When template work is in the picture, nothing beats the simplicity and utility of a router template guide bushing. With no moving parts to break, router bushings pump out part after identical part, and are never worse for wear. These guide bushings are available in a wide range of diameters for different bits, dovetail jigs and other template routing applications. They fit perfectly in any router base with a 1-1/4" diameter center hole. Locking nuts (#63107, sold separately).
