One factor to consider when purchasing router bits is shank size. Also, utilize a safety guard and avoid working with small pieces of stock. In addition, use push blocks when needed to keep your hands a safe distance from the bit. No matter set which you go with, as we mentioned in our previous update, follow safe woodworking practices by wearing eye and ear protection. Note that it’s not intended for use with handheld routers. This one features a 1/2-inch shank and is made up of tempered steel.
#ADJUSTABLE TONGUE AND GROOVE ROUTER BITS FULL#
For another model from a well-known name in the industry, check out the Bosch 84623M which, like the Porter-Cable selection, consists of just one shank after you use the full assembly to create the tongue component of your joint, simply remove one of the cutters to forge the grooved piece. The Freud set is covered in a patented coating to reduce pitch buildup, while the components of the Whiteside model are made of tough premium carbide, and their precision-ground build ensures they’ll stay balanced at high RPMs.

We kept the Freud Adjustable Set and the Whiteside 5990 in their top slots, as both of these are from established brands in woodworking tools and can be counted on for clean and precise results. We considered adding in a 1/4-inch-shank Tacklife RB31C, but decided to leave it out due to mixed reviews, including some users who felt it cut through stock too roughly. It’s made by a century-old tool manufacturer that’s now a subsidiary of Black & Decker.

Included are three-wing slot cutters, a 1/2-inch arbor bearing, and the shims and spacers to allow you to adjust it, as needed. This tool proves useful for projects like T-molding installations and weather stripping. It comes with the components you need for creating not only tongue-and-groove joints but also rabbets and dadoes, so it can serve as a slot cutter router bit as well. In today’s update, we added in the Porter-Cable 43392PC, a versatile 1/2-inch shank set.
