IRWIN Bit HSS TITANIUM Ø4x75 mm

- Split point of 135 ° rectified. Ensures perfect centering and reduces pressure during Biting;
- Industrial grade rectified groove for maximum precision Biting and quick removal of debris;
- High quality steel body with titanium nitride coating (TiN). Resistant to heat and friction, offering life up to six times longerthan normal metal Bits. The TiN coating has a hardness of about 80 HRC and is highly wear resistant. TiN has a very low coefficientof friction. As a result, it consumes less energy and generates less heat during Biting;
- Speed ​​and power compared to traditional HSS helical Bits, speed can be increased by 40-60% and power by 10-20% without significantly reducing the life of the Bit bit;
- Less heat. TiN is also a very weak conductor of heat, so the heat generated during the Biting work is derived from the debris andcoolant, while the Bit absorbs less.
