1/2" Dia x 3/4" Carbide Tipped Mortising with Upper Ball Bearing, 2 Flutes, 1/4" Shank

There is no faster method for producing multiple mortises than with a template. And the accuracy achieved with a template is unparallel. These mortise bits are specially designed for use with templates, both linear and curved. If you′ve ever used a bushing with template work then you′ll appreciate these bearing-guided bits; there′s no need to calculate offset – ever. Instead, the mortise is sized exactly to the template. And, unlike a bushing on the router sub-base, the guide bearing is always concentric to the cutting circle of the bit. This ensures precise cuts each and every time.
