Irwin HSS Cobalt Drill Bit for Metal

The IRW10502524 is a 4.5mm HSS Cobalt Drill Bit supplied in a pack of 10, offering an intermediate diameter that's perfect for specific metalworking applications in stainless steel and high alloy steels. This size is particularly useful when working with imperial-sized tapping requirements or when precise hole sizing between standard metric diameters is needed. The 4.5mm diameter finds regular use in engineering workshops and fabrication environments.

The 5% cobalt content throughout the drill bit provides superior heat and abrasion resistance, ensuring the cutting edge remains sharp even under demanding conditions. Heavy-duty web construction delivers the strength and rigidity needed for reliable performance, whilst the precision-engineered 135° split point geometry ensures the bit starts drilling immediately without wandering, providing accurate hole placement with minimal effort.
