IRWIN®

The Irwin 3.5mm HSS Cobalt Drill Bit is a popular size for general metalworking applications in stainless steel and other high alloys. This diameter is commonly used for clearance holes for M3.5 fixings, pilot holes for larger operations, and everyday fabrication tasks in demanding materials. The drill bit body is manufactured from premium HSS steel containing 5% Cobalt, which significantly enhances the red hardness (heat resistance) of the bit and delivers extended service life. This Cobalt content allows the bit to maintain its cutting edge even under the high temperatures generated during drilling operations in stainless steel and other challenging materials. Featuring 135° split point grinding, this bit ensures perfect centring on your mark from the first contact, reducing the drilling pressure required and eliminating bit walk. The industrial quality ground flute design facilitates high accuracy drilling and fast chip removal, preventing clogging and maintaining cutting performance throughout use. The attractive golden tempered surface finish reflects the superior heat treatment process that gives this bit its enhanced performance characteristics. Features and Benefits: • 3.5mm diameter for common metalworking applications • 5% Cobalt for exceptional heat resistance • Perfect centring with 135° split point grinding • Extended life when drilling stainless steel and high alloys Specifications: Tip Diameter (mm): 3.5 Working Length (mm): 39 Overall Length (mm): 70 Pack Qty.: 1
