HSS Pro Ti N Coated Drill Bit (2) 1.0mm OL:34mm WL:12mm
- IRWIN 10502600, The Irwin HSS Pro Ti N drill bits are primarily designed for drilling metal & harder, tougher alloys. Compared to traditional HSS twist drill bits, speed can be increased by 40 -60% & 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 & coolant & less into the drill bit. These drills have a 135° split point grinding tip which ensures perfect centring & 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 & is very resistant to wear. Ti N has a low coefficient of friction, this results in less power being consumed & less heat generated during the drilling. Irwin HSS Pro Ti N Coated Drill Bit. Size 11.0 x 142mm.
