Irwin IRW10502574 TiN Coated and Cobalt Jobber Drill Bits 2-Pack 2.0mm 49mm 24mm

The Irwin HSS Pro TiN Coated Drill Bits are designed for precision drilling in metal and tougher alloys. They have a 2.0 mm diameter and 49 mm overall length, featuring a 135° split-point grinding tip that ensures centered starts and reduced drilling pressure. The body is made from high-quality HSS steel and coated with approximately 2.5 µm Titanium Nitride (TiN), providing wear resistance and hardness. The TiN coating helps divert heat into the chips and coolant during drilling, contributing to steadier performance and reduced heat buildup in the bit. These bits are suitable for drilling metal and harder alloys, with performance improvements over traditional HSS twist drill bits.
