Hey all, I haven’t asked a question on here in some time, but I have something that I just can’t seem to find the answer to.
I’d like to try a bearing guided spiral bit, in hopes that the spiral action will help reduce or eliminate tearout. Will that help? And if so, which bit do I choose, an upcut spiral or a downcut spiral? I’ve read about the differences and I think I have a grasp on that, but I can’t seem to figure which one will be better for template routing? I’m thinking I want an upcut to move the chips down towards the router and away from the bearings otherwise the chips may interfere with the bearing riding smoothly along the template. Is that correct?
Thanks for your help.
Here is what I'm considering...
