Irwin HSS Cobalt Drill Bit for Metal

The IRW10502541 is a 13mm HSS Cobalt Drill Bit supplied in a pack of 5, representing the largest diameter in this range for heavy-duty applications in stainless steel and high alloy steels. This substantial size is ideal for large structural fixings, heavy-duty brackets, and mechanical assembly where maximum hole diameter is required. The 13mm diameter is commonly specified in construction, structural fabrication, and heavy engineering projects.

With 5% cobalt content engineered throughout, this drill bit delivers outstanding heat and abrasion resistance, absolutely essential when drilling larger diameter holes that generate substantial friction and heat. The heavy-duty web construction provides exceptional strength and rigidity at this substantial diameter, ensuring reliable performance without breakage even under the most demanding conditions. The precision-ground 135° split point ensures immediate cutting action, effectively eliminating bit walk and guaranteeing accurate hole placement in tough materials.
