Irwin® 10502560 Hss Cobalt Drill Bit 7.5Mm Ol:109Mm Wl:69Mm

The Irwin 7.5mm HSS Cobalt Drill Bit excels at larger hole drilling in stainless steel and other high alloys, providing the performance needed for demanding metalworking applications. This diameter is particularly useful for pilot holes before larger drilling or tapping operations, and for general fabrication work where durability matters. Manufactured from high quality HSS steel with 5% Cobalt content, this drill bit offers exceptional heat resistance and significantly extended life when drilling demanding materials. The added Cobalt improves the red hardness of the bit, enabling it to maintain its cutting edge under the high temperatures generated during drilling operations in stainless steel and high alloy materials. The 135° split point grinding ensures perfect centring from initial contact, reducing drilling pressure and eliminating the need for centre punching in many applications. An industrial quality ground flute design ensures high accuracy drilling whilst facilitating fast,
