Prior to deploying the power loss reset feature there had been many job site horror stories of unattended table saws starting up upon power restoration.  Sometimes this restart caused material damage or personal injury.   This usually happened when the saw operator did not think to turn off the tool before walking away to go restore power. In the meantime, other people have leaned on, temporarily placed tools or even building materials on the saw, a blade spinning disaster waiting to happen.
The blade is adjustable from 0-45 degrees for a variety of bevel applications. This DeWalt Table Saw has a 15-amp motor for cutting hardwood and even pressure-treated lumber. This will let you make cuts to a depth of 3- 1/8 inches at 90 degrees and 2 – ¼ inches at 45 degrees. Other important features include a coated table surface and a metal roll cage to protect the tool. This weighs 45 pounds and therefore it is easy to lift and take to your workspace or at the worksite.

DEWALT’s recent release of three new job site table saws is capped off with the all new DWE7491RS. This 10″ job site table saw with roller stand is their premium offering. We recently also reviewed the DWE7480 and DWE7490X which were released with this saw. The DWE7491RS is very similar to the DWE7490X except that it has a larger rip capacity and a much nicer stand.
Smaller, portable table saw models have direct-drive motors that can operate on 120 V power to produce 2 HP. This is enough motor power to take on thinner materials. Table saws with more powerful motors are usually stationary saws that produce between 3 to 5 HP. Table saws with stronger motors rely on a belt drive to transfer the power from the motor to the blade and these operate on 240 V.

Accessory Storage – DEWALT clearly made an effort to make it easy and convenient to store the accessories including the blade guard. One of my pet peeves on the job site is asking the crew where they put the guard. Typically it gets removed for some cross cutting or dado’s and then never makes it back on the saw. Having a dedicated storage location for the guard makes that much less likely to happen. There’s a place to store the wrench, guard, riving knife, miter gauge, and the anti-kickback knives.
The first problem I had was trying to outfit some sort of “Y” and hose to tee off my main dust port and attach to the upper one (2-1/2″ to 1-1/4″ “Y’s” are not that common). Then, if the smaller hose on top doesn’t fall to the side, it interferes with the wood you’re trying to cut. After talking to the product manager it sounds like this detail evolved in Europe and found it’s way here. I’ve basically abandoned the upper port and just use the lower one. Cool idea, but it needs some serious redesign and/or an accessory to help make it easier to hook up.

Typically sold for around $600, the DeWalt isn’t exactly cheap, and you can find similar portable table saws for less. DeWalt itself has several other jobsite table saws for lower prices, though they either lack a stand or feature a flimsier one. However, if you value a sturdy stand and the ability to wheel the collapsed unit around, it’s easy to justify the modest extra expense for this saw.

The shark fin-style riving knife behind the blade keeps cut pieces from binding and causing kickback. The included push stick is useful when using thinner workpieces that don’t allow your hand to be at least 4 inches from the blade. The power button’s flip cover ensures that you only turn the blade on when you mean to, which is a welcome layer of safety.
