Maximum surface quality with maximum productivity – our new turning insert with wiper geometry
Compared to conventional turning inserts, the wiper version offers decisive advantages: thanks to its special geometry, the contact area with the workpiece surface is extended, resulting in significantly improved surface finishes – all while maintaining high feed rates.
What this means for you: shorter machining times combined with excellent surface quality – often eliminating the need for additional finishing operations such as grinding or polishing. Ideal for applications where precision and efficiency are equally important.
Experience the perfect combination of dimensional accuracy, long tool life, and increased productivity – with our wiper insert for modern machining processes.
