Top and bottom bearing router bit is ideal for large stock trim applications. This bit can be used with either a top or bottom template. It is especially useful for template work when routing rounded or curvy wood with sensitive end-grains. The top and bottom bearings allow you to flip over the wood stock when you reach "up-grain" and route that segment in a "down-grain" direction, maintaining uniform smoothness around the workpiece. This highly durable bit is suitable for demanding industrial applications.
