TOOL HOLDER: Erickson Standard Hydraulic Chuck Holder w/ Kennametal Hydraulic Chuck Reducer Sleeve. No Torque Wrench Required because it Bottoms Out when Tightening.
PS. Runout on the exit was less than .002
PSS. I programmed 1 set of holes and then just ran 3 times for the video. At first I was just going to do one hole... but thought I would add a few more just to show you the consistency.

so 0.0508mm in metric over 12" is pretty good especially with the tool life as well.
Hello Titan , do you hire people :D
Hello Titan. We have tested this drill dia. 12mm 25xD in 1.4301with Erickson hydraulic chuck vc 45m feed 0,11mm/rev 20 bar coolant pressure and the point of the drill got chipped after first hole. It was predrilled with KMT KU drill as recommended to 3xD and the procedure/ programming by entering the bore was correct. Clamping of the workpiece was similar to yours. Any idea for the cure?
@@ivanvarcek2814 the problem with stainless is that at work hardens. So if your drill is spinning higher RPM more than its feed you will get work hardening and it will become impossible for the drill to cut and it will break. So you have to have a higher feed and a slower RPM through all parts of the operation. Titan is also making sure to blow out the chips with the coolant before the long drill starts cutting
I love your video. How much coolant pressure in video?
I like how you are putting in a Metric conversion of your speeds now, I no longer have to do an automatic conversion from Imp to Met which is handy.
This drill may be useful for our company as we have just got a Mazak i400 Intergrex which is probably going to a fair bit of deep hole drilling.
Thanks for the video Titan.
then someone forget to remove the toolchange, and the automatical toolchanger breaks the drill.
**snap** .......oh no
Lol yes. Worked at a place where a drill got driven through the back of a brand new sl30. Ended up rebuilding the spindle
I love snapping drills, snappy was my nickname as an apprentice. I still snap drills to this day, lel x
anyone play these videos on 1.25x speed? old mate titan talks so bloody slow! maybe we just talk faster in Australia
It works 1.25x on this video as well. Some of his needs 1.5x. Despite I'm not native english...
Love the details in this video , never thought about the tip angle for pilot drills . Your walking on water brother ...
If so... it’s because of Him
@@TITANSofCNC praise be
really wanted to see what the surface finish looked like on that hole. very impressive drill regardless.
If I could get into the matrix this would be one thing I’d download the knowledge of haha. CnC is amazing
"Muterial"
I got a job as a machinist in a Cincinnati milacron 3spindle 5axis Gantry.. fanuc controls, any thoughts?
Hi Titan, did you measure the positional off-center error of the outgoing hole? Which minimum error can I specify on the drawing, without driving you nuts?
I'm wondring too :) What was the off-center error at the bottom exit?
"Runout on the exit was less than .002"
@@nonjb3811 though related, run out does not translate one-to-one into off center error
@@kunstderfugue sure it does. Why doesn't it?
@@gt40f If you think about what happens to a drill in slow motion, what run out does to it is it makes it bend "in all directions*. The effects primarily mean two things:
1) Increased size of the hole. In simple terms an increase in run out distance equals an increase in hole radius (or 2x increase in diameter).
2) Increased wear of the drill as it constantly hits against the wall. I don't recall the exact amount (you can reference it from the Sandvik E-Learning course on drilling) but something like 0.01mm of run out generally means half the tool life.
Off center error, however, is something different entirely. The hole might be the right size, but it's not in the exact spot you want it. Run out of a drill might contribute to a hole being out of tolerance, but the off center error can be caused by other factors.
Anyway, I hope this helps a bit. I haven't machined for super long so I could be wrong, so I encourage anyone to contribute with empirical evidence and theoretical information. Cheers!
P.D. Maybe we can get Titan to opine on the matter. He's the real expert here.
Hey Titan, I'm in the automotive plastic injection tool industry. Sometimes we get situations where we're roughing or finishing oddly shaped lifters and slides that are decent size. A lot of videos showcase very small shapes or low complexity operations. I'm wondering if you could make a video showcasing a longer style rougher and/or finishing cutter on P20 steel. Some new tech getting hard to reach areas with accuracy and efficiency. Thanks!
