Rabbet planes used to be widely available, but are now being discontinued by manufacturers. Veritas® developed this specialized plane to convert a chisel into a rabbet plane.
The body is made of ductile cast iron and is configured to hold a 1" (25mm) bevel-edge chisel at a 45° angle, the same pitch as used on bench planes. It becomes a small plane that works equally well as a shoulder plane or rabbet plane and can be used to clean up machine-cut rabbets and tenons. It works like a butt mortise plane for cutting hinge gains. It will also cut 1" (25mm) dadoes and grooves up to a depth of 3/8" (9.5mm).
Precisely machined. Overall size is 1-3/8" (35mm) wide by 5-1/2" (140mm) long by 2-1/2" (63mm) high. The clamping screw is made of solid brass.
While it excels as a job-site plane, it is equally handy in the shop.
