A couple of weeks ago I was trying to drill the handle of a stainless steel saucepan so I could replace the faulty rivet, I only had HSS drill bits, so starting with a 3 mm bit I started to drill, Yup you guessed it the bit caught, snapped and went right through my thumb breaking off in my thumb, a quick trip to A@E and all is well again,
I've since bough a set of TCT drills !!
First photo drill in!!
Second drill out!!
