Cobalt Drill Bits

These heavy-duty drill bits are coated in cobalt for increased heat resistance and durability when drilling metal and steel. They can also be used on alloy, hardened steel, cast iron, titanium and stainless steel. Choose cobalt drill bits when you need to bore holes into hard surfaces.

HSS Drill Bits vs HSS Cobalt Bits



HSS stands for high-speed steel. These durable drill bits are designed to withstand the additional heat from high-speed drilling. Cobalt coated HSS drills offer even more protection. Titanium coated HSS bits are also available, but cobalt is more durable long-term making HSS cobalt drill bits a premium choice.

Cobalt drill bits come in various sizes and can be purchased as single bits or as part of a set. At Toolstation, you’ll find a quality selection of bits and sets from brands such as DeWalt, Heller and Toolpak.
