The WALTER square turning insert is used for general turning, facing, and profiling operations on steel, stainless steel, and cast iron workpieces. Its RK4 geometry provides a sharp cutting edge for low cutting forces and good surface finish in medium machining applications.

Select the insert geometry based on material group and operation. For steel turning, the WALTER RK4 geometry with a positive rake and sharp edge reduces cutting forces and built-up edge. Match the insert size (SCMT433 or SCMT120412) to your tool holder's pocket and your depth of cut requirements.
