Upon unboxing, I wasn’t sure how much I cared that the built-in stand for this saw had wheels, but, boy, did I ever use them. If weather rolled in, the saw folded up and rolled to shelter in the garage. This was extremely convenient since I did my cutting in the driveway and stored the saw in the garage overnight. This maneuverability might be less useful to you if you plan to use the saw primarily in your garage where you could build or buy a semi-permanent stand rather than use the fold-up stand of this model. There is also on-board storage for the power cord and the loose parts such as the miter gauge and guards, making it completely self-contained.
This particular table saw features a high-torque motor of 15-amp, which is suitable for cutting hardwoods as well as the pressure treated timber. This is also aided by a speed of 4800RPM. The tool also features a rack, as well as a pinion telescoping fence rail that creates accurate, meticulous, and smooth fence adjustments. You can flip over the fence to make small and precision rip cuts.

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 “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.

As with many table saws, the included plastic miter gauge isn’t nearly as precise as the fence and so I made angled cuts on a miter saw. If you are hoping to use this saw in lieu of a miter saw, you’ll probably want to invest in a higher-quality third party miter gauge. You can also attach a vacuum to this saw’s dust collection port for easy cleaning.

Hey all. I just got this saw upgrading from few previous model. I thought this is the best potable table saw. I assembled all and I began adjusting blade squareness. I squared on the left side of blade and thought it’s good but guess what, when I put a square on the other side of the blade it was way out!! I said myself NO WAY! Checked few more times but same result! So I put my 4foot level across the table. OMG! It was a cup towards its middle by almost 1/16″!! WTF!! I just could not believe my eyes!! I am a pro carpenter and long time Dewalt lover but now I am sooooo disappointed what I just saw. I’m gonna write Dewalt and see what they say about it.
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.

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).

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.
