Did the Job - Power & Hand Tools

I have drilled a lot of broken screws in my job and one screw did not come through the screw which most likely has somehow hardened from trying to drill it out. He blunted 3 HSS bits and then moved on to it and he got the job done, hopefully he can handle a few more but saved a lot of time.

Pros

STRENGTH: The Bosch CO14 drill bit set is made of cobalt and is designed for drilling in hard and abrasive materials such as stainless steel, cast iron and high density metal. Also suitable for general drilling in thin metal, wood and plastic.

Cons
