Spiral bits provide a shear cutting edge that leaves a smoother cut than standard router bits. The down cut spiral design provides the best top surface edges, ejecting chips away from the router when routing through material. This design also decreases the tendency to lift thin/small work pieces during CNC routing.

Materials: Natural woods, composites, hard plastics, thin aluminum

Whiteside Machine Company was founded in 1970 by Bill and Bobbie Whiteside in their home basement in Western North Carolina. Initially a general-purpose machine shop, the business focused on repairing and creating parts for the local woodworking and furniture industry. With a commitment to quality, problem-solving, and innovation, the company grew into a full-fledged manufacturer of woodworking equipment and router bits. Today, Whiteside operates out of a 40,000 sq. ft. facility, producing a comprehensive range of solid carbide and carbide-tipped router bits. Family-owned and dedicated to quality, Whiteside continues to innovate through advanced production techniques and customer feedback.

Whiteside Router Bits have twice earned top ratings in Fine Woodworking Magazine. In issues #137 and #191, Whiteside bits were awarded Best Overall and Best Value for their exceptional quality and performance in independent tool reviews.
