Only a machinist can understand the love of that "pop" sound of a well drilled hole.
Give your cameraman and editor a raise, this is super cinematography! Also that behind the scenes at the end is hilarious :D
RIGHT!!! That's exactly what I would do if my hole came out that *chefs kiss* perfect size
Jesse, your videos and Tyson's videos are the best. You're not trying to be extreme over-the-top like a couple of other people.
Thank you. We all are trying to educate but also try to make it fun and entertaining at the same time.

Love all the videos brother.✌🏾
@@jamstagerable Thanks man! really appreciate it!
Just had my first day in a machine shop at 27 and was blown away. I come from a construction background and made a career change and have never been happier.
Did you have any experience? I'd love to get started but have zero experience and don't know where to start
Top G's of CNC. It's been enjoyable watching the production quality increase over the years. This is grade A content for nerds.
Thank you!
Flat bottom drills,
You make the rocking world go 'round
😂 I was singing that to myself just the other day!
LOL that is gold!
I was looking for this comment. Good job.
Very cool. I was not even aware of those drills but I will definitely check them out. I have used flat bottom spade drills but not the Go drill. Thanks Jesse
You guys are awesome, I learn so much from your videos...even if I'm just using a diy cnc. Knowledge is power!
Great video! Awesome skills explained mixed in with comedy! BOOM! Put a smile on the face! Love watching you guys! Have a great day everyone.
Glad you enjoyed it. That's exactly what we try to do. Educate and make it enjoyable at the same time.
BEAU NOGOH IS BACK! We need to get another episode of him 😂😂😂
I AGREE 100%!!!!!
That pop-up pin sounds truly amazing,BOOM
Great tutorial, seriously impressed by the size accuracy
You guy's are the best! Video quality and style great! AND THE INFORMATIONIS IS PRICELESS!

Happy to see Bo NO-GO back in front of the camera, In all seriousness, keep up the great work guys!
Yeah someone left the door open and he found his way back inside 🤣
LOL
Great video, there was a couple of important points I thought you were going to ignore but you got to all of them.
Thank you!
A video of me furiously pushing the feed % up / down button while drilling with an endmill would be less entertaining but more accurate to real world conditions. Which isn’t to say y’all aren’t real world. You just have a really nice shop, deep tool pockets, and time to make videos. I’ve got 5 different drill indexes of various completeness and a bucket / drawer of misfits and stragglers. Good luck getting the boss to pony up for fancy drills.
as far as i can tell they no longer run production jobs. just some spacecraft stuff here and there and otherwise they make videos. i speculate they get the machines on loan as promotional equipment.
Great video! Learned something new.
Awesome Video Jessie! All you all got the experience of a lifetime with the one and only Machinist & Extraordinaire! Bo No Go! 🤣🤣🤣I'm voten fir Bo No Go as President!
I think Bo could get the swamp in DC straightened out! lol
Thanks hadn't heard of these drills.
Loved this - Gotta stay for the ending hahahaha! 🤣
Awesome video Jessie! Need to get me some of them drills
Nice Editing and good information guys. I like that there is no boom. 😜
Also i like that you pointed out the circumstances of the method. I just like to say that this method will reduce your toollive.
Nicely done
6:18 That sound when you pull a pin out of a hole is 👌
When you can use the air in the bottom of the hole as a spring and bounce the pin up and down, on the other hand... 😘👌
Well done!
Mullet boy I was impressed I really was the technology specific applications for this stuff is just mind blowing to me I’d love to see what this technology is going to be in 20 more years
Flat bottomed drills make my rock and roll world go round.
nice new 5 axis mill you walk by at the end.
Nachi flat bottom carbide drills work fantastic at plunging different angles also.
nice pop sound when testing hole size good machining !
i use a flat drill now for 5 years they amazing, from yg-1 that are not so new but the most didn now they exist
The last bit is hilarious 😅😅😅
An old man once told me what you have there is called a honeymoon fit😂
Great vidio thank you for sharing very good
Oh yeah, I used those before. The problem that I ran into was the drill substrate. We were using the "glass metal" fb drills. So when you wanted to drill on an angled surface on steel, you had to peck drill about .001" increments. I found this out after breaking a couple of them. I think that I would have been better off, and safer, to circle mill a flat then continue drilling.
Great video on methods to drill angled holes. Any tips on how to make sure the location and depth of the holes are to spec? preferably w/ out a cmm?
Great experience
These are a great application on bigger applications , but for smaller holes check out the micron crosspilot drill ,these can drill down to small sizes on steep inclines with no deflection, because the hole may not be a through hole and may have a drill point, and they can drill 10xD
Great video and it's tight lol pop have a good one guys 😮
In the end I expecteted Donnie sayin' "you perv", but the look did that much better )))
6:06 sounds very nice! Quick question, though. You haven't chamfered the edges of the holes at all. Doesn't the burr throw off your measurements with the gauges?
Barry and Jesse i think you should to fight a duel to see who makes the bigger chips 😂
Hahahaha beaux nogo. Good stuff as always. Love me some Godrills. Much love and gratitude
Thank you!
