What size hole should I draw for 18mm plywood?

Jerry: Are there any more details about this file?

GC3: Good to know! I presume if you draw 18.25mm you get 18.25mm though...

Change your machine to inches and run it I didn't realize where you are from. Once you get it to cut the correct dimensions you can change it back.

Allowances always have to be made when cutting male and female parts. A lot depends on bit deflection, climb/conventional cutting, material, speed of cut etc etc.

James, I seem to remember your .25" bit was in database as EXACTLY .25", are you absolutely SURE the tip measures that? Sorry to sound like a broken record, but not a single one of my 1/4" bits measure .250". Also check material several different places like Gene says. TJ normally has 3-4 different versions of his ply files and the only thing different is ply thickness. Glad things are better, but the only thing you should be having to change is your pocket allowance depending on the type of fit you want.
