Apart from some short reviews, we’ve also covered some other aspects such as safety and proper use of these tools. Make sure you thoroughly read our articles because they could save your life. The tips we offered are well-known among the professionals, but beginners are always susceptible to various risks, especially if they don’t know how to handle these tools properly.
We evaluated the flatness of the table by measuring the flatness by placing the edge of a precision ground flat bar across the table and placed feeler gauges in any gaps to measure any difference between the ground bar and the table. TBB took measurements in four directions. As the operator faces the saw, we measured the flatness at the arbor from front-to-rear; we measured the left-to right flatness at the arbor; we measured the flatness from the upper left-to-lower right table corners; and, finally, we measured the upper right-to-lower left flatness between the corners.
The DEWALT DW745 and the Bosch 4100 both have 15 amp motors, so power shouldn’t be a problem with either of these job site table saws. The DEWALT has a high torque motor that is capable of delivering a no-load speed of up to 3,850 rpm. The Bosch 15 amps and a no-load speed of up to 3,650 rpm. The difference between the two is not something that would be noticeable without sophisticated equipment, and will not affect performance in any significant manner. The noticeable difference between the two is that the Bosch 4100 comes equipped with a soft start motor that is lacking on the DEWALT DW745. This will cause a noticeable load on your power source, and may affect other tools and lighting attached to the same source during startup.
We absolutely love the guard on this model. Like the Grizzly, the Jet is equipped with a riving knife or splitter, a blade guard, and kickback awls. The Jet’s our favorite of the two to use, because the whole system is modular: you can take it apart or put it back together without using any tools! The splitter (or riving knife) attaches to the same arbor component as the blade, so no matter how you bevel, and no matter what size blade you use, the splitter always lines up without needing any adjustments.
A 50 rpm deviation at those speeds is approximately 1% variance which is well within the tolerance we should expect from taking the readings at a precise instant of time. The meters were in constant motion and we took the reading off of a single video frame that represented our determination of no-load speeds. We report them as our instruments showed them. 1% is acceptable.
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.