When we have a flat end in the hole, we drilling with a regular drill first, and then we finish it on the last 3-4 millimeters with a flat drill (depth dependening on the diameter). The flat drills tends to collect more chip, which we have to pull down in every 20-30 minutes working with stainless...
Awesomeness
Almost thought that poking Berry woudnt be there :D nice
Hello. Great video!
But why have you stopped showing us feeds and speeds?
How do you do the feed reduction in a mastercam drill operation? or did you just longhand write it?
That is perfect
Pilot with a ball endmill too if all you need is to reduce deflection. Just get one close to your drill size.
You sort of remind me of my old busy Jet Jackson from Oklahoma.
Barry's biscuits are burning!
LOL his biscuits have been burnt for awhile!
I'd love to know how well these hold positional tolerance? The logic being that if your flat spot drifts it's unlikely to cause the drill to wander as the point is still starting somewhere on the flat, where as with a flat bottom drill because it's cutting on one side the stiffness of the tool probably comes into play with regards to the tool pushing off. I'd guess it would depend on diameter? The diameter tools like the ones in the video are pretty stiff, so it's probably not an issue.
my thought exactly, he didn't even show the position and how much it is in the tolerances because smaller flat drills will go off center nonetheless in such a angle until I see any prove that the position tolerances are met with this technic aswell I trust this video with a grain of salt ngl...
That face you make when that 500 pin just sliiiiiides right in
What’s the tool life like on these flat bottomed holes compared to a regular pointed drill? I’d presume it’d be higher wear amount on the tool because of the 90 degree edges
Like anything it depends on the situation that you're putting the drill in but the tool life will surprise you. We used these at my last job and the tool life was way better than the endmills we were trying to use.
@@Jessie_Smith but flat bottom drill IS an endmill... Maybe your experience was due to the change in tool manufacturer?
@@feedbackzaloop A flat bottom drill is designed for plunge cutting only.
@@jamstagerable yeah, just like the endmills in their early days. Considering popularity of plunge milling for HPC the difference between modern mill and flat drill is negligible: front face cutters do all job.
Cool. So the right drill bit is a better solution than trying to add extra steps to make it easier to drill with less-optimal bits. I don't do CNC, but this side of engineering's really cool.
Though, how do you figure out how much to step down the drill speed, and for how long before you know it's making full contact? Is that entirely because of prior experience, confirmed by a little trial and error? Is it tool-assisted where your program has presets? Or is there prior information with how the drill bit is spec'ed?
Probably a bit of all of them at the same time
If you're looking to cut cycle time or an extra tool then using a flat bottom drill in these situations can be a better option. As you see in the video I am leaving the RPM the same but reducing the feedrate by 30% to enter the holes. That number came from Kennametal as the starting recommendation. With any tool like this or out-of-the-norm process, the manufacturer will have some basic guidelines as starting values. I always try to use those first and then build from there depending on how it works out. So my best advise it to take the available information (because it's free and someone has already done the research) and also your experience and use those as a starting point and then build from there.
I just looked through Kennametal's offerings on flat bottom drills and I can't find one that goes deep enough. All their offerings are 3xD and I need at least 3.5 or 4xD for my particular projects. Just over 9/16ths hole at 1.925" depth with a flat bottom.
What about deep holes ?
Do they make long flat bottom drills ?
Always thought flat faced drills are the way to go in the long run for clean starts/openings. Especially for any hole not at a 90 on a flat surface.
What if i need to drill 25X diameter? Im having alot of trouble drilling 4mm at 75 degrees angle.
Is the posted GCode a Seq of G01s with the feed changes or does Doosan have a CAN cycle to address that?
Since I used Mastercams 'Advanced Drill' toolpath it didn't output any canned cycle so it was straight G-code with the feed changes.
Two questions:
1. I understand decreasing 30% until the whole bit is engaged with the work. I'm curious why you decrease by 30% when you're exiting the piece on the opposite side?
2. What is the difference between a flat bottom drill and a center cutting end mill?
Thanks.
1. The same reason when entering the hole; to reduce/eliminate the change of the drill chipping when entering or in this case exiting uneven surfaces, plus less burrs around the edge of the hole.
2. well, with a drill you can only drill, and with an end-mill you can still drill, ( though certainly not as fast as with a drill) plus do other stuff while at it.
How do you reduce feed in Mastercam by 30% to correct depth?

Hey I was kinda wondering how you got your start in t he cnc space, becasue I'm just a high schooler who was trying to become a machinest. I have been using cad since 6th grade and am very good at 3d printing parts and wood work. I kinda figured out how to make tool paths in fusion and am learing how to use a cnc router at my school. I just don't really know where to go from here.
We have an academy online where you can learn our curriculum for free at academy.titansofcnc.com
Reach out to our team on there if you have any other questions. Awesome to hear you're interested in becoming a machinist. You came to the right place!
Jessie, I do believe you just laid out almost all the issues involved with drilling a bowling ball, except for what it's made of.
