The irwin 6.5Mm hss cobalt drill bit offers excellent performance for medium to larger hole drilling in stainless steel and other high alloys. This diameter is particularly useful for pilot holes before tapping, clearance holes for larger fixings, and general metalworking applications requiring reliable performance 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.
