I had a good drill bit, but too much speed. Have got a couple of good 135 deg cobalt bits from Sulco now.
Appreciate the help guys.

Quick update on drilling. New bits arrived, halved drill speed, used new paste and it cuts like butter.
What a relief, I was starting to hate stainless.

Lol.
Sweet Pauly. Be a shame to have to use a less durable metal. Looking forward to progress resaults on pistols now you've beaten this problem. |

Yeah I thought a nice sharp drill was all i needed to drill S/S.
Blunted drills, hardened stainless and a fitter mate taught me the error of my ways. |
