For you furniture makers out there who find yourselves spending more time than you'd like setting up the mortising attachment on your drill press (then taking it off, again), JET's affordable benchtop mortiser ought to be a welcome addition to your woodshop's tool collection. Designed to take up to 1/2-inch chisel bits, JET's benchtop mortiser runs off a 1/2-horsepower induction motor. At only 44 pounds, the tool is sturdy but also easily maneuvered, plus it reverses on its base to allow for mortising in long stock. The 4-3/4-inch head stroke is great. Bits are easy to change. Just flip open the steel door on either side (these doors are made of flimsy plastic on some of the competition's models) to gain easy access to the chuck. And, thanks to the 4-inch chuck key, there's little chance of banging or scraping your knuckles while switching bits (a small touch, perhaps, but a nice one). We also like the quick-setting depth stop on this tool--as well as the removable toggle switch that keeps less-experienced (or child-size) hands out of harm's way. The mortiser's feed handle adjusts, too, so you can choose the most comfortable position for each application--another nice touch. Set on a heavy-duty cast-iron base with four predrilled mounting holes, this dependable machine allows any woodworker, from the beginner to the expert, to create fantastic-looking mortise-and-tenon joints. --Justin Paul

This review is from: Jet 708580 JBM-5 1/2 Horsepower Bench Mortiser (Tools & Home Improvement)
If you utilize mortise and tenon joints and have been creating them with a router or a drill press with a mortising attachment, you will really enjoy this product. There are several positive attributes about this tool and one negative.

Positive Attributes:
1) HP is quite adequate.
2) The chisels and bits I received were very sharp. They believe that they would serve the non-professional well. I usually use Clico bits, but I recommend that you at least try these before you purchase an expensive set. You might be as pleasantly suprised as I was and you could save yourself some money.
3) Fit and finish is very good.
4) The column mounts to the base structure with capscrews. The Jet engineers were thinking, because they provided two assembly hole patterns. The second hole pattern allows you to turn the head around 180 degrees. This will enable you to mortise stock one or two inches taller than normal designed capacity without a major setup...Read more

5.0 out of 5 stars JET Benchtop Mortiser is Tops!, March 23, 2000

This review is from: Jet 708580 JBM-5 1/2 Horsepower Bench Mortiser (Tools & Home Improvement)
After having used biscuit joiners, dowels, and hand-made mortise and tenon furniture, I decided to invest in a powered benchtop mortising machine. After seeing and using various brands, I found the JET JBM-5 to be the best designed and most precisely built of the lot. The machining, design, simplicity of use are the best available for the novice-to-advanced woodworker. The hold-down bracket is designed to clamp evenly and the depth stop is easily adjusted without tools, unlike the Delta model. Another useful feature is the unit can be reversed on its base, allowing mortising of long objects--I built a clamping devise on the back of my mortising stand and can accomodate 36" long material for end-mortises or wide stock. The 2 year warranty should be more than adequate, given the history of other JET tools I've used--all running prefectly as designed.

5.0 out of 5 stars Love that mortiser, April 30, 2000

This review is from: Jet 708580 JBM-5 1/2 Horsepower Bench Mortiser (Tools & Home Improvement)
I have a Delta drill press and had used a mortising attachment for several years. It is quite difficult and time consuming to set up. I had wanted a dedicated mortiser and decided to try the Jet, and boy am I pleased. Basically, right out of the box you are ready to make great mortises. I attached it to an auxilliary table as described in the manual and began work. I am building an antique pie safe and am using very hard red oak lumber. The Jet tooled through the red oak like cutting through butter. I especially like the slow speed (1750 RPM) that the drill bit turns. You are assured that you will not burn the wood. The chisels are also incredibly sharp. I found it easy to set the work fence to center the work piece and properly setting the cutting depth adjustment is a breeze. All in all, a very fine tool. Very glad I bought it!
