How many teeth a saw blade has will determine how smooth the cut is. Most blades have from 24-80 teeth. The exceptions to these blades are specialty material specific blades (i.e. for masonry) In general, the more teeth a blade has the smoother the cut will be. The higher tooth count means that the cut speed will be slower as well. You cannot overcome a slower cutting speed by pushing harder on the material. This is a common mistake newbies make. All this will do is cause kickbacks when the saw blade catches and tosses the object back towards to the user at dangerously high speeds.
Having only owned saws with cast iron tops this is a new experience for me. First let me note that the right side extension is not aluminum like the rest of the top. It is steel, painted to match. The entire top appears to be powder coated with a textured grey coating. No telling how durable it will be but it does allow wood to slide easily over it. Since the top is aluminum, it lets you know that by transferring all the motor noise and vibration throughout the saw. Not a big deal really but definitely different if you are used to the cast iron absorbing much of this on bigger saws.
At a compact 45 pounds, the DEWALT DW745 Compact Jobsite Table Saw is the lightest table saw in our review. The saw's portability doesn't mean that ripping size is compromised, though. Thanks to extending fence guides, you've got 20 inches available. Depth of cut is on par with many bigger machines: at 90 degrees, it's 3 1/8 inches. At 45 degrees, it's 2 1/4 inches. Power comes from a 15-amp motor with a no-load speed of 3,850 RPM. This is ample enough for serious DIY projects and light-duty construction site work.
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 Shop Fox W1819 also comes with a miter fence with flip stop which provides excellent workpiece support and is great for longer workpieces. As for the flip stop, it’s going to be very useful especially when wanting to make several cuts of the same width. If you want to cut longer workpieces, you can also flip it out of the way and then pivot it back down in order to make more cuts at the cutting width of your choice.
When your skin contacts the blade even slightly, the charge transfers, and a switch flips on the motor, activating an instant brake. The aluminum brake swings into contact with the blade, stopping it instantly. The brake also propels the blade down through the arbor, so it retracts completely below your worktop. That means that other than the initial contact, you won’t touch the sharp edge at all.
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.
