Whiteside Machine Company has been making top quality router bits since 1970. Using the latest technology, up-to-date machinery, and expert craftsmen, they make a bit that features thick, high grade carbide, accurately ground to produce the smoothest finish cuts on your work. Each bit is inspected after every manufacturing step to ensure satisfaction and consistent quality. This bit is excellent for producing smooth, uniformly rounded edges. Lowering the depth setting will produce a rounded corner with a decorative fillet.
