RS PRO Cobalt High Speed Steel, 109 mm Overall 10

The drill bit is made from high-speed steel (HSS) with 5% cobalt blended into the base material, which makes it strong, durable and heat resistant. The use of high-speed cobalt (HSCo) also means this type of drill is designed for hard materials so you can use it to drill into hardened, stainless and alloy steel, as well as cast iron and titanium. It has an amber finish for additional protection against corrosion.

This piece is suitable for general workshop jobs as well as professional maintenance and engineering when you need to drill into hard materials. It complies with the DIN 338 standard specifying dimensions for twist drills, so you'll be sure you can create standard-sized holes for your fasteners and components.
