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.
At first glance, the Bosch 10-Inch Worksite Table Saw may seem to be nothing exceptional. However, it's powered by the best motor in its class, and it does everything well. True, the motor is a 15 amp unit like the others on our list, but it produces 4 HP where the others produce only 1.5 to 2 HP. This is a noticeable step up in a vital area! The wheeled frame is extremely helpful for moving around your shop or garage, but keep in mind that those tires aren’t heavy-duty; you have to be careful with them on a worksite littered with nails and screws.
Often called benchtop, jobsite, or worksite saws, portable table saws are typically made of lightweight materials, such as an aluminum table top, so that they’re easy to move from place to place. Sometimes they’ll have wheels attached to make shifting them around even easier. The motors on portable saws are also much smaller than on other types of table saws, and are typically less powerful.
I can’t tell you how many times we’ve pulled out other jobsite saws only to have accessories fall off, or require off-tool storage. Bosch designed the GTS1031, however, to securely hold all of its accessories, even including the arbor wrenches (both of them) and an allen wrench for adjusting the riving knife and dust ejection points among other things. Our favorite was the rip fence, which simply flipped upside down and stored underneath the table – clever! About the most difficult adjustment was the riving knife, which is a tool-less maneuver, but one which requires you to stick your hand way into the blade cavity to reach the release lever. When making any adjustments to the blade, it goes without saying (but we’ll say it anyway) to disconnect power to the saw as a precaution.
