Hi Dusty, thanks for your reply, I have three sixes 5mm 10mm and 13mm , I have only used the 5 and 10mm the 13mm is still new . I used them in 12v cordless hand drill black and decker, the speed I dont know but it feels a lot slower than the standard corded mains drill. It sounds from your reply that this may be the probelm

I have lot of mild steel drilling to do and thought I would buy solid carbide drill bits with the idea they would drill more holes before needing sharpening, but they quickly chipped the cutting edges and became ineffective. what am I doing wong ?

thanks
