حامل قاطع الطحن، Tormach TTS، 12 مم

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.

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.

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.
