Pro-Tech | Router Bit, Rabbeting, 1-1/4" X 3/8" X 3/8" Depth, 1/4" Shank

Rabbeting Cutter

For cutting rebates

Rabbet: (răb′ĭt) also re·bate (rē′bāt′,răb′ĭt)
A cut or groove along or near the edge of a piece of wood that allows another piece to fit into it to form a joint.

By choosing alternative bearings with a larger outside diameter, the depth of cut can be reduced. The cutting height can be increased with multiple passes.

Popular with picture framers and joinery where a lap joint is required.
