Cutting dadoes can be done with a dado stack blade. I use the Freud 208. Blade changes are easy, and there is a lever that locks the blade in place so I can get a good yank on the nut with the included (and stored onboard) wrench. There is an accessory throat insert for the dado blade stack, but the standard throat will easily handle a ¼ thick stack, which is what I usually use.
If you’re a home DIYer, dust collection shouldn’t be a big worry. You can always hook the saw up to your shop vac, but if you’re only working with it occasionally, you’ll be fine to simply get your sawing done, and clear the exhaust port afterward. However, if you’re working on a professional jobsite, you should plan to collect at least most of the dust from your portable table saw via a vacuum system.
Look for a blade guard and splitter assembly. The guard will keep your fingers and sleeves away from the blade, while the splitter will keep your wood from re-binding together and jamming the blade, or causing kickback. Kickback is one of the biggest hazards of using a table saw, aside from coming in contact with the blade. Make sure you have either a splitter assembly or a riving knife on any cabinet saw you use.
Kobalt’s KT1015 Table Saw features value pricing with a decent rolling stand. We initially had questions about its dual-locking fence, but found that it actually worked quite well. There’s plenty of wobble in it, but if you follow our Pro Tip on adjustments in the fences section, you can lock the front end in square then stabilize it with the back lock.
The DEWALT DW745 and the Bosch 4100 are pretty evenly matched in having plenty of power and not-so-hot dust collection. I you’re looking for a light weight saw, the DEWALT comes in ahead since it weighs almost half as much as the Bosch. It is also the less expensive choice by far. The large work table, expanded cutting capability, and its Gravity Rise feature (with solid rubber wheels that make it easy to be rolling across rugged terrain at a jobsite) make the Bosch a Cadillac among Pintos, but, of course, that luxury comes with a price tag.
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.
