    Ball Nose Upcut vs. Downcut

    I was about to start doing some 3D cutting and needed some bits. I am seeing that I have options for Up and down cut. As long as I am doing a roughing cut first, does it really matter?

    Re: Ball Nose Upcut vs. Downcut

    Up-cut is standard, because it evacuates the chips. Down-cut is used when you're cutting plywood or laminates and want to avoid pulling up chips in the top veneer. If you're running a roughing pass first, that's not going to be an issue, so go with the up-cut bits.
