Solid carbide spiral bits are a great choice for anyone who is serious about performance and value. Spiral Bits are unsurpassed for cleaner cuts in ordinary or difficult materials, softwood, hardwood, plywood, composites etc. The spiral cutting edge stays in continuous contact with the workpiece, providing a smooth, chatter-free cutting action. Ground from the finest micrograin carbide stock, CMT's Spiral Bits feature the latest in bit geometry, with low helix angles for fast chip ejection. The Upcut bit is the best choice for a fine finish on the lower surface, or choose the Upcut & Downcut bit (series 190) for the finest finish on both sides of the workpiece. Spiral bits are ideal for use with C.N.C. or handheld routers.
