Walter’s Tiger-tec Silver turning inserts are designed to reduce machining times and increase process reliability, particularly in steel turning applications, the company says. The Tiger-Tec Silver CVD coating is said to increase productivity while extending tool life. The inserts are suitable for use with unalloyed and alloy steel, cast steel, stainless ferritic and martensitic steel, as well as ductile cast iron.
Of the three grades, WPP10S offers the highest temperature resistance and hardness. It is wear-resistant and suitable for processes ranging from continuous cutting to minor interrupted cuts at very high cutting speeds. WPP20S, the medium grade, is suitable for use as a universal cutting material for processes ranging from roughing to finishing. WPP30S maximizes reliability for difficult applications such as interrupted cuts and unstable conditions.
Four geometries are also available. For facing and light cuts, the FP5 geometry is said to provide reliable chip control during turning operations from 0.008" depth of cut. The MP3 geometry is suitable for medium machining, the versatile MP5 geometry is specifically designed for general machining and the RP5 geometry is designed for roughing.

Toolholders with integrated cutting fluid delivery channels offer threaded, fixed-position nozzles that direct parallel streams of coolant to pre-defined positions at the top of the cutting tool.
