HSS Pro TiN Coated Drill Bit (2) 1.0mm OL:34mm WL:12mm

<p>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.</p> <p>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.</p> <p>These drills have a 135&deg; split point grinding tip which ensures perfect centring and reduced drilling pressure.</p> <p>The drill bit body is manufactured from high quality HSS steel coated with 2.5&micro; 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.</p><p>The Irwin IRW10502572 HSS Pro TiN Coated Drill Bit come in the following:<br />Size 1.0 x 34mm.</p>
