Quick change Tormach 1/4" set screw tool holder for end mills and other milling tools.
Tormach screw holders are suitable for general milling operations and are intended to be used with end mills that have a Weldon shank (flat surface on shank). They can also be used with certain Silver & Deming style drill bits.
The tool holder has a set screw on one side and a balancing dimple on the other side. The balancing dimple reduces vibrations at speeds above 8000 RPM.
See Chris' Tips regarding centering of end mills when using a set screw holder.

Customer Reviews (4.6 / 5 · 5 reviews)

Amelia ★★★★★

The set screw locks down my 1/4" end mills firmly with no wobble during cuts. Swapping tools takes just seconds now, and the whole thing feels solid on the TTS mount.

Charlotte ★★★★★

I swapped this onto my Tormach mill and the quick change is smooth—no more fiddling with collets for standard 1/4" end mills. The set screw grips tightly enough that I've had zero chatter during light cuts.

Daniel ★★★★★

The set screw design gives a really solid grip on the shank, and it's nice that the TTS shank makes tool changes quick. I've had no runout issues so far in a few aluminum jobs.
