Review on Flytuo Roundover Rounding Edge Forming Woodworking by Kevin Carey

As you can see from my photos, the radius of curvature of these bits is tiny (when rounding 64 inches you get about 1/32", 1/16" and 1/8" radius') and are therefore best suited for dense hardwoods where you can really see small curves, as softwoods vary too much, even with a clean edge, to go from 1/32" or 1/ 16" to benefit radius Use on hardwood is also the reason these bits have four cutting edges.
