Customer Reviews for Bosch HSS-R Drill Bit 6 x 93mm
"Just needed one 6mm drill bit as I forgot to pack my set in the tool box. Thought I give this Bosch one a go and see how it compares to the multi pack of disposable ones from the far east. Well I was very surprised on the way it drilled through the cast iron. Not the softest of metals to undertake a test on, but if it holds up on other materials and lasts longer than the cheeper ones i'll be buying Bosch from now on!"
