Rigid cast-iron construction and rack-and-pinion head control on a dovetail column help ensure this Benchtop Mortising Machine will produce precision mortises every time. A pneumatic return strut eases the step-and-repeat cycle when making multiple mortises. A riser block is also included to increase the maximum stock thickness to 6". The 1/2 HP motor powers through any type of wood and the easy-access drill chuck makes it simple to change chisels. Includes 4 mortising chisels!

Great value 12/20/2017

I own a small woodworking business and have bought several machines from Grizzly. This bench top mortising machine is like all the rest. Excellent quality, craftsmanship and value. I would highly recommend this machine.

top notch 11/3/2017

I received it last month and is a great addition to my shop

Good product, but the shipped assembly could be better 7/5/2017

Product works well, but it shipped with the chuck unattached to the shaft. Also, cannot move the rail when extension block is installed. As moving the rail is something that us done frequently, I wouldn't expect the extension block to be mounted by default.
