About this product
These Irwin HSS Cobalt Drill Bits are supplied in a pack of 10, each with a 4.5mm diameter, 80mm overall length and 47mm working length. They are designed for drilling stainless steel and other high alloy steels, making them suited to engineering and fabrication work, including tapping-related and precision hole sizing tasks. Each bit contains 5% cobalt, giving greater resistance to heat and abrasion so the cutting edge stays sharp under demanding use. Heavy-duty web construction adds strength and rigidity, while the 135° split point geometry allows drilling to begin immediately, reducing bit walk and improving accuracy. The bits are manufactured to DIN 338 standards.
