Review on Carbide Carving Router Bits with Optimal Cutting Diameter - SpeTool Cutting Tools by Terrance Fisher

This cutter is very well made. It's very hard and very sharp. I like the 1/2" shank that tapers to 3/8" but is long enough that I can cut the groove to full depth without getting in the way of the shank. It is very good for picking up chips from the hole when cutting. Since carbide can be brittle but very strong, I would suggest making a few shallow cuts rather than a pass or two in the groove or hole you want to cut. All in all, it's worth the purchase price.
