Cut cleaner, more precisely fitting dovetails with this 17/32" dovetail bit from Rockler. It's an ideal replacement dovetail bit for the Porter-Cable 4210 and 4212 dovetail jigs. With two finely ground carbide cutters, it stays sharper, longer, and its 1/2" shank increases rigidity for a more stable cut.
