Sign in to view price and availability

The HEPYC 11750 series features solid carbide (HM) drills manufactured to DIN 6537 standards, designed for high-performance drilling in high-strength steels, stainless steels, cast iron, and titanium alloys. The 140° point geometry provides excellent self-centering, improved hole accuracy, and reduced cutting forces, while the 30° helix ensures efficient chip evacuation for stable machining.

Manufactured from solid carbide (HM K20–K40) and coated with TiAlN, these drills deliver exceptional wear resistance, high-temperature performance, and extended tool life in demanding CNC machining applications. The 3×D drilling depth makes them ideal for precision production with maximum rigidity and reliability.
