Ultra-Shear router bits are solid spiral tools designed for template work or trimming materials flush with mating surfaces. They use a unique guide element with two bearings, requiring minimal sanding after use. They are excellent for flush trimming and handling tight corners. Featuring a 1/2” shank and a 1/2” cutting diameter, they have two ultra-sharp spiral flutes that cut quickly and efficiently. Available in four different sizes with both up-cut and down-cut options, they ensure a perfect fit for various needs. Made from high-quality solid carbide using advanced CNC grinding equipment, these bits direct chips downward and away from the router, keeping the top surface smooth, making them the best choice for plywood and composite materials like MDF.
