IRWIN IRW10502574 TiN Coated & Cobalt Jobber Drills

General description The Irwin HSS Pro TiN Coated Drill Bits are designed for precision drilling in metal and tougher alloys. With a size of 2.0mm in diameter and an overall length of 49mm, these drill bits feature a 135° split point grinding tip that ensures perfect centering and reduced drilling pressure. The high-quality HSS steel body is coated with 2.5µ Titanium Nitride (TiN), providing exceptional hardness and wear resistance. Technical specifications Overall Length: 49mm Tip Diameter: 2mm Working Length: 24mm TiN Coating Hardness: approx. 80 HRC Usage The Irwin HSS Pro TiN drill bits are ideal for drilling into metal and harder alloys. Compared to traditional HSS twist drill bits, these can increase drilling speed by 40-60% and feed by 10-20% without significantly reducing the lifespan of the drill bit. The TiN coating helps to divert heat generated during drilling into the chips and coolant, reducing heat buildup in the drill bit itself. Other information
