After some decent drill bits

[acealfa]

I'm in the process of drilling some bolts out but going through drill bits like butter.

Can anyone recommend a place for good quality ones?

The last ones I brought were expensive but still really bad.

Cheers

Thanks for the advice. I think that may be where I'm going wrong.

I'm looking to drill a 10mm hole, is it best to start small with a 3mm and build up, say to a 6mm then 8mm and 10mm or just go straight in with a 10mm?

Thanks all for the advice. I purchased some WD40 lithium grease and had great success slow drilling. My instinct has always been to drill fast but now I know better.
