Hunter’s brake lathe tool holders allow techs to switch cutting inserts on-the-fly during machining. The dual-tool design accepts both an exclusive micro-round .0125” insert on one end and a 0.060” nose radius, positive rake insert on the other. With a quick flip of the holder, the tech can apply the appropriate cutting tool to maximize productivity and ensure a superior finish regardless of the size or material composition of the rotor. The new insert holders are supplied standard with all OCL410 on-car rotor lathe models.
