I am cutting out some model boat parts in .25 (4mm) Finnish birch ply. I have been using the 1/8" cutting bit in one pass with good success however I want to sharpen the inside radius of some of the parts and plan to use the 1/16" cutting bit. Can I do this in 4mm ply in one pass without breaking the bit, or do I limit it to .125 (1/8") pass depth? I have to cut out quite a number of these pieces so cutting time is a factor.
thanks,
