Pros and cons

The workmanship of Powermatic PM701 3/4 Horsepower Bench Mortiser appears excellent. The motor is very smooth and works without any effort at all. The guides which move the table and lift the head both operate smoothly and easily. The motor is a 3/4 horsepower monster, much smoother and more powerful than the opposition products which mostly feature 1/2 horsepower motors. This machine doesn’t bog down, even in hard and green wood, like its less powerful cousins.

The spacer which is fitted for the auger and chisel bits is handy, and so is the tool rest on to the back, for your extra chisels, it also has a chisel polishing hone attached too. This Powermatic PM701 requires a 10mm hex wrench, which isn’t supplied by Powermatic, so you will need a set of metric wrenches, but this is hardly a fault is it. A depth stop allows you to level at pre-set distances, whilst the sturdily constructed handle is fully reversible, easily changed from right to left, and is great in case of a left-handed woodworker. The stock lock down includes a unique double lock, which eliminates slippage whilst removing a chisel from a job. The fence features a fast action lock for the cam, which makes positioning simple, and the chuck door is hinged and has a magnetic catch, which allows easy access to the chuck with a standard 4” key. The fence can be adjusted with the rack & pinion system.

One very small bug in the works was that the paint finish wasn’t all that brilliant. This won’t affect the massive performance of the machine at all, so maybe it’s not a problem to worry about.

Why should you buy it?

You should buy Powermatic PM701 3/4 Horsepower Bench Mortiser if you have any amount of awkward carpentry jobs to do. It is superior to the other brands on the market and appears to be built for a lifetime’s use.


Powermatic PM701 3/4 Horsepower Bench Mortiser -A good, strong product, one which will stand you in good mortising stead for many years to come. Price? For what you get, it’s low and this machine will last, unlike some of the less powerful on the market.
