Review: For the price, perfect! - Based upon the build quality of my other Jet shop tools and on desertcart reviews, I selected this machine. I needed a mortising machine for a project of building 12 chairs. There are lots of rave reviews already out there, so I won't repeat all the good stuff. Just believe it! What I will do is to defend this little machine's only few weak spots, or at least the criticisms in the reviews. The main one is about the table being too small, and because it is made of MDF, "cheap." Well, the table is actually the cast iron base, and it has a piece of MDF bolted down to it to protect your chisels should you drill clear through a piece of wood. Others complain the table is too small. Not exactly sure why you would need it to be any bigger, but I had no issues with that doing 144 mortises in some pretty strange shapes of wood. The hold-down is, in fact, poorly designed, but it's such and easy fix that it is laughable. I just cut two small wedges of wood and installed them on the bottoms of the two hold-down arms (with a wrap of masking tape) so that now they press down evenly on the workpiece instead of only on the side toward the machine. End of difficulty extracting the chisel from the workpiece. For some of my pieces, to get them placed in the same spot each time, I used a drill-press vise bolted to the cast-iron table. I clamped a stop onto my work table to locate the end of the workpiece and the little vise did the rest. The three chisels that ship with this machine are incredibly sharp and worked perfectly. (I only used two of them.) The motor's power is more than ample, the machine is designed so that the pull-handle can be locked into whatever position that is the most advantageous for the situation. It does take a hefty pull, so that's important. For its low price, this is a terrific machine. I highly recommend it. BTW, it arrived from desertcart well-packaged and in perfect condition. And no, I didn't get paid to write this review; I just like to give praise when it's due! I'm giving 5 stars in spite of my only criticism, the hold-down, because it was such an easy fix, and also because had I wanted a more "perfect" mortiser, I could have paid $1000 for a professional machine. This is a tool I will not use every day, and for the price, it is perfect. I thought it was actually fun to use! Imagine drilling square holes!

## Questions & Answers

**Q: What is the size of the chuck key? Got a used one without a key, and none of my chuck keys fit.**
A: It is a special oversized chuck. It can be ordered from Jet at 800-274-6848. Part number 23011076.

**Q: What size stock fits with the fence? I know with larger stock the collumn can be rotated 180 degrees, but with the fense can it take up to 6" stock?**
A: Hi, I just measured and from the bit tip to the table it's 4".  Six inch stock will not fit.  Hope this helps.

**Q: What chisels does this come with, if any? The description says it comes with three, but I didn't see any further mention of the mortising chisels.**
A: Sorry for the delayed response. I found 3 that came with mine. 1/4, 3/8 and 1/2 inch chisels. Hope this helps.

**Q: Is this 50hz or 60hz?**
A: Mine, as delivered, is 60 Hz, 115V

Exceptional Machine - Just what I expected from Jet. Well built and worth every cent.

### ⭐⭐⭐⭐ Makes square holes
*by J***E on April 6, 2022*

It's a mortiser and it works. It's nice and heavy, feels solid. It's accurate and easy to use. My only complaint is that it burns harder woods like walnut and oak. It really feels like you have to muscle it to get it to go in, but it still works fine. But hey, I'm a hobbyist, and it works beautifully on softer woods.
