Hi all, I'm in need of some advice.

I have a Mcmillan HTG that requires pillar bedding (current holes are 9/16") and I want to use the ScoreHigh Rem700 pillar bedding kit (which are 5/8" pillars).

What's the best way to drill out the fibreglass stock to 5/8"? With minimum splintering/chipping out... I've been thinking of use a spade bit but looking for some more expert opinions.

Cheers, Jester

A quality forstner bit would be best, but if you mark center well with a very small bit or a little punch a spade could work, but be careful the point doesn't go through

If you have a drill press and a drill press vise, You can get it done with a forstner bit

If you plan on using a hand drill, I'd rather use a dremel tool.
Secure the pillars to the action, take your time, check fit often
