Ideal for professional furniture makers as well as for home woodworkers, Jet's affordable 708580 JBM-5 benchtop mortiser features a 1/2-horsepower induction motor and is designed to take up to 1/2-inch chisel bits. The dependable rack-and-pinion head adjustment gives you accurate drilling control, while its heavy-duty cast iron and steel construction provides durability and stability for years of use.



Dependable mortiser for home woodworkers or professional furniture makers (view larger).

Features

At only 44 pounds, the Jet 708580 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 (other models on the market often have doors made of flimsy plastic) 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.

The mortiser's feed handle adjusts so you can choose the most comfortable position for each application, and it also offers a quick-setting depth stop and a removable toggle switch that prevents accidental or unauthorized use of the tool. It's set on a heavy-duty cast-iron base with four predrilled mounting holes. Other features include a three-jaw drill chuck that keeps a positive grip on mortising bits for chisels up to 3/4-inch in size, two hinged side doors for easy access to the chuck, and a reversible column for mortising larger stock. It's backed by a 5-year limited warranty.

This is a really fun tool to use
5 Stars
This is a really fun tool to use
Morty and I are getting along fine. Right off the rip I used a Fisch Hollow 5/8" bit instead of the three gimme-bits cause you tend to get better results when you use better steel. I read all the people complaining about the hold down, and I kind of get it, but not really. It was a simple thing to add extensions by drilling/tapping some feet on the hold downs and putting some rubber bicycle handlebar end stops on them, so if that is the worst problem this machine has, it is gonna be fun living with Morty.My thought is to not use this for building furniture, but do some puzzle boxes and make a nice gun rack using square ebony pegs on a semi-rough tulip poplar board, things like that. This machine makes my ham fists into virtuosos when making a square hole as I am not gifted with a chisel in making it do what I want it to do.The bit makes noise when not cutting since the chisel and the bit are not really aligned in a super precision manner, and even if they were it would still make noise. I spray on some dry lube like moly-mist and it is good for a while. Once the bit breaks in a little, it will probably be fine. The machine is quiet-ish and the MDF base is awesome for those of us who like to make through-mortises.Yeah, this is a major splurge, but the ability to cut square holes is awesome. It was either this or a small lathe, and this doesn't take much space. I am really pumped on this tool.
