The Fly Cutter Page: Best Surface Finish Tool in the Kit

Most authorities agree that if you need the very best possible surface finish there is, a fly cutter is the easiest way to get there.  Consequently, we get a lot of traffic searching for information on fly cutters, and we already had a page on fly cutter feeds and speeds.  But there have been a ton of other articles scattered all over CNCCookbook plus new material I’ve been keeping back.  Tonight, I uploaded our new Fly Cutter page which brings together all that Fly Cutter goodness onto one page.  We’ll even connect you with sources like Ingersoll who tell you the best finish will be had by removing all but one insert from their finishing endmill, effectively turning it into a fly cutter.  And we’ll reveal the secret behind fly cutting aluminum, specifically, the best insert type to use there for a fine surface finish.  There’s lots of tips and pictures of fly cutter geometry for those willing to do a little freehand tool grinding.

Check it out, there’s a ton of useful information on fly cutters–probably more than you ever wanted to know.
