Walter's WKV10 and WKV20Click image to enlarge

Walter has added two new cast iron insert grades to its Perform Line family of turning tools, the WKV10 and WKV20.

These new negative geometry grades are ideal for machining small or medium batch sizes. These new grades in the Perform Line supplement corresponding grades for steels that were introduced last year.

Along with these new grades for cast iron, Walter has also introduced new positive geometries FV4 (finishing) and MV4 (medium). These geometries are primarily designed for steel and associated with WPV10 and WPV20 grades.

These inserts are an option for users who have difficulties measuring the tool life of an insert and who change inserts at set intervals. Both WKV10 and WKV20 grades have extremely wear-resistant CVD coating and can be used for a wide range of materials and applications.

The new grades are available in two geometries: MV7 (medium machining) and RV7 (roughing). Primary application for these new Walter Perform turning inserts are cast iron (ISO K).

In field testing, the Walter Perform turning inserts have demonstrated superior process reliability with very good chip control, and tool-life increases of up to 100 per cent when compared to other similar inserts.
