Description: The Irwin HSS Pro Ti N 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. Ti N 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 (Ti N), the Ti N coating has a hardness of app. 80 HRC and is very resistant to wear. Ti N has a low coefficient of friction, this results in less power being consumed and less heat generated during the drilling. Irwin HSS Pro Ti N Coated Drill Bit. Size 7.5 x 109mm. Additional Information: ● Tip Diameter: 7.5mm ● Working Length: 69mm ● Overall Length: 109mm ● Pack Qty.: 1.
