Re: What kind of tap holders do I need for a Torq - Cut 22
Honestly I just use an ER collet and holder on #8 to 5/8 inch threads. Bigger than that I generally use a thread mill from LakeShore Carbide. I haven't had the best luck with smaller ones due to breakage and never had a job large enough volume to be worth the risk or effort to develop.

At that size I would also threadmill them. I do a lot of rigid tapping in collet and drill chucks for 10-32. I have found roll/form taps work well. It also depends on if you have a gear box or not. there were 3 spindles available, a direct drive, a high speed, and a high torque.

I think that is the high torque spindle. You could likely rigid tap that, no compression holder needed just get the code right. I would still use a thread mill if you are making several parts. Less problems and is likely faster.
