forgot to say, the rrp on those is £5 each so if i give you them half price i reckon you owe me about 500 quid
give or take fifty quid or so.
Joking aside, i drilled through some 15mm hard plate on the stumpgrinder at work this morning, i couldnt be arsed with slow and steady cos it was in a hard to reach position. The bit was smoking like mad at full speed but went through no problem, it didnt blunt it a bit.
