The Irwin 12mm HSS Cobalt Drill Bit excels at heavy-duty drilling in stainless steel and other high alloys, offering excellent performance for substantial metalworking applications. This popular larger diameter is commonly used for M12 clearance holes, pilot holes for larger drilling or tapping operations, and general heavy-duty fabrication work in demanding materials. 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 drilling operation. The attractive golden tempered surface finish indicates the superior heat treatment process that gives this bit its enhanced capabilities for professional use. Features and Benefits: • 12mm diameter for M12 clearance holes and heavy-duty work • 5% Cobalt content for superior heat resistance • 135° split point for perfect centring without centre punching • Industrial quality ground flute for accuracy and chip removal Specifications: Tip Diameter (mm): 12.0 Working Length (mm): 101 Overall Length (mm): 151 Pack Qty.: 1