Hmm 🤔
This is a great idea.
I use mitsubishi feedmill
Plot twist:
The coolant holes drilled through your drill are even more amazing.
But they are extruded through bar stock and the drill flutes are ground around the twist rate of the holes.
@@jonathanpowell4627 Ah! I was wondering how they did that. I was thinking "Holy Fuck that'd be an insane hole to drill through that bit safely!" Lol
So you're saying they actually take bar stock with the hole already in it, THEN create the flutes and etc around it. Got it. :)
@@jonathanpowell4627 What do you mean "extruded"? How are they created? They have to be drilled as well right?
Maybe from both ends? Or they'd need a 100x diametre drill.
Titan
I have a request on behalf of whoever having the same query
Can you make a video for that.
Materials range and code description for tooling
Tools flute helix angle relate to machining part material?
Google Sandvik E Learning, do the course and it teaches about workpiece and tool material grades along with a bunch of stuff. Then do the course on academy.titansofcnc.com and you'll be one happy machinist :)
I'd like to see a video on feeds and speeds. I'm new to machining and my biggest problem is finding out the fastest my mill can cut mild steel with a max spindle speed of 2500 rpm. So many variables, material, type of tool, number of flutes, rigidity, spindle speed, motor hp. Etc...
Serious question. How many drills did you break before you found the perfect speeds and feeds?
Tyson nice stuff I have done many many deep holes with another brand . 2 important things really need to drive home
a) Coolant 100 % important and pressure in the early days Y2002 chip removal and coollant type major factor on horizontal machine.
Causing breakage in TI switched to Vasco 1000 no breakage better flow no heat at tip or traped chips also program slight dwell allowing HP
Pump to kick in
b) Tool change if have option for tool type during tool change make sure you use heavy tool option on smaller tools 3mm and below
in some cases on horizontal machines the force of tool change can cause tool breakage.
That said hope helps some nebees enjoy.
Edit: just saw the updated pinned post referencing .002 run-out at exit.
Original question: What is the lateral deviation from start position to exit hole? Is it truly 'perfect'? Or under a tenth? I've always had trouble with small amounts of wander but these drills look wicked cool. Even if you're a tenth off over 12 inches that's well within what I'd need. Checked the link you provided and while expensive, I think these drills look to be the ticket.
Thanks for another awesome vid.
I love that sound when the drill winds up and starts making chips. We use this kind of drilling for waterlines with the molds we make. We drill into aluminum so we wind that sucker up and just plow through the material. Takes less than 10 seconds to drill a hole 11 inches deep.
Awesome. We do a lot of 20xd on our lathes. My butt puckers every time.
Hi Titan, your videos are very helpful, is there any chance you could do a video for machining duplex and super duplex like you have for inconel, hastalloy, monel etc?
Will put it on the list.
Duplex is tough but easier than my A286 videos so if you start there and then increase speeds... you will be good
We use the exact same drills on tool steel. The guys don't know how to utilize them very well so it doesn't last. From a diameter 5 to 15 they just break like twigs.
What?
Ya, it’s all technique... surprised they are breaking. They need to ask for help
@@TITANSofCNC whenever we get new tools, our tool rep comes in and works with us on speeds and feeds until we are satisfied with the results. John-peter Kivedo have whoever is in charge get a tool rep in your building .
Gotta love thru spindle coolant ....
Been marching 36 years fist time to see this amazing job glad I came by this channel great info
It would be nice to see how much did the drill walk, and it if the upper diameter stayed the same.
very minimal, if carbide walked too much it would snap
@@rick371 you might be surprised how much a drill that long can bend without snapping.
I filmed it but the video was already long. It was within .002
. 002 is nothing over that length
@@rick371 that lenght has a tolerance about + - 0.3 so yeah
no wonder
Can you do a similar videos on micro drilling? I often have to do .025"-.032" holes in 316 to a depth of over 15 times the diameter. I've had trouble getting reliable feeds and speeds and end up breaking bits off in the hole. As a result I started doing that feature on my micro drill press by hand. Good video. Please keep it up.
Check out Mikron drills. I've done .040" x 15xd
Did you have to hand load the drill due to it’s length?
