Literally, every cabinets are built using rabbet joinery somewhere. For example, lock-rabbet drawers and inset doors. A good Rabbet Router Bit helps you to cut rascally rabbets on curved edges, such as an arch-topped door which is not possible to do with a an ordinary table saw.

The bearings set give Rabbet Router Bits more versatility as the bearings are replaceable to alter the cutting width of the bit. Rabbet cutting depths are as follows: 1/2", 7/16", 3/8", 5/16", 1/4" & 1/8". 6 bearing sizes include: 3/8", 1/2", 5/8", 3/4", 7/8" and 1-1/8" with inner diameters of 3/16". Two flute carbide cutters and 1/4" or 1/2" shank. To determine the width of your rabbet with a specific bearing, subtract the bearing’s diameter from that of the bit; then divide that result by two. Or, to determine which bearing to use for a specific rabbet size, simply multiply the rabbet width by two; then subtract the result from the bit diameter. The large diameter of a rabbeting bit requires a slower router speed—from 16,000 to 18,000 rpm—to perform at its best.

Note: Check the spin of the bearing before using a rabbeting bit. Some bits use stepped washers between the bearing and bit, as shown below , and if installed upside down, will keep the bearing from spinning.
