Whiteside UDC9213 Ultra-Long Trim Combination Router Bit is designed with a 2 + 2 compression design that delivers top performance and quality, similar to Whiteside's Classic Bits, but specifically made for thicker stock. This router bit produces a crisp, clean edge on both the top and bottom edges of your workpiece, even when working with challenging wood grains. Equipped with both a top and bottom bearing, it allows you to work with either a top or bottom template for versatile use. For optimal results, it is to use the shortest cut length necessary for your application. Made from solid carbide, this bit can handle materials up to 2-1/8" thick. Manufactured by Whiteside Machine Company in Claremont, North Carolina, it combines durability and precision for professional woodworking projects. Model Number: UDC9213
