Product details:

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!
