Arbor, Slitting Saw, Tormach TTS

The arbor locks into the TTS collet securely with zero wobble, making blade swaps quick and simple. I’ve been using it with slitting saws for precise cuts on mild steel, and the grip is rock solid even under heavy feed.

Fits the TTS collet system without any adapters, and the threads are cut clean so the blade seats square every time. I’ve used it for a few dozen cuts in mild steel and it hasn’t loosened once. Exactly what I needed to add slitting capability without swapping out my whole setup.

The TTS mounting is rock solid—zero runout when I checked it with a dial indicator after torquing it down. The blade seats flat and square, and it’s been cutting clean slots in aluminum all afternoon without a hint of chatter.
