IRWIN®

The Irwin 3.3mm HSS Cobalt Drill Bit offers precision sizing for specialist metalworking applications in stainless steel and other high alloys. This specific diameter is particularly useful for exact clearance requirements and technical fabrication work where standard sizes won't suffice. The 3.3mm size fills an important gap in your drill bit selection. Manufactured from high quality HSS steel with 5% Cobalt content, this drill bit delivers exceptional heat resistance and significantly extended life compared to standard HSS bits. The added Cobalt improves the red hardness of the bit, enabling it to maintain its cutting edge under the high temperatures generated when drilling tough stainless steel and high alloy materials. The 135° split point grinding ensures the bit centres perfectly from initial contact, reducing drilling pressure and eliminating bit walk for accurate hole placement. An industrial quality ground flute design ensures high accuracy drilling whilst removing chips efficiently, preventing binding and maintaining optimal performance throughout the operation. The attractive golden tempered surface finish indicates superior heat treatment.
