Blades come in various types and sizes. There are rip blades for cutting along the wood grains, hollow ground blades ideal for various materials, crosscut blades suitable for smooth and precise cuts, and combination blades for that double up as blades for crosscutting and ripping. Depending on what you do the most, it’s necessary to choose the right blade type and size that will get the job done with the most ease.

Further testing showed that the red “Stop” lever was the cause, not the power switch.  After turning on the saw, the red stop lever would drop too hard onto the stop button and turn the saw off.   After conferring with the product manager at Dewalt, it was determined that the red stop lever spring force was too high.  The units we tested was from a “manufacturing sample lot.”  MSL’s are the first time the plant does a big run of the product and Dewalt then has time to refine and make adjustments, before the tool goes to production.

Now I am supposed to box it up (an enormously difficult task in itself because how tightly it is packed), somehow pick up a 110lb 4′ x 3′ x 3′ box (with weak cardboard that tears if you use the included handles) on my own to put it into my vehicle, drive to the nearest store (an hour round trip), somehow get a 110lb 4′ x 3′ x 3′ box out of the vehicle, lug it into the store, wait in line to return it, then presumably wait while another one is shipped to me (the local store has none of these in stock).

The Dewalt Cordless 8-1/4” Table Saw power switch is located on the front, lower left area of the saw and has a large red stop switch that can also be accessed easily with your knee. The power switch is electronic and the saw operator now has to push a green “on” button as opposed to pulling on the “red” power lever as was the case with older models.  The power switch also has a flip over safety cover that can be secured with a pad lock. The padlock hole diameter requires a ¼” maximum diameter padlock

Performance – The DWE7491RS performs very well. The rack and pinion fence rails are the key to this saws accuracy and overall performance. The fence is easy to adjust and stays parallel to the blade. The unique fence design rides on rails at both the front and back of the saw, eliminating the possibility of fence drift. This saw also comes with a miter gauge for cross-cutting. The miter gauge isn’t all that great but it gets the job done.

At the Dewalt media event I inquired whether an accessory power cord was in the making, so users could plug into a power outlet for AC current.  Having both options would be nice. The dual option would be handy on construction sites with no power.  On these sites contractors often compete with extension cords for a generator outlet.  Having a cordless option for these situations would be amazing, later on, when the house has power, you could plug in.
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.

The “Work Support / Narrow Ripping Fence” option is a nice addition and one that I have come to enjoy on Dewalt saws.  When used as a support feature it helps keep boards wider than the table top from dipping down when the fence is extended. When used as a narrow rip accessory it provides an extra 2-inches of clearance between the blade and the fence. This helps keep you hand further away from the spinning blade.

Regular table saws usually have powerful motors that can give you of 3 to 5 HP at 240V. Powerful benchtop saws such as these can take larger materials like wooden flooring, logs, and lumber. On the other hand, smaller and more compact table saws have direct-drive motors that run on 120 V power at 2 HP. This kind of saw will work with thinner materials like wooden panels, vinyl, laminates and thin metal sheets.
I only have two minor concerns with this saw but they are so small that this saw still gets a 5 star rating.  DEWALT could step up the game on the dust collection if they offer users an effective way of using the dust port on the blade guard. Maybe they offer an accessory splitter and hose package. My other concern is the plastic parts on the fence where it connects to the table. I suspect those parts could break when they are cold if you remove the fence and toss it in the trailer or back of your truck. Again, these are minor in comparison to the rest of the saw (food for thought on the next design).

The roller stand that comes with the DWE7491RS is extremely effective and easy to use. One of my biggest concerns when buying a job site table saw is mobility and ease of set-up for one person. Weighing 90 lbs, saws like these can be a serious lifting hazard for one person. So having a mobile solution that allows a single worker to set this saw up is a hugely important issue for me and many other users.

Thanks for the response. I went to Lowes and checked several fences on Dewalts and they are all bowed about the same. But I measured the bow using feeler gages and it’s only about .008 inch, so not really a big deal. Interestingly, the Bosch jobsite saw was perfect for that particular feature. Like you said, stock will hit at the bottom of the fence and for very fine work, I’d probably be using the fence extension which is flat. I just made a picture frame today which requires accurate cuts and along with my Incra miter gage, the saw did a beautiful job. I do love how easy the fence is to move and adjust. I used my dado stack which worked fine. I also made a zero clearance throat plate. What a great tool, all in all.

About the setbacks, only a few users have cited that the dado blade is hardly accommodated perfectly and that it features a flat-track gauge instead of a T-track, which might not keep the miter gauge appropriately in place. Other than that, this table saw is popular and it enjoys good reviews. So, if you value efficiency and meticulous works, this is the saw you should get.
