Irwin HSS Pro TiN Coated Drill Bit 3.5mm OL70mm WL39mm IRW10502580

General description The Irwin HSS Pro TiN Coated Drill Bit is designed for drilling metal and tougher alloys, offering enhanced durability and performance. The drill bits are coated with titanium nitride (TiN), which provides a hardness of approximately 80 HRC, making them highly resistant to wear. The TiN coating's low coefficient of friction reduces heat generation and energy consumption during drilling, resulting in cleaner and more efficient holes. Technical specifications Tip Diameter: 3.5mm Overall Length: 70mm Working Length: 39mm Material: High-quality high-speed steel (HSS) Coating: Titanium nitride (TiN) Hardness: Approximately 80 HRC Compatibility and accessories Compatible with standard drill chucks Suitable for use with electric drills, cordless drills, and drill presses No additional accessories required for basic use Installation Insert the drill bit into the drill chuck and tighten securely Ensure the drill is set to the appropriate speed for the material being drilled

The Irwin HSS Pro TiN drill bits are primarily designed for drilling metal and harder tougher alloys. Compared to traditional HSS twist drill bits speed can be increased by 40 -60% and feed by 10 -20% without reducing the life time of the drill bit significantly. TiN is also a poor conductor of heat so the heat generated during the drilling process is diverted into the chips and coolant and less into the drill bit. These drills have a 135° split point grinding tip which ensures perfect centring and reduced drilling pressure. The drill bit body is manufactured from high quality HSS steel coated with 2.5µ Titanium Nitride (TiN) the TiN coating has a hardness of app. 80 HRC and is very resistant to wear. TiN has a low coefficient of friction this results in less power being consumed and less heat generated during the drilling.The Irwin IRW10502580 HSS Pro TiN Coated Drill Bit comes in the following:Size: 3.5 x 70mmPTDIRW10502580
