About this product
This is a 9.0mm HSS Pro TiN Coated Drill Bit from Irwin, measuring 125mm overall with an 81mm working length, supplied singly. It is designed for drilling metal and tougher alloys, suiting heavy-duty metalworking such as thicker steel sections and structural work, including M12 bolt clearance holes.
The bit is made from high-quality HSS steel coated with 2.5 micron 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 rate by 10-20% without significantly reducing tool life.
A 135° split point grinding tip gives accurate centring and reduces drilling pressure, helping to prevent the bit walking. The TiN coating is a poor heat conductor and has a low coefficient of friction, so heat is directed into the chips and coolant rather than the bit, reducing power consumption during use.
