DrillMeister DMH -Wheel hub bearing-
IMPROVED TOOL LIFE AND PRODUCTIVITY
The DrillMeister DMH151 demonstrated outstanding performance in the mass-production drilling of S50C wheel hubs. Compared with the existing solid carbide drill, tool life improved by 70% while productivity increased by 22%. The test proved that DrillMeister can successfully deliver longer tool life, higher productivity, and lower manufacturing costs simultaneously in high-volume drilling applications. The DMH head, featuring a reinforced cutting-edge geometry, provides extended tool life, especially in through-hole applications, as demonstrated in this practical example.