Yes
We have a 14mm diameter x 100 drill, it's not fun...
@mondayfool We have to aim the coolant over the top of 4 different plates to reach the end of the drill which is hand loaded into a pre drilled hole, luckily it's not drilling that deep only 30mm
Hi I have issue with step drilling tool which found oversize in auto cycle after remove tool and clean tool and spindle then diameter is on the mean.
Did you check your spindle through
I faced some problem while drilling HSS drill in STAINLESS STEEL material
Chip breaking issues as well drill overheated
Vc=20m/min
F=0.1mm/rev
It really worst case with SS
So. How was the tolerance from top to bottom ? Did it go straight thru ? Always seems to be the problem when drilling with long drills.
How is the coolant line made? Through extrusion of the blank or using an even higher ratio drill?
most likely edm
@@mannycalavera121 do you mean edm?
EDM = electric discharge machine; uses electric current flowing through a tool bit to remove metal from the work piece. Good for cutting complex shapes as the removed metal takes the shape of the bit.
I do holes like this all the time in 316 on a manual machine.. altho this is cnc i still learned some helpful tips. Thanks, great video!
Hi there, I'm pondering if I should do something like this on my Bridgeport or if I should send it to a shop that has coolant thru capabilities, can you share your experience on a manual machine?
Titan I was wondering, does a person get anything showing that they did or has taken your courses?
New certifications platform coming called CNCEXPERT. By the end of the year
TITANS of CNC: Academy Awesome thanks for the reply. My job has us pick goals for the year and I want to learn more from you and your courses. Thanks again!
Hey Titan, thanks for sharing another great video.
Now wouldn't this drill qualify for a Abom79 badge? Well, at least for CNC side of things :)

what if you have to drill throgh a 70 inch long part I suppose that then you will drill for 38 times the diameter (I left 2 for safety) and flip the part or rotate the c axis and drill the rest but my concern is in the break through the non plane surface won't that cause any problem?
Kennametal makes specials beyond 80X deep. Definitely would have to be on a different machine with a greater work envelope and then I would attack it from both ends, meeting in the middle to ensure rigidity and success.
Sod that, would rather use HSS and take my time. If that carbide drill breaks down a blind hole you are screwed if the broken part is stuck down the hole, pretty much only way to get it out is spark erosion. Frequently do up to 100xD holes and never use a pilot hole either. At my work we go for the quickest to program as usually just machining 1-6offs. If we get big repetitive orders we would speed things up or used to just run another machine at the same time.
Perforar agujeros de diámetro pequeño a gran profundidad, es simplemente una pesadilla. RPM y dureza del material,. Encontrar el punto preciso dónde no se rompa la broca es todo un reto..... Wow.
tomorrow I will be drilling some 0.12 mm holes on a 24000 rpm spindle mounted on manual milling machine! It's high precision and sensitive...and I have no ideas about the holes I'm going to drill and how to engage!
According to the screen, the IPR for the long drill is actually still .003 inches, because BOTH feed and spindle speed are now at 10% those of the pilot drill. Thanks for making these awesome and inspiring videos. Also I’m curious about if there is a way to turn off side coolant and turn on through coolant during the drill cycle, or if it was done manually.
I am interested also... right now, I would have to interrupt the program.
But it works because it gives me a pause before I drop deeeeeep
why does this drill bit drill a million more holes than GOdrill?
Backing up statements with why that is would be cool.
like, it can drill a million more holes because you can keep sharpening the tip and it has so much length it will take hundreds of sharpening before it is a useless stubby bit?
What about grinder machines and everything involved with them?
That was damn cool! I love these videos!
Llevo más de treinta años ganándome la vida mecanizado piezas. Muchas de ellas bastante más complejas de las que este tío presume.

Por qué no tienes tu propio canal entonces? / You don't have to follow Titan if you think he is fake.
Some very interesting techniques your company makes use of, brilliant work there too! I'm trying to learn more CNC and never fail to find more to see. Subscribed 👍
Its hard to stress the being careful about chip build up at the top of a hole in stainless enough. I've always wanted to program a macro similar to g83 but for stainless. With smaller machines without the hp the chips get stringy and if the rapid is at 100% you can run into problems with chips at the top of the hole while reentering the material. The only way to fix that is to put rapid at 25% or program a subprogram.
