Whiteside 3021 Template Router Bit with Ball Bearing Guide (Shank: 1/2", Cutting Diameter: 3/4", Cutting Length: 1-1/4", Overall Length: 3")
Standard Straight 2 flute Template Guide bits.  Super for making exact copies and multiple reproductions because they allow you to place template patterns on top of the work piece for greater visibility. Also useful for sign making and template guided tenon fixtures. Whiteside recommends the use of the 1-1/8" diameter bits with 1/2" shank whenever possible due to the fragile nature of the RB19 bearing used on the other diameter bits listed below. 2 flute. Carbide tipped. Made by Whiteside. USA
