Higher process reliability through coating and grade

The combination of the Tiger·tec Gold coating and the WMP20G cutting grade delivers consistent edge protection under higher temperatures common with stainless steel. Coated carbide substrates reduce friction and delay wear, which translates into longer tool life and fewer interruptions for tool changes. For production environments this means improved uptime and more predictable component quality.

Predictable chip control and surface quality

The MM4 chipbreaker is optimised to manage the chips that form when turning stainless steel, reducing the risk of built-up edge and promoting steady material evacuation. A stable chip flow helps to maintain tool engagement and supports reproducible surface finishes, decreasing rework and ensuring components meet tolerance requirements with less inspection effort.

Accurate geometry for repeatable performance

A 16 mm triangular plate with a 60° included angle, a 0.8 mm corner radius and a 7° relief angle provides a balance between robustness and cutting precision. The modest corner radius gives strength for interrupted cuts while still allowing fine-detail finishing where required. These geometric parameters support process stability across batch production and one-off runs.

Application guidance and machining advantages

This insert is intended mainly for stainless steel under medium to robust cutting conditions. The coated carbide chemistry of the WMP20G grade supports safe chip formation and good edge retention. For set-up recommendations, match feed and speed to the component OD and material condition; the combination of the Tiger·tec Gold coating and the MM4 chipbreaker reduces the likelihood of workhardening and enables efficient machining cycles.
