Leitz says its ProfilCut Q polycrystalline diamond (PCD) profiled insert system accurately maintains diameter and profile and has approved cutting speeds of 120 meters a second. Diamond tooling features safety locked inserts which cannot move under centrifugal forces, and secured PCD knives offer at least 20 times the service life of carbide inserts according to the company. Available in a lightweight aluminum or steel design, ProfilCut Q PCD can be adapted for use with virtually any machine application.
