Description

The Irwin 5.5mm HSS Cobalt Drill Bit is designed for medium-duty drilling in stainless steel and other high alloys. This diameter is particularly useful for larger clearance holes, pilot holes for tapping operations, and general metalworking applications where a balance between hole size and precision is required. 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, efficient chip removal to prevent binding and maintain optimal performance. The attractive golden tempered surface finish indicates the superior heat treatment process that makes this bit ideal for professional metalworking applications. Features and Benefits: • 5.5mm diameter for medium-duty applications • 5% Cobalt content for superior heat resistance • 135° split point for perfect centring and reduced pressure • Industrial quality ground flute for accuracy and chip removal Specifications: Tip Diameter (mm): 5.5 Working Length (mm): 57 Overall Length (mm): 93 Pack Qty.: 1
