William ★★★★★

Swapped out my old collet setup for this TTS holder and the quick change is a game changer for tool changes. The 3/8" bore grips my Weldon shank end mills securely with zero runout that I can measure, and it’s held up through some aggressive cuts without any loosening.

Alexander V. ★★★★★

The Weldon flat seats perfectly in this holder with zero play—my runout dropped noticeably. It's been solid through several roughing passes on steel without needing to retighten.

Violet ★★★★★

The 3/8" shank seats snugly and the quick-change action locks without any wobble, which is exactly what I needed for swapping tools between operations. Ran a few passes on aluminum with a Weldon-shank end mill and the grip held firm the whole time.
