Product strengths:
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 drill bits.
TiN coating has a hardness of approximately 80 HRC and is very wear resistant.
TiN has a low coefficient of friction, which means 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.
Warranty coverage: No warranty.
