Hi all,appologies if this has been covered but cant find it,what are the best type of drill bits to use on stainless for pilot holes for Qmax hole punch.

As john said and as advised keep them cutting not skating and heating up ;)
Have a look here
Using a short drill allow a better pressure to be applied. :)

Yes. I'd start off with a 4mm pilot hole, then it was a 10mm for the 21mm q-max and an 8mm for the 12.7mm q-max. Once the pilot holes are drilled, the larger drills go through so flippin' quick so be careful you dont slam the chuck into the side of the pot!
