❤❤❤

thank you for accepting the challenge. There is no rush at all, every detail counts when learning. I use 6mm end mills on my CNC mill mostly more as a machine safety. 6-8mm tools snap much quicker compared to larger ones, and the machine itself won't suffer or deform when happens. These very good small and thin CNC cutting tools nowadays are expensive too. So, it is worth sharpening them. (Carbide end mills). There are not professionals enough for this complicated sharpening jobs, and not because end mills very chip. They are not chip any more. Thank you once again.

Interesting exercise, like your thread grinding setup! Instead of centre drilling the M2 HSS blank, had you thought of grinding a male centre on each end instead and using female centres (easily made) in the cutter grinder?? The male centre can be made as large or small diameter as you need depending on the size of the workpiece.

Is the fact the tap is presented to the grinding wheel at an angle the reason that you get some (most) radial relief and some axial relief? Or it the relief fixture capable of independently varying the two reliefs? Thanks in advance and hope your recovery is smooth!

Ok.

Like always, great video and info.

Thank you for the videos! Found you after picking up a KO Lee for myself. I believe you mentioned that you dont have the proper setup for sharpening drill bits on your cutter grinders. On the KO Lee, what would be the proper setup?

Well done and great camera work !!

Yes , very good indeed, as good as all the rest of your videos are. I want to see you sharpening/grinding 4-6 mm end mill and drills. Not as an exam..., this seems to me more intricate job and I have to learn doing it. I thought of using a camera. I wonder, you as a professional, what is your way/approach. Is there any other tiny set of tools for this job, or....? I have a good grinding machine here (3E642e universal grinding Russian machine ). Just learning now.

I'm a hobby machinist and also have a smithy and like it but you got use it like a smithy, not a bridgeport or engine lathe. I have mine mounted on a harbor freight 72' tool box with a regular kitchen laminate countertop. The tool box wheels were removed and a 4" square metal base installed with leveling legs. For drilling, I'll use a ER 40 x R8 collet and then use ER20 x 6" collet in that. This setup gives me 5" of travel without moving the mill head. The best thing you can make is a solid tool post for turning. It'll seem like you got a bigger machine. I was using the lathe as a mill in this video but you'll get the idea of the solid tool post.

Get better Andy

More Great Information on sharpening. Thanks!

Thanks for another great video! How small of a reamer do you consider feasible to grind with ordinary equipment?

Great info. Thanks mate

Good info. I need to get a set of centers. What grit stone are you using?

Do a chamber reamer for a barrel next video

I checked some old grinding notes I have and Cincinnati Milacron calls it "eccentric relief" which I think is also a good name! So "cam relief" or "eccentric relief" or "progressive axial relief" all could work for me.

I thought about the value of that drill and concluded who cares? It has entertainment value way beyond $5. Adults have to play too.

Thank You.

So glad they “fixed” your kicker. Appreciate your content for sure. Keep that kicker kicking.

Angular relief on a tap may create too much space on the back of the tooth. This becomes a wedge shaped space for chips to enter as the tap is retracted and cause damage to the thread or even break the tap.

We are most grateful you are here to do your show Andy , great video!

Glad you are back on your feet!

I have two hybco heads. These heads make sharpening taps easy. One is used only for sharpening gun drills. What is the new machine you mentioned. I could not see what it was. Your videos are great. Sorry to hear about your health trouble. Not many places have the hybco heads and very few people even know what they are. Do not stop making videos. regards.

Stay well!

I think one of the reasons to use a cam relief vs an angular relief is how wide the flute is. If it is wide, you end up with primary, secondary and then a third relief angle to ensure clearance. I think that is why countersinks tend to use the cam / elliptical/ conical what ever relief.

Спасибо за основательный теоретический подход к проблеме. Надеюсь увидеть практическое исполнение на станке. Также надеюсь, что Вы окончательно поправитесь и со здоровьем у Вас все будет хорошо. Здоровья и удачи!
