Description
Robust drill design and optimised special point geometry for the best possible chip formation and reliable chip breakage with higher feed rates at the same time.
Advanced micro-geometry, convex cutting edge and conical profile grinding provide additional stability for the main cutting edge.
Optimised flute geometry and patented face geometry for reliable chip evacuation in steel materials and cast material.
High-performance coating of the latest generation.
