Kyocera Industrial Ceramics Corp., Cutting Tool Div.'s MFPN facemill accepts PNMU inserts, which have a double-sided, pentagonal design that provides 10 cutting edges per insert. The combination of the tough, dual-angle edge and the 10° positive axial rake angle allows the facemill to run at a high feed rate, according to the company.

facemill
Milling cutter for cutting flat surfaces.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- rake
rake
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
