MRW

Economical and high efficiency radius cutter

with double-sided insert for various types of workpieces

Economical double-sided 8-edge insert

Combine sharpness and cutting edge strength

Obtuse edge increases cutting edge toughness

Helical cutting edge design with maximum axial rake 12˚ reduces

cutting force, equivalent to positive inserts.
