About this product
This Irwin HSS Pro TiN Coated Drill Bit measures 5.0mm in diameter, with an overall length of 86mm and a working length of 52mm, supplied singly. It is designed for drilling metal and tougher alloys, making it suitable for medium-duty metalworking and fabrication tasks such as M6 bolt clearance holes. The bit is made from HSS steel coated with 2.5µ Titanium Nitride, giving a hardness of around 80 HRC and good wear resistance. Compared with standard HSS bits, speed can be increased by 40-60% and feed by 10-20% without significantly reducing tool life. TiN's low heat conductivity and friction mean less heat and power are used during drilling, as more heat is diverted into chips and coolant. A 135° split point tip provides accurate centring, reducing drilling pressure and preventing the bit from wandering when starting a hole.
