IRWIN HSS Pro TiN Coated Drill Bit Set, 1.0mm

The IRWIN HSS Pro TiN Coated Drill Bits are precision-engineered for drilling metal and tougher alloys, offering superior performance and durability. With a titanium nitride (TiN) coating, these drill bits allow for increased drilling speeds (40-60% faster) and feed rates (10-20% higher) compared to standard HSS bits, without significantly reducing their lifespan.

The 135° split point grinding tip ensures perfect centring and reduced drilling pressure, making it easier to start and maintain accurate holes. The TiN coating, with a hardness of approximately 80 HRC, provides excellent wear resistance and a low coefficient of friction. This reduces heat buildup and power consumption during drilling, while the coating's poor heat conductivity directs heat away from the drill bit and into the chips and coolant.
