Irwin HSS Cobalt Drill Bit for Metal – 10502534

The IRW10502534 is an 8mm HSS Cobalt Drill Bit supplied in a pack of 5, representing a larger diameter ideal for heavy-duty applications in stainless steel and high alloy steels. This size is perfect for structural fixings, larger brackets, and mechanical assembly where substantial hole diameter is required. The 8mm diameter is commonly specified in construction, fabrication, and engineering projects involving robust metalwork. Engineered with 5% cobalt content, this drill bit provides superior heat and abrasion resistance, crucial when drilling larger diameter holes that generate more friction and heat. The heavy-duty web construction delivers maximum strength and rigidity at this larger diameter, ensuring reliable performance without breakage. The precision-ground 135° split point ensures immediate cutting action, effectively eliminating bit walk and providing accurate hole placement even when drilling through challenging materials.
