HSS Cobalt Drill Bit Metal 5.5mm Pack 10

The IRW10502529 is a 5.5mm HSS Cobalt Drill Bit supplied in a pack of 10, providing an intermediate diameter that's ideal for specific applications in stainless steel and high alloy steels. This size is particularly useful for clearance holes, pilot drilling for larger bits, and applications where precise sizing between standard diameters is required. The 5.5mm diameter is commonly used in engineering and fabrication work. With 5% cobalt integrated throughout, this drill bit delivers outstanding heat and abrasion resistance, ensuring consistent cutting performance even in the most challenging materials. The heavy-duty web construction provides excellent rigidity and strength, minimising flexing and breakage risk. The precision-ground 135° split point ensures immediate cutting action with minimal pressure required, reducing bit walk and guaranteeing accurate hole placement.
