The best shank diameter for mortise and tenon router bits depends on your router's collet size and the stability you require during cutting. Larger shank diameters, such as 1/2" or 3/4", offer greater rigidity, reduce vibration, and deliver smoother cuts, especially in demanding applications. Smaller shank diameters, like 5/8", can be beneficial for compatibility with smaller routers. Products like the Amana Tool 54131 (1/2" shank) and Timberline 609-130 (3/4" shank) demonstrate this variety, ensuring you can choose a bit that fits your equipment and project demands. A wide range of shank sizes is available, so you can find the perfect match for your setup.