I often go as deep as possible without peck and then pull back just .005 and dwell for a second, this keeps chips away from the cut surface and allows the material to cool etc. then I keep going and repeat. Trick is to have feed to break the chip.
@@TITANSofCNC yeah it's easy to break chips with larger hp machines. Staying in the cut is a rule a great rule of thumb for any operation in stainless.
Estas brocas con el afilado a 140 grados en ángulo de punta son un producto de la antigua Empresa Hertel Alemana
For Drilling such holes, probably EDM is a better and more accurate solution … but of course a little slower.
Thank you!! I'm teaching my wife how to run my custom built mill with these videos.
Love ur channel just the way you talk and make sure your words are super clear kills me
Sharing this information is great but for those of us that do NOT have TSC, & exotic tooling.. Can this be done another way ?
Titan.
Would you ever consider offering your training tool kits to people in a hard spot trying to get themselves up to the next level?
All my academy.titansofcnc.com is FREE and I don’t take a cut from Kennametal’s Kits as they are below cost to make them
Thank you for a response, and I appreciate you time and all you do. I am going through your curriculum with 16yo son. I Have been programming and operating for 15 years. I pick up something from every video and lesson. Learned manual machining 20 years ago while serving 2 years. 4 months ago my leg was run over in a parking lot. I am almost able to walk again and get back to my smaller manual and CNC machines in garage. I was in process of purchasing Haas tool room lathe and mill when hit. Down payment and credit is now gone. I had a 5 year goal to have aerospace milspec job shop. Offering high school kids apprenticeships. I'll be back to where I need to be in a year or 2 maybe less financially. I'm sure I'm not the only one who is in a similar situation. You do more than anyone else in the field I have seen to promote the industry, I know you give A LOT already. IDK maybe a show me your shop contest. Sorry for the ramble on. Keep it up.
I use GUHRING 40 and 45xd drills in 6.3mm dia in the OEM automotive mfg field. I've made some improvements on the typical deep hole drilling cycle for increased efficiency. CODE BELOW.
I also don't engage nearly as deep OR as slow. I drill over ONE QUARTER MILE of material with drills like these before sending out for resharpening at the manufacturer.
.400" of pilot depth
.300" of drill engagement, enter piloted hole at 20 IPM/400 RPM and don't turn the 1100 psi TSC off when entering or exiting holes since it does not affect how the drill enters the pilot hole at all.
Using regofix holders I have a few tenths of runout at 12 inches of length on my Okuma M560V's.
I feed and retract in G1 to prevent the momentary Z axis stop at the bottom of BLIND holes which causes extreme edge wear as the tool unloads and "whips" but there is one thing that really improved efficiency:
(in G1 mode) I program so the machine feeds down to hole bottom, once at hole bottom I command the machine to feed up to the -.300" pilot engagement point WHILE SIMULTANEOUSLY slowing the spindle down without looking for spindle speed verification before moving to the next block- this makes it decelerate at hole bottom, then re-accelerate into retraction while simultaneously slowing the spindle so the drill doesn't whip around at hole bottom as it's unloading from Z force and slowing down in RPM. Once it reaches the engagement point I have it verify that the spindle RPM's are back down to 400 before pulling out of the hole which usually does not require the Z axis to stop moving except on shorter holes so movement is very smooth throughout the whole cycle. Not every controller is capable of such fine tuning but I was able to set this all up in my custom post processor.
Those small tweaks shaved seconds off of cycle times and increased tool life significantly comparing to just G00 rapiding out after slowing the spindle down at hole bottom.
Some materials may warrant edge radius modifications to the drills, such as cast iron* (high perlite content) and other gritty cast materials. Special drills with edge radius DOUBLED my tool life in cast iron.

Do you dwell at the bottom of the first hole to ensure a perfect nice surface for the 40d? Thanks
Yes, 1 second
Are you guys fans of using spindle overload warnings while testing out these tools?
