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.
Featuring a 1/2" Depth of cut and 6 bearings to give a variety of different rebate sizes - 3.2mm, 6.35mm, 8mm, 9.5mm, 11.1mm, 12.7mm.
