Walter USA has introduced two insert grades in its Perform line of turning tools, the WPV10 and WPV20. They are designed to be versatile, cost-effective inserts for users whose machines are limited in cutting parameters due to stability and performance, and who need a versatile insert that can handle different materials, as well as for those who machine small or medium batch sizes. The inserts are also beneficial to users who have difficulties measuring the tool life of an insert and who change inserts at set intervals, for example at the beginning of each shift.

Both grades have CVD coating and gold color for easy wear detection. They are available in three geometries: FV5 (finishing), MV5 (medium machining) and RV5 (roughing). The primary application for the inserts is steels (ISO P), with secondary applications in stainless steels (ISO M) and cast iron (ISO K). In field testing, the company says the inserts demonstrated superior process reliability and good chip control with tool life increases of up to 100 percent when compared to similar inserts.
