Irwin HSS Cobalt Drill Bit

The Irwin 1mm HSS Cobalt Drill Bit is perfect for precision drilling applications in stainless steel and other demanding materials. This fine diameter makes it ideal for pilot holes, delicate fabrication work, and applications requiring exact hole placement. Supplied in a convenient pack of 2, you'll have a spare ready when needed. Manufactured from high quality HSS steel with 5% Cobalt content, this drill bit offers exceptional heat resistance and durability when working with challenging materials. The 135° split point grinding ensures the bit centres perfectly on your mark, even on curved or angled surfaces, whilst reducing the drilling pressure required. The industrial quality ground flute design removes chips efficiently, preventing binding and maintaining cutting performance. The golden tempered surface finish indicates the superior heat treatment process that gives this bit its enhanced performance characteristics, making it significantly more durable than standard HSS bits when drilling stainless steel and high alloys.
