All seven saws in the best table saw testing have some kind of dust control. The Rockwell saw has a completely enclosed motor compartment with a large dust bag that attaches under the saw to catch sawdust. The remaining saws have a shroud around the blade and a 2-1/2-in. port on the back for attaching either a bag or a vacuum cleaner. None were perfect, but at least you can catch most of the sawdust. The Craftsman and Ryobi also include a dust bag that attaches to the vacuum cleaner port.
In other words, a malfunction might mean an injury. This distinction could not be more pronounced in any other job site equipment than a table saw. I have personally witnessed devastating injuries on a number of occasions that could have easily been avoided by the use of safety equipment that comes standard on most brand name saws. Liability for a job site injury can be a serious setback for well established companies, but for small, independent contractors it could mean the difference between business and bankruptcy.

The body of the blade is made from hardened steel, helping to extend the lifespan and keep up with the tooth quality. The kerf is a crazy-thin 0.098 inch—narrow to keep the cuts fast by reducing the amount of material that needs to be removed. Like most Diablo blades, you’ll pay a bit of a premium up front, but the blade lasts so much longer than others on the market that the cost per cut is much lower.
We made a few test cuts with ¾-inch plywood just to get a feel of the motors we were working with. It became clear pretty quickly that not all 15 amp motors are equal. Once we knew what to expect, we moved to pressure treated 2x pine material in 7-1/2 foot lengths. Why 7-1/2? Our test material started at 15 feet and it seemed silly to have some at 8 feet and others at 6.
​The saw does not easily detach from the stand. Sometimes it’s beneficial to set the saw up as a bench-top saw, but the DeWALT 7491RS doesn’t come with quick release levers to accomplish this easily. In this case, you would have to use a drill to remove four screws to detach it from the stand. I wouldn’t recommend doing this unless you have to because over time the screw holes will strip.
The design is not bad. The height of this particular table saw is around 35 inches. While some people don’t mind it, we think it could have been designed better. However, the best thing about the design is the fact that you can get both contractor and cabinet style table saws in one unit. Dust control is well-designed. The large 4-inch dust port offers a no-hassle setup, especially with vacuums of lower quality. In simpler words, you don’t need to purchase a super-expensive vacuum for this particular unit; any affordable one should do the job well.
