CMT Rabbeting Router Bit - 12.7mm x 12.7mm - 1/4" Shank

The CMT rebating bits are the easiest and fastest way to create a rebate for a recess or butt joint. The bearing gives a guide that the bit follows on either straight or curved materials, making them great for milling tongue and groove joints, and even re-grooving old timber windows to fit thicker insulated glass.
