RS PRO Cobalt High Speed Steel, 133mm Overall 5

Thanks to its high-speed cobalt (HSCo) body, the robust drill bit has the heat resistance necessary for using your power tool at top speed. An amber finish provides additional corrosion resistance for use in harsh environments. It conforms to the DIN 338 standard specifying dimensions for twist drills, so it will drill standard hole sizes for components and fasteners.

This drill bit is appropriate for general workshop jobs as well as professional maintenance and engineering. Use it to drill through hardened, stainless and alloy steel, as well as cast iron and titanium.
