Cutting deeper than flute length
What's the word on cutting deeper than your flute length? For a project I'm working on, I need to precisely profile some wood stock (hard maple) that is 2.80" tall and my 1/2" bit has a flute length of only 1.5". I've found extra long that has a 3" flue but the darn tool is 6" LOA. All I really need is 3" flutes on like a 4 or 5" shank.
My bit supplier specs the bits at +.000 to -.002 in cutting diameter and I'm just wondering if I can do the full 2.8" depth with the 1.5" bit or whether that's going to cause problems. I can flip the stock but that leads to new inaccuracies.
Any experiences with this?
