Description

J245 thread mills for UNF threads (Unified Fine) are suitable for machine thread milling through or blind holes with right or left hand threads. They are manufactured from premium carbide material for superior performance and extended tool life in extreme conditions. The 10 degree spiral with coolant provides the strength and efficient cooling you need for high performance thread milling applications. A special Alcrona coating further extends tool life and improves performance when threading difficult to machine materials. For great efficiency, one J245 carbide thread milling cutter can produce any size thread with the same pitch.