So how was the cmm?
it would be cool to see it beeing measured. i wanna see youre machines :DD
That is a really nice invention, but in some situations I use the drill cone at the bottom of blind holes for clearance. Would be an unpleasant surprise during assembly if that was left out by this drill.
Then you'd need to consider that change while programming
@@angrydragonslayer True.... in a perfect world ;)
I make the drawing and 3d model, than another department sents that to a job shop and they make the part often without ever talking to me. If they don't call and ask if flat bottom blind holes are ok - and why would they ask that, because it usually is ok and nobody cares - the parts come back to us and then someone from assembly department calls me because my parts don't fit together. Maybe actively using that drill bit tip cone as a feature for clearance isn't such a good idea after all.
@@ensen89 well, it isn't and in your scenario, it's far from ideal.
There are cases where a flat bottom is required by design, maybe underneath the holes where it normally exits is empty space and the engineer wants to maintain a wall thickness that the drill cone would thin.
oh, angled holes... for some reasons 90% of our client toolmakers hate them. especially holes like that last deep hole there that is angled in two directions to the cardinal axis,
even more if that require drills in the category of 40xD 😁
I wonder what comes next? The difference between milling an O-Ring groove, or using an O-Ring-countersink ?
Barry!! Barry!! Barrry!!!

hmmmm.. lmao, kids loved it.
How in the #$&@ do they put the coolant holes in those drill bits?? 😳
That little popping sound when you pull out the 0.500"... Mmmm...
i love the sound of a caliber 🤌🏼👉🏻plub🤤👉🏻👌🏻😆
"If you are a machinist, chances are you already know how to drill a hole." - not all holes are created equal.
If only they could show why they make that piece and where it goes !
I think they're trying to get us to buy a new drill.🤔Just my guess. Hope they throw in a totebag.
it was only a piece for illustrating his technique. it's not for anything.
@@ronblack7870 Don't get me wrong, I enjoy what they do. But in the end it's a commercial to sell machines and tooling. It's brilliant. Just like that silly old show "American Chopper". 42 minutes of product placement and air time for the client.
hairstyle-NO GO guy
I’m still confused why you wouldn’t just mill the start of the hole considering as it only takes a few seconds and can cater for multiple hole sizes whereas a flat bottomed drill wouldn’t
Rip Barry Setzer.
LOL I am still here!
Why not drill the holes first, and THEN mill the rough part into the desired shape...?
because it's not a part. it's a demonstration piece for the video. he said that.
I had no idea that you guys that are lucky enough to have a CNC machine had to contend with a problem like these holes. I thought the machine could just do it?
CNC machines enable tool paths that would be impractical to do on a manual machine and save labour on complex or repetitive jobs..
but it's still up to a human to decide what tools to use, in what order and with what feeds and speeds. There are nearly always multiple options, you could mill a flat with an endmill and use a regular drill, you could cut the entire hole with the endmill if it's not too deep. Each option will have tradeoffs in speed, quality, tool slots used on the machine, and whether or not you have to buy new tooling or can run what you already have.
Why not mill the holes
Milling the holes would be much slower in a production setting.
A lot of Titans videos are BS which is why I unsubscribed. This is definitely worth watching.
With like 1300 videos on UA-cam … you can’t win them all. We definitely try to keep things exciting and at times go to the extremes to show the boundaries are much further away than we thought… which allows machinists to have confidence in pushing their tools which equals a better profit… at other times we explain process… and other times do full part tutorials… and at other times we tell real machinists stories so others can learn from our experience. All in all… we’re driving thousands and thousands of kids to machining who otherwise wouldn’t know what it is and we’re helping companies compete and make money.
Many channels die because they do the same thing every day and don’t come up with new ideas…
We’re always pushing and learning… and adjusting… just like we do in the machine shop.
Sorry you unsubscribed but… thanks for the positive comment.
Our loyal subscribers help us build a platform that reaches the otherwise… un-reachable.
@@TITANSofCNC do you actually run any production? that would impress me. i believe you guys only make videos these days and sell stuff in your store. running high production is really hard. doing one offs with new machines and new tooling is puff work. do you even own the machines? or are they on loan as advertising for the makers?
What if your hole has a hole??? ;)
Now how do we do it without the $800,000 machine?
Dude sounds like he's from young Sheldon....
Too bad you did not check flatness and perpindicularity of counterbores. Efficiency doesn't pay that much if you need to use a counterbore mill anyway.
Yeah, first you need a cnc to make toolchange quick and automated. Now you need this drill to eliminate toolchange . What's next?
Isn't that just a slot drill?
Haha
This channel doesn't get the views it deserves
nope
Soild works lool take away there cad tools 🔧 is there anyone there that could wright a program of the top of there head like the old school operator's do still today i no guys that refuse point blank to waste time in cad will stand at the machine and program rgt of the top of there heads walking cad loool
To.much talking
the teachings are cool, but the video production is way over the top. please, dial it down a notch. it just looks like trash TV. the "walk and pan" shots are completely unnecessary and distracting. that's not to say you should do boring corporate videos, but the "IN YOUR FACE" big-buck TV production style is off-putting
