This 7.0mm HSS-CO cobalt drill bit from Bosch is designed for reliable drilling in tough materials. Fully ground from high-speed steel with added cobalt, it offers enhanced wear resistance and manages heat build-up during use.
Typically used on site for drilling stainless steel, alloyed and non-alloyed steels, cast iron, and heat-resistant metals, this bit is suitable for use with drill stands or drill drivers. Its cylindrical shank fits three-jaw chucks, supporting accurate and steady drilling tasks for trades and maintenance work.
