Waukesha, Wisconsin-Walter's indexable turning inserts are designed for applications that require soft cutting and high precision. This is achieved through the FP2 geometry, which is a high positive (18°) rake angle geometry with soft honing to ensure reduced cutting forces and vibration trends. High tool life is achieved through WEP10C coated cermet material with multilayer TiCN TiAlN PVD ​​coating and fine cermet micrograins. The combination of edge treatment and grade also ensures long-term dimensional stability, thereby increasing the productivity of mass production.

The new FP2 geometry also uses "negative tolerance" or "maximum fillet radius" tolerances. This allows for a stronger corner radius than the standard ISO/ANSI corner radius. For example, to machine a shoulder with a fillet radius of 0.0157", an ANSI-0.5 fillet radius (0.0078") is usually required. However, for FP2 geometry, 1M tolerance (equivalent to ANSI 0.0157" but 0.0146" ±0.0008" tolerance corner radius) can be used. The advantage is that a stronger corner radius can extend tool life and improve the surface finish of the same machining. The new insert is very suitable for finishing thin-walled parts, small diameter parts, long parts, parts with unstable clamping, and fine boring applications.
