JET JFM-5 Hollow Chisel Mortiser  
 
 
 
Cutting accurate mortises can be a challenging task. The JET JFM-5 
Hollow Chisel Mortiser is designed to produce extremely accurate 
mortises in a wide range of woods and project designs, plus make this an 
easy task for the woodworker. The JET JFM-5 Hollow Chisel Mortiser 
has been designed and built to extend its value by maintaining its 
performance for many years under the demands of even busy 
woodworking shops. 
 
We begin with a heavy-duty cast iron and steel frame for stability, 
accuracy and repeatability – not to mention long-term durability. 
Precision machining insures accuracy and smooth operation. The liberal 
use of cast iron gives the JET JFM-5 Hollow Chisel Mortiser a 
stabilizing mass of 267 pounds. 
 
The massive powerhead casting slides on oversized dovetail keyways 
that feature easy to use Gib screw adjusters that allow the user to 
compensate for tiny amounts of wear should that occur in years to come. We also applied Gib 
screw adjusters to the X –Y material table motions to provide ultimate control over feel and 
long-term accuracy. 

The JET JFM-5 Mortiser is 

as tough as it is accurate 

and versatile.
