Warning: Make sure the router bit is properly fastened and tightened in the router’s collet and the bit can rotate freely without any obstructions.
Instructions: Slowly dial up the RPMs on your router to the recommended maximum. Then, dial back if needed to find the “sweet spot”. The sweet spot is the speed at which the least resonant vibration is present. If the sweet spot cannot be achieved within 5,000 RPMs of the max, check the collet for residue or other debris and start over.

A tongue and groove joint is the ideal way to create flat, even joints for flooring, wainscoting, panels and tabletops. Tongue & groove router bit sets will cut the 2 mating profiles for this easy to make woodworking joint with ease and with a simple setup. This joint also provides a lot of gluing surface as well as aligning ease. Tongue and groove bits can take quite a big bite out of the wood, so using these bits in a router table is strongly recommended. Even though some smaller tongue and groove cutting router bits can be utilized in a hand-held router the stability of a table will help keep the joint perfectly square. For best results, use with solid wood only.
