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 -2 more→0% 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 …

The DT4932 Dewalt cobalt drill bit is 8% cobalt which maintains a sharper cutting edge and delivers 4x longer life versus DEWALT Black Oxide bits. The optimised tip and flute geometry delivers 2X the more→penetration speed, versus DEWALT Black Oxide bits, removes material faster and reduces heat build up. The stronger central core delivers 2X the resistance to breakage versus DEWALT Black Oxide drill bits. Specifications • Diameter: 5.5mm • Length: 93mm • Working length: 57mm • Pack Quantity: 10
