In 1970, the Whiteside Machine Company began manufacturing special parts and making repairs for the furniture industry in Hickory, NC. As the company's reputation grew, they expended their operations to include product offerings for businesses and hobbists, including high-quality router bits. Today, Whiteside router bits are the undisputed favorite among woodworkers. The spiral flush trim up cut bit creates superior results in flush trimming and can operate in very tight corners. It utilizes a solid pilot against your workpiece template while the up cut flutes move chips up and away from the router resulting in a smooth bottom surface. Model RFT2100: 1/4" shank, 1/4" cutting depth, 1" cutting length, 3" overall length, 2 flutes.
