Irwin 10502593 HSS Pro TiN Coated Drill Bit 7.0mm Pack of 1

The Irwin IRW10502593 is a 7mm diameter HSS Pro TiN Coated Drill Bit measuring 7.0 x 109mm in size, supplied individually. This diameter is widely used for M10 bolt clearance holes and medium to heavy-duty metalworking applications, offering excellent versatility for drilling steel, aluminium, and tougher alloys in industrial and workshop environments. The 7mm size combined with the 109mm overall length provides excellent depth capacity for thicker materials and stacked metal sections. The Titanium Nitride coating delivers impressive performance improvements, with drilling speeds 40-60% faster than traditional HSS bits and feed rates boosted by 10-20%. The 135° split point grinding tip ensures perfect centring without walking, reducing the need for pilot holes in most applications. Manufactured from high-quality HSS steel with a 2.5µ TiN coating (80 HRC hardness), this drill bit provides exceptional wear resistance even in demanding conditions.
