Router Bit RPM Chart
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.

From time to time, router bit bearings need to be replaced due to normal wear and tear. Because you never know when a bearing will suddenly seize or break, it's always a good idea to have a few extra bearings around. Bearings with an inner diameter of 1/4" or 1/2" are often used as shank bearings for template or flush trim router bits with shank diameters of those sizes. Bearings with a 5/16" inner diameter are used as part of a router bit assembly, common in tongue & groove and rail & stile bits, which are placed on a router bit arbor that has a 5/16" diameter. Bearings with a 3/16" inner diameter are used on the end of flush trim, edge forming or rabbet router bits with an end stub that has a 3/16" diameter. Our fully-enclosed bearings are smooth and well balanced and are made to withstand heavy use.
