The Whiteside 3021 Template Router Bit is super for making exact copies and multiple reproductions because the Top Bearing (bearing on the bit shaft) allows you to place template patterns on top of the work piece for greater visibility. Also useful for sign making and template guided tenon fixtures. Carbide tipped. Double flute. Whiteside Machine Company - Claremont, North Carolina.
NOTE: Due to the fragile nature of the B19 bearing used on their 3/4" diameter 1/2" Template bits, Whiteside recommends the use of their more robust 1-1/8" diameter bits instead whenever possible.
