Irwin HSS Cobalt Drill Bit 4.5mm Pack of 1
The Irwin 4.5mm HSS Cobalt Drill Bit is designed for precision drilling in stainless steel and other high alloys, offering a versatile diameter for various metalworking applications. This size is particularly useful for clearance holes, pilot holes for larger operations, and general fabrication work where durability matters. 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.
