TOTIME3839 Series

Variable Lead Roughing Carbide End Mill for General Steels, Cast Irons

Features

●Suitable for rough machining of ordinary steel and cast iron materials (≤48HRC) with large cutting depth and large cutting width, with high metal removal rate.

●The design of dense teeth and wave teeth with unequal helix angle produces ultra-fine short chips during processing, acheives excellent chip removal performance, low cutting resistance and low machine load.

●Special edge treatment, effectively improve chipping resistance and wear resistance in the roughing process.

Shape type
