You could, but it would take some adapting to do it. To put a vise on it, and we are talking about a drill press vise, you would have to take the fence off of the machine, and there is no way you could use a mechanics' vise, as they are way too tall. So, you could use a drill press vise, or maybe a cross-feed vise made for a good sized floor model drill press, but again, you'd have to take the fence off of the machine, as well as the hold down fork and post which holds it. Now you could also put the extension in place (making the rack & pinion which moves the fence useless), and use your drill press vise for the fence and hold down.

max height of adjustment

i am looking to make a table with beard board ends, will this machine fit a 5 inch tall piece?
Asked by: prc61
With the 1/2" chisel & drill, the height above the table is 4.5" above the table. The smaller size drill/chisels increase that clearance as they get shorter as they get smaller. The 1/4" has about 6" clearance from the table. If you install the 2" riser add 2" to the clearance.

If I rotate he head 180 degrees, could I use it to mortise for square iron balusters. The stairs are already buillt. I need to know if the chisel and bit can plung 3/4" below the base.
Asked by: Ken
If you are wanting to put square holes in metal, the answer is NO. For that it needs to be done by a broaching machine, or a 20 or more Ton press with a broach mounted on the press. You can buy broaches at machine shop supply companies like MSC, etc... This machine will only work on softer materials like wood and maybe some plastics, like PVC or Teflon, nylon etc...To mortiss with the head reversed, you would have to have the table bolted down onto a bench, or something. The head of the machine is also where most of the weight is.....As far as plunging below the surface level goes, I made a leg for an old dresser with 2" deep mortises, so (without knowing the specifics of your project) you'd have to compare the stroke of the machine to the depth you want to make - you may have to make a riser table to set your material on, and a way to hold it down, like a step clamp set up, or something to that effect.

There are pros and cons to each but they looked largely equivalent to me. The price on this was less which became the decider. In operation I have no complaints. I like the high fence and cast iron base. Very sturdy and stable. I don't have mine bolted down and it does not need to be. Hold down is solid. The depth stop works well. After pounding mortises by hand for years this seems too easy.

Rated 5 out of 5 by from Delta mortiser This came in just in time for a project I was working on. Two days early. It took a few minutes to set up and get adjusted but once I did it worked great. Very happy with this unit.

I have a small custom funiture business. While in the middle of a project with a tight schedule, the mortiser ( same model ) that I had owned for a long time, failed. So - ordered this one. When I began to work with the new one, I discovered that the fence was not square to the base. Since I was on a tight schedule with my project, I did not have the the time to go throught all the return procedures for a new machine. I removed the fence from the new machine and yes - it was not close to square. I took the fence off my old model, which was spot on square and put it on my new machine so I could complete the project on time. When I contacted Delta to see what we could do about some kind of compensation for the faulty machine - no help. I was refer to a "manager" of customer service who put me off for over two months with the sorriest of excuses I have ever heard. So - what I recieved from Delta was a usless machine that I had to fix to meet a deadline, and Delta, the company that makes tools for working people, could not understand and accomodate my problem. I sent pictures, made calls, wrote emails - nothin'. Delta, once a go to company for folks who wanted good tools - what a joke. I will not buy another Delta tool. I have never been treated so shabbily.

First thing to note in this review is that the machine is NOT a 3/8" machine. It is a 1/2 Horsepower machine, and will mortiss (with the drill bit/square chisels provided in the box) from 1/4" - 1/2" square holes, and works very well for this purpose. If you set up the machine by following the instruction manual, you should have no problems cutting your mortises. You could also use the machine for a small drill press, although the range of stroke is not very long, because the machine's drill chuck has a 1/2" capacity, meaning you can chuck up to 1/2", but you can also use larger drill bits 1/2 thru 1" with reduced shanks, such as Silver & Deming types...The biggest drawback with the machine is that if you install the 2" riser set up (with the other extended parts that go with it), the rack & pinion (controlled by the knob at the base) that moves the fence back & forth, doesn't work any more with out making a part to extend up the rack & pinion as well. Other than that, this is a very good machine. You can make mortises for window frames, door frames, face frames for cabinets, boxes, etc, etc. Enjoy. I've had the machine for 2.5 months, and feel that is well worth the money, and is a way better machine than the one from Harbor Freight; the base of the Delta machine is wider and deeper, and heavier, which makes it much more stable than the cheaper model.

Rated 1 out of 5 by from Extremely disappointed, housing was broken I selected the Delta over the Jet based on reviews and maybe a little on the cost. The package came and the box looked as though it had been properly handled. when I opened the box, everything seemed to be in one plastic bag. The box was so heavy I decided to unload the box piecemeal and carry to the basement for assembly. I picked up the housing and noticed the back was broken off. The package was shipped directly from Delta, and it looked to me as though the sent me an item that had been returned and not checked. I bought the Jet.

Rated 5 out of 5 by from This is a great investment for someone wanting to perform repeated quality mortising This unit is solid, and extremely heavy. However, interestingly, it requires being secured to a work surface to perform safely on larger pieces of wood; the weight of the wood and tension from the machine can lead to awkward tilting during operation. The "shelf" on the rear of the machine seems misplaced, but it does not hinder operation. A better holder for the chuck key would have been a minor, yet very helpful improvement in overall engineering. The only complaint I have about the machine is the depth stopping mechanism; it tends to slip and does not connect squarely with the main column, which can lead to varying depth over time. Like me, you may need to really, really secure the depth stopper to have it work flawlessly. Also, the stopper itself needs to be secured in alignment with the holding screw properly; the flat face of the stopper should be aligned with the holding screw, else it may rotate and shift. I do not understand the way the stopper was designed for this device; the bent part of the non-square stopper contacts the top of the column, instead of the base of the device as one would expect. Overall, this machine is an incredible workhorse, and a great value for the price. I wonder about availability of chisel and bit replacement, but the included tools are very well performing. The motor has a tendency to buckle when being fed to quickly into a workpiece; stopping the unit and turning the chuck by hand seems to clear it up easily, but I am curious about why this is so often necessary for such a powerful motor. I would recommend this machine to anyone serious enough about quality mortises to consider purchase. A drill press bit cannot compare to the overall operation and performance of this superior piece of equipment.

Rated 2 out of 5 by from not impressed Machine sets up fairly easily, but mine needed some extra attention with the mating surfaces that the head slides up and down on. They still don't line up exactly but it will suffice, almost no play now anyway. The post that the work piece holddown slides on is very rough and has to be pulled up on evenly to get it to move. In spite of what the instructions say, you will need an additional hex wrench for assembly. The lever that moves the head assembly only goes into position 2 ways. One position is too far back and the other is too far forward, making it awkward to operate. This is my first mortising machine but I certainly would have to think that other cheaper brands would be better than this one. Rather disappointed, Delta used to be an excellent brand.