Hello I am looking for Drill 0.5 mm to 3 mm length 300 MM . Please guide
THAT is ONE very LONG sword u got there MR, TITAN
According to Novo Kennametal for this drill feedrate is about 10 times bigger and cutting speed as well for stainless. Vc 40 m/min and Vp 127.36 mm/min. Titan Could you explain why did you go down so much?
Ever considered making a Curta Calculator?
Can someone explain to me how to create a really long injection molding barrel.
Is that still good for copper? At work we’ve got a project requiring cooling channels deep into copper.
I haven’t in copper but would definitely think so. Use the Super Alloy version and take a few test cuts to ensure your feed is cutting small chips... etc. I have done it in Monel and that is tougher than copper as it has 33% copper and 60% Nickel
Yes. very easily
I'd like to see a video for drilling 17-4ph H900. Ive been told it should be treated like 4140 at ~30HRC
do an episode on deep boring. 8x diameter bore with a 2" bar... "What?! no, I dont need to do this... just want to see how you would do it..." lol
Hey titan, try these www.iscar.de/Products.aspx/countryid/7/ProductId/71 "onelip drills" up to 400times diameter these work perfectly fine even in stainless and other hard materials
Can use these drill bit on cnc turning center with main spindle rotation?
Would be interesting to flip the part and measure the far-side true position of the holes to see how much the drill may have wandered. $0.02
What's next 40xD in tungsten?
How would you go about drilling a through hole in O1 tool steel with drills under an 1/8th going over 20x Dia?
Titan, have you ever used TX drills?
17-4 PH is the capital B for deep drilling, especially for no coolant through drills.
Thanks for video, Titan. We will use this example for drilling calibrator tool on DMU070
Anybody else want to see the process of making that bit? Mostly the coolant passage through it has me curious on a bit that long.
Kennametal has a 72 x D diameter lenght drill called HP drills, would you ever try it?
How was the wandering? How close to true position was held?
.002
Too much talk and warped talk is annoying af.
Could u show us all the different materials what they are called tensile strengths and the different bits used for milling pls
Damn that is satisfying, especially when you've drilled holes like that by hand.
High speed m6 tapping in duplex
It’s weird that you don’t have to worry about deflection screwing up your tolerance.
You should do a video about small diameter gun drills and trick to keep them straight.
Is there anything better than through spindle coolant
Depending on material, through spindle straight oil might be better.
How come you didn't drill the 3 pilot holes first before 40x dia drill holes?
Titan, programed by manual movements or any G code canned cycle?
I do it manually because I like to make adjustments that can’t be done in CAM.
Here is a video where I explain the code. ruclips.net/video/3B_w1asSGzM/видео.html
What kind tolerances can this drill produce?
Well, that was new to me! The way they move into the pilot makes soooooooo much sense! I´m gun drilling plasctics on my haas lathes and i think, this video gave me a proper way for straight borings anyway! Thanks for that! :)
I want to see them (manufacturer) drill this drill for through coolant! Crazy! Someone gave a video for that?
if i don't have a thru coolant drill, can i use the same method as what you showed??
Love drilling ma253 stainless
What if that dia is .060 you peck it though 🥴
And our cnc guy can't drill a 8mm hole 8cm deep without 1-2mm runout in aluminium lol
Give him the right tools
couldn't the 3 pilot holes be done in one pass ? that would have reduced tool changes
Hey Titans on cnc team do yall have experience drilling incoloy 901?
now it just went down for real today folks nothing like deep drilling and thats what she said !!!!!!
Do you have a videos on learning G-Code?

I've been using Walters 6mm 50d, it's a beast.
That’s Awesome! I used Walter Titex and Guhring + for 20 yrs... This SGL is so much better... also, the others has a single drill for everything... Kennametal SGL comes in 3 different types... so the one for Inconel is different than the one for Stainless and blows other drills away when it comes to number of holes drilled.
I've been using this one as well. Its almost comically fast in mild steel, just punches holes in steel as if it was cardboard.
I hate stainless steel lol
I love your passion! Great videos!
Oh man, if I could only drill a 20” barrel with that
That IS awesome!
Yes , but do you dwell when switching stages ? , and how much
