I would run them Screwfix blacksmith drill bits very slowly and lot's of lubricant, they are not the toughest bits, oh and get used to sharpen them on a grinder, or if you are only wanting one size in particular, try buying one quality bit from say Cromwells etc.

Thanks for the reply guys, are these kind of drill bits available where the bottom of the drill bits are flat? I need to cut a flat disk shaped hole that's all and the bottom of the hole must be flat and not domed, if that makes sense lol.cheers again
