IRWIN IW3038501 - HSS Titanium drill bit set (multi-pack)

Description

135° SPLIT POINT GRINDING - Ensures perfect centering and reduced drilling pressure. INDUSTRIAL GROUND FLUTE - For high accuracy drilling and fast removal of chips . TITANIUM NITRIDE (TIN) COATED HIGH QUALITY STEEL BODY - Resists heat and friction, providing up to six times longer life than standard metal drill bits. 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. SPEED AND FEED - 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. LESS HEAT - 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.
