- This is a video showing how to make Tormach TTS-style tool holders using a CNC-converted Grizzly Super X3 Mill/Drill as a lathe. The holders are made from 1-1/2" diameter drill rod (silver steel), and cost about $5 each. Part 1 covers the basic setup and cutting the 3/4" shank; then turning the blank over and cutting the other end to make a perfectly concentric tool holder.
Part 2 covers the drilling of the hole for the cutting tool.
One of the best machining videos on TH-cam! The camera work and editing are first-rate, and the narration is informative, easy to understand, and well-paced. Just the right amount of technical detail, explaining what you are doing and why. Thanks for teaching us!
Thank you for this video! I wasn't sure what the gray riser was that came with the tool holder as seen at 4:18. Now I know it needs to be there as well as the insert tooling! Thank you
This is a great video and I am not sure how I failed to comment on it's professionalism the first time I watch this a few years back. Thanks for sharing! Your presentation makes mine look like child's play.
Awesome Video, I am going to try make a few of these just because you can never have to many tool holders :) Thanks for posting!
Great video, I've never seen a milling machine used to turn. I noticed the chips were very long; your speed and feed are off. You know you have the correct cutting conditions when the chips are shorter, usually around a inch or so. I Learned that from an old timer.
You did an excellent, very professional, job on making this video and the content is really interesting. Thanks
Great job!
I have Tormach PCNC 1100. To my understanding, the shoulder of the holder should be over cut. In that way, the holder shoulder contact the spindle nose directly, not the collet. If there is no over cut like in this video, TTS still works but the z offset of the tool will not be repeatable. This may not affect a manual work, but will make automatic tool change meaningless.
So I suggest you add the over cut to the shoulder of the holder.
I enjoyed watching this 🤠👍
This is very very cool. Thanks for the video! Well made!
@georgef8 I consider myself corrected - thank you for the information. We who learn in our garages sometimes need to be advised by those of you who really know what you are doing. Thank you very much for this most helpful comment.
Amazingly helpful video! Thank you!!!
@CncObsession Thank you for your comments. I, too, drew my inspiration from Hoss and his pneumatic drawbar for the X2. I think his manual adaptation for the G0704 is sheer genius! I find that it takes as little as .125 of travel to release the tools - I haven't measured it, but adjust the drawbar engagement in the Tormach collet until I get good holding power when released and easy extraction when depressed. I think I am using a stack of 6 Bellevilles that Hoss specified at CNCZone.com.
Absolutely - any lathe tool will work just as well in this application as it would on a lathe. The one thing is that is is sometimes hard to get a good approach angle unless you have a very pointed tool, but with some ingenuity you should be able to mount the toolbit appropriately for the cut you want to make.
Thanks for the kind comments - and keep an eye on this channel for info on a whole series of videos coming up - drawbar and lots more!
I just bought all the equipment to duplicate your work. Thanks a lot for the inspiration!
I really enjoyed this video. I could understand the prosess and actually see it being with an exceptionally clear explanation by yourself. Excellent. I'm planning on doing the conversion on my own Grizzley Deluxe X3 mill in the very near future. Did you make your conversion or purchase the parts to get it done. Would be be really great to hear from you about this as I'm considering thte Fusion Kit yet I would like to make the parts as well. Time will tell. Thanks for great videos, Lee
@devers6 I too learned in my garage and was also surprised the first time I read about gloves being dangerous around machines, but it makes sense once you think about it.
I'm in the process of making tool holders like yours on my X3. Instead of buying tool holders I decided to buy the tools to make the tool holders. In the end I'll have more tools.
I was wondering if you had any pictures or videos of the probe you made for centering, or of sharpie tool holder you mention. I bought some 1.5" dia delrin rod and I would like to make both tools from. I have some ideas on how to do it, but would be very interested in how you did it.
Great video! Thorough and instructive, and very well made.
I miss one thing, though - the recess that creates a separate ring to mate with the spindle. As mentioned in the TTS catalog:
"Each TTS holder has a precision ground shank and ring with a recessed pocket that eliminates collet interference. This design provides repeatable Z position and improves rigidity."
It would require a different lathe tool, however.
