BEST ROUTER FOR WOODWORKING â OVERALL. The DEWALT DWP611PK 1.25 HP Variable Speed Router gets our vote for the top pick of woodworkers. Equipped with a number of clever features, including LED lighting for better visibility, there is little that it canât do.
While you canât assess some factors by eye â such as the hardness and quality of the carbide or the bitâs overall balance, there are things you can look for. High-quality router bits have carbide cutters that have been sharpened to a fine edge and that are thick enough to allow for multiple regrindings. The brazing that joins the carbide tip to the bit will appear even. And high-quality bits will incorporate a design that minimizes the risk of workpiece kickback.
