Product details
135° point with cross-grinding for perfect centering and less drilling pressure. Industrial spiral flute for high-precision drilling and fast chip removal. Body made of high-quality steel with titanium nitride coating (TiN). Heat and friction resistant, up to 6 times longer life than standard metal drills. TiN coating has a hardness of approximately 80 HRC and is very wear resistant. TiN has a low coefficient of friction, which means that less force is required and less heat is generated when drilling. Compared to traditional HSS twist drills, the speed can be increased by 40-60% and the feed rate by 10-20% without noticeably reducing the life of the drill. Titanium nitride is a poor conductor of heat, so heat generated during drilling is dissipated into the chips and coolant rather than into the drill bit. Up to 6 times longer life than burnished alloy steel.
