Solid Carbide Drill DIN 6537 – Series 11780 (3mm - 20mm)

The HEPYC 11780 series features solid carbide (HM) drills manufactured to DIN 6537 standards, designed for high-performance and precision drilling in demanding machining applications. The 140° point geometry provides excellent centering and stable cutting performance, while the 30° helix ensures efficient chip evacuation and smooth cutting.

Manufactured from integral solid carbide (HM) and featuring a TiAlN coating, these drills offer excellent wear resistance, high thermal stability, and extended tool life. With an 8×D drilling depth and internal coolant, the 11780 series is designed for deep-hole drilling and demanding CNC machining applications.
