Tools and Hardware Reviews of Jet 708580 JBM-5 1/2 Horsepower Bench Mortiser

Customer Review: A Great Bench Top Mortiser
Summary: 5 Stars

After building two mission style end tables, I knew there had to be a better way than the drill press and chisel to make mortises. I did a bit of research and decided on the Jet...cost and reputation were factors. This is my 3rd jet tool...the JWSS-10 SuperSaw and a dovetail jig are the others. The machine is easy to set up, and does nice mortises. My 1/4" bit leaves a small hump on one side of the mortise...which I attribute to the bit. Unless it is a through mortise, you'd never know it was there on a finished piece. I set the hold down just a touch loose, and can easily slide the workpiece from one cut to the next. You'll need to go slow on the first cut, and back out the bit a couple of times to clear the chips. After that, you can move right along. Is this a production floor model machine? No. Did it cost [money]? No. Does it make good mortises? In my opinion, yes, and it is worth every penny of [money].

Description of Jet 708580 JBM-5 1/2 Horsepower Bench Mortiser

Mortising has never been easier or more accurate. Model JBM-5 JET Benchtop Mortiser features include: powerful 1/2 HP TEFC 1725 RPM motor for solid performance and trouble free operation, heavy-duty cast iron and steel construction for durability and stability, three jaw drill chuck with extended chuck key for ease of positive grip on mortise drill bit. Rack and pinion head raising and lowering allows for positive drilling control. Two hinged side doors to allow for complete drill chuck access. Removable safety toggle switch for prevention of accidental turn on 1/2" max. mortise chisel capacity. 4-3/4" head stroke. Includes free 1/4", 3/8" and 1/2" chisel and bit sets.
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
