Irwin HSS Pro Tin Coated Drill Bit 7.5mm OL:109mm WL:69mm

General description The Irwin HSS Pro TiN drill bits are specifically designed for drilling metal and tougher alloys. They offer increased speed and feed rates compared to traditional HSS twist drill bits, enhancing efficiency without significantly reducing the drill bit's lifespan. The drill bit features a 135° split point grinding tip for perfect centering and reduced drilling pressure, making it ideal for various DIY and home improvement projects. Technical specifications Coating: Titanium nitride (TiN) Size: 7.5 mm x 109 mm Working length: 69 mm Material: High-quality steel alloy Hardness: Approximately 80 HRC Low coefficient of friction Compatibility and accessories Compatible with standard drill chucks Suitable for drilling in metal, wood, and plastic Installation Insert the drill bit into the drill chuck and tighten securely Ensure the drill is set to the appropriate speed for the material Usage Use for drilling holes in metal, wood, and plastic surfaces Apply steady pressure

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.Irwin HSS Pro TiN Coated Drill Bit. Size 7.5 x 109mm.PTDIRW10502594
