IRWIN HSS Cobalt Drill Bit 13.0mm (151mm)

The IRWIN HSS Cobalt Drill Bit is engineered for precision drilling in hard materials, particularly stainless steel and other high alloys. Its 135° split point grinding ensures perfect centring while reducing drilling pressure, making it ideal for efficient and accurate drilling in demanding applications.

Crafted from high-quality HSS steel with 5% cobalt (Co), these drill bits offer superior red hardness (heat resistance), significantly extending tool life. This makes them perfect for industrial use where high performance and durability are essential. The attractive golden tempered surface finish not only looks professional but also provides additional protection against wear.

The industrial-grade ground flute ensures high drilling accuracy and fast chip removal, preventing clogging and enhancing performance. Whether you're working on stainless steel, high-grade alloys, or other tough materials, the IRWIN HSS Cobalt Drill Bit delivers consistent, reliable results.
