Quick change Tormach 12 mm 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.

Adam X. ★★★★★

The 12 mm bore is a perfect snug fit for my end mills, and the set screw holds them securely with no slipping during cuts. Machined finish is clean, and it's been solid on my mill.

Nicholas ★★★★★

The set screw locks my 12 mm end mills down tight with zero runout, and the quick change TTS shank makes swapping tools between jobs a breeze. I've put it through a few aluminum runs and it holds position perfectly every time.

Edward Y. ★★★★★

Swapped out my old wrench-style holder for this set screw design and the quick change aspect alone saves me a solid minute between tooling swaps. The 12mm shank seats snugly and hasn’t budged through a few rougher passes, which is exactly what I needed for repetitive milling jobs.