And lastly - who did you buy the lathe chuck from? Can't find it...
how about more on the pneumatic tool change. more interesting than the tool holders and mill turning
Making the same holders for my mill but have the advantage of a lathe what cutter inserts do you recommend for cutting silver steel, tried tungsten carbide but knocks the shit out of them quick
@mioduz I used W-1, solely because it was less expensive. I haven't machined a lot of drill rod, but I don't think that 0-1 or W-1 machine drastically different. I did not harden these holders after machining, so I don't think it matters much.
Good work, thanks for sharing the knowledge.
great videos i was wondering instead of a carbide indexable cutter could you use a HSS toolbit that you custom ground for that job? my machinist teacher told me to not use carbide for this kind of job because my g0704 doesnt have enough horsepower for carbide... but you clearly did it with your x3 so... would HSS work or not? im just looking for the most economical way and carbide is kind of pricey... Thanks and great vids again... looking forward to a drawbar video :)
Can you make a video showing how you made the pneumatic drawbar? or a video showing it and talking about it? Thanks
I know it's been a while, but please show your tool changer or add a link to a thread on a forum. I'd like to see it too.
Great videos, I didn't think it would be that easy to make those.
hey there, i'l got bandsaw just like that what blade did you use on this job
Great video. I just purchased a converted X3 and I look forward to making tool holders like you have detailed here.
I can't find any R8 lathe chuck adapters on ebay. Do you remember the seller you purchased it from?
did you use Oil or water hardened drill rod?
cool mods. for your viewers I'd suggest using pliers to remove the turning chips. they won't get grabbed easily.
Strange - at the time I made these videos there were R8 chucks everywhere on Ebay - I just checked and there seem to be none. I bought mine from a vendor called 800Watt, who had a mixed reputation for customer service but always worked out fine for me. A google search outside of Ebay didn't return much more, but I did find some at penntoolco and victornet for about what I paid. I wonder why they are so hard to find?
Great Video!
I have no problem sharing the G-Code - in fact I did so in a post on CNCZone soon after making these videos. Go to the Tormach group at CNCZone.com and search for a post named "Making TTS-style toolholders in a Mill/Drill". The G-Code can be found in post #8 of that thread.
I struggled as well trying to get a toolpath to make these using CAM software - I ended up making this code mostly by hand. It wasn't hard - mostly repetitive.
A beautifully done video - nice machining too. My only quibble is the advice to wear gloves for clearing chips at 6:18. That could turn a laceration into an amputation. The stick as mentioned next is the way to go. Here is an OSHA reference: osha.gov/Publications/osha3170.pdf
Great job！
Where is the video about the power draw bar?
thank you sir.
5:06 x+radius so can cut like radius lathe LOL and if not correct just move work offset VOLA
hi ya i would like to ask you for a copy of the gcode if you don't mind thanks a1 vid
No cutting oil needed for carbide, especially coated inserts.
you don't harden the drillrod?
You certainly could. I didn't bother because I didn't expect hard use from the ones I made. I expect that after hardening there could be some movement in the metal - might take a bit of grinding. A Dremel or die grinder mounted vertical to the table running while the spindle was turning would freshen up the inside diameter (or a toolpost grinder in a lathe). Outside diameter is non-critical but could be touched up to make it look better.
Great education, I am relatively new to CNC. Would you be interested in sharing the G Code for the "Tormach" home made tool holders. I would appreciate it as I am having trouble getting CasmBam to give me a G code at my knowledge level. Would appreciate your assistance here in Australia. With thanks. Lawrie
What you have to do is purchase a three jaw chuck that will take a threaded adapter, and buy an R8 adapter, same as what you do for boring heads..
my machine isn't setup for cnc yet. do you have the dimensions for the toolholder? get tutorial vids.
brian burns There’s nothing that says you have to use CNC to do these. If you are making just a few, manual works just fine. CNC really only adds the ability to make multiple copies quickly.
The great thing about these holders is that few dimensions are critical; just the 3/4 “ shank and the tool hole really. I remember mine being 1-1/2” dia at the shank end, about 2-1/2” long, with a holder dia just larger than 1”. A 1/2” 45 degree chamfer if you want. Then bore the tool hole as appropriate.
Good luck in your efforts!
5:00 Z+something
I don't find it surprising that a guy who coverts manual machines to CNC also takes 10 minutes to cut through 1 1/2 inch drill rod 😂😂
