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.

The DeWalt doesn’t go above and beyond here but has some standard safety equipment as part of its Site-Pro Guarding System. The Blade Guard Assembly is a standard clear plastic set of guards that allows the wood to be fed to the blade but shields you from putting hands on the exposed blade in a slip. The guards will lock in a raised position when you need to see the blade—for example, when adjusting the blade height—which lessens the temptation to remove this safety feature when it’s in your way.

In any Dewalt DWE7491RS review, it is clear that its drawbacks are minor. The throat plate lock could do with a bit of quality work. Also, if the dust port offered effective use with an accessory package or so, the dust cleaning would be much more ideal. The best part is, these issues are a trade-off, considering the overall performance. You can purchase it without hesitating.
The built-in stand sets this saw apart from competitors since it is actually quite stable out of the box and doesn’t require a custom stand or supports to combat vibration, which are often necessary with cheaper and lighter units. DeWalt sells a nearly identical saw with a less robust stand, and after viewing it in a big box store, I was glad to have this one.

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.

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.

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).

What is a fence? How important is it in a table saw? It gives you an option for horizontal or vertical adjustments. A good rip fence should be aligned to the blade at all times. Without a fence, everything will be disgusting. Ensure that it is heavy and that it can glide smoothly across the rails. Also, make sure that the locking mechanism is perfect and convenient.

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.
