Mortise Chisel Bit 1/2"e
|The bit removes most of the material, and the chisel squares up the sides, allowing you to cut precise 1/2" mortises for mortise-and-tenon joints. Fits the Jet Benchtop Mortising Machine (#81421, sold separately). Recommended for use with mortise machines, however, does not work with Delta 14-651.
