Woodworm hole size?

[Bob Winkler]

I can't seem to find what size hole to pre-drill for my Nova Chuck woodworm screw. Can someone help me out?

Thanks,
Bob

Bob,
I use a 3/8" bit and it works perfectly...

Bob, it needs to be large enough for a starship to fly through. Opps, sorry, I thought you said wormhole. :rolleyes: :D

I use an 11/32" brad point bit and go about 1" deep. :)
