The G0645 1/2 HP Benchtop Mortising Machine

Designed for cutting square holes in lumber, commonly used for mortise and tenon joints. Recognized as Top Value by Wood Magazine, it features a rack-and-pinion fence, a six-position handle, and a riser block providing an additional 1-1/4" stroke to the column.

Constructed with rigid cast iron and equipped with rack-and-pinion head control on a dovetail column, this mortising machine ensures precision in producing mortises. It includes a pneumatic return strut for easing the step-and-repeat cycle during multiple mortise creation, and a riser block that extends the maximum stock thickness to 6".

Powered by a 1/2 HP motor, the machine accommodates various wood types. The easy-access drill chuck simplifies chisel changes, and the package includes four mortising chisels. Additional mortising chisels for different sizing needs are available.

Consider upgrading to the G0840 Mortise Machine for a dedicated workstation capable of cutting compound angles. Like all Grizzly mortising machines, the G0645 comes with a 1-year warranty covering parts, excluding consumables.

Your machine comes with a comprehensive, easy to follow manual written by the Grizzly HQ documentation department right here in the USA.
