This is a Whiteside template/pattern bit, model 3010, ground for pattern routing and duplicating parts from a template. It measures 3/4″ cutting diameter, 1/4″ shank, and uses carbide cutting edges that resist heat and hold an edge far longer than plain steel.
Chuck it into a router table or handheld router to duplicate curved parts, follow a template for repeatable shapes, or clean up bandsaw cuts. The balanced bit runs true at speed, so cuts come out concentric and clean with minimal sanding afterward.
Whiteside Machine Company manufactures its router bits in Claxton, Georgia, and is consistently rated among the top-performing router bit makers in independent woodworking tests.
