Slow rpm, lots of lube and plently of pressure.
If you let it rub it will work harden.
300 x 15 ÷ hole saw diameter = RPM
300 x 15 ÷ 76 = 59rpm
Slower is ok but faster will blunten the cutter.

There's a few different techniques for cutting the slots, (there's a few threads around just can't find them at the minute). I put my 4" grinder securely and i mean securely in my wise and held my caps and gently pushed them into the blade, it’s not as scary as it sounds just remember the blade will try flick them out so don't stand down wind and WATCH your fingers.

Yep, my RC wasn't very efficient and the addition of copper scrubbers means it can hold full reflux now, not as an additional reflux module but to transfer the cooling more efficiently just as woodduck said.
