Hardwoods like mahogany and oak can dull a router bit pretty quickly. Guhdo’s new GMaxx bits are made with a larger-than-normal piece of carbide to allow for more sharpenings over the life of the bit. The profiles are ground to a very precise edge, and each is electronically verified before leaving the factory. Available in 1/4- and 1/2-inch shanks in a variety of profiles. Price: Starting at $10. 855-624-4297. guhdo.com.
