This drill is specially designed for stainless steel and other hard-to-machine materials. Made from premium solid carbide, it features reinforced cutting edges and optimized flute geometry to reduce cutting forces and ensure stable tool life, even when machining tough, low-thermal-conductivity stainless steels.
Features:
3 × D drilling depth → suitable for medium-depth holes with high precision.
Solid carbide construction → excellent strength, wear resistance, and extended tool life.
Special point angle (typically 140°) → ensures accurate centering and reduces thrust force.
Reinforced cutting edges → prevent chipping and provide stable stainless steel machining.
Optimized flute design → improves chip evacuation and reduces adhesion in sticky stainless steels.
Optional internal coolant channels → high-pressure coolant directly to the cutting edge for better cooling and chip removal.
Heat-resistant coating (TiAlN / AlTiN) → enhances wear resistance and minimizes built-up edge at high temperatures.
