Whiteside Template Bit, 1/2 in. SH x 3/4 in. CD x 2 in. CL is a high-quality template router bit designed for precision and durability. This standard straight 2-flute template guide router bit is for making exact copies and multiple reproductions. Its top bearing, located on the bit shaft, allows you to place template patterns directly on top of your workpiece, providing greater visibility and accuracy. I for sign making and template-guided tenon fixtures, this bit features a carbide tip for long-lasting sharpness and performance. It comes equipped with a B19 bearing (1/2" ID x 3/4" OD), though Whiteside recommends using their more robust 1-1/8" diameter bits when possible due to the delicate nature of the B19 bearing. The specifications include a 1/2" shank size, 3/4" cutting diameter, 2" cutting length, and an overall length of 3-5/8". Model Number: 3023
