Sandvik Coromant’s light cutting insert for its CoroMill 170 precision gear milling cutter reduces cutting forces, making it a good option for small gear milling machines, giving users the option to reduce power consumption or run faster and longer.

The insert features a positive chipbreaker that minimizes unwanted cutting forces and vibration. This helps produce less heat generation in the cutting zone and prolong insert life. In tests, the -PL geometry shows 20 percent lower power requirement when the maximum chip thickness is less than 0.004 inch.

Taking advantage of Sandvik Coromant’s grade GC1030, the technical features of the insert support improved cutting stability, and in turn, allow high cutting speeds. Working in the steel application area, typical operations include rough milling of internal and external gears, along with the machining of large gear wheels in the 12-22 module range. Sandvik Coromant recommends a lower feed than used for existing CoroMill 170 insert geometries such as -PM (medium) and -PH (heavy).
