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.
Both saws were almost equally quick to setup for use, with the DeWalt coming out slightly ahead. The throat plate, which is thicker and sturdier than Bosch's, is slightly easier to remove and reinsert. The DeWalt's blade cavity offers greater clearance, which makes locking down and loosening the riving knife easier without scraping a knuckle. Dewalt's riving knife adjustment required less wiggling and hunting to get it set properly.
About three paces from where I tested these portable table saws sits my late-model cabinet saw. As a serious woodworker and magazine editor, I can’t imagine not having it. Its powerful 3hp motor, spacious cast-iron tabletop and almost hair-splitting precision makes most other saw options pale by comparison. But all this said, a cabinet saw isn’t everything. The thought of moving that behemoth down the steps to a basement shop sends chills up my spine. I sure can’t toss it into a car trunk to help a friend down the road. My saw takes up a huge footprint of shop floor, and it cost a small fortune. I don’t know of any stationary table saw that sells for less than $700 new these days, and that can empty the coffer of a modest tool budget.
You can’t talk about the best portable jobsite table saw without talking about portability. Portability boils down to a couple of important features. First and foremost, weight has a huge impact on how easily you can transport the saw, especially if it has to go into the bed of a truck rather than a trailer. If you’ve got a trailer, then a wheeled stand becomes your best friend. We looked at both.
It has a machined aluminum table which is extremely precise. We like the Dewalt’s cast metal table for the price, but the company don’t list the material, and we suspect it’s not nearly as rugged as aluminum. The Bosch’s table is much better. It’s rugged, sturdy, and more consistently even than the Dewalt. The table makes this one a smarter choice for fine woodworkers or pros who need superior alignment.
Table saws will use one of two different kinds of drive configurations; Direct-drive motors and Belt-drive motors. In a direct-drive motor, they will link directly to the blade itself and transfer all of the power of the motor to the blade. They tend to last longer than belt drive motors and there is no belt to replace or worry about getting worn out. Belt drive motors transfer power from the motor to the blade through a belt. In this type of configuration, the motor can be offset away from the sawdust which helps the motor last longer. In general, belt drive motors need more preventative maintenance than direct-drive motors do. If you have a belt drive motor, check the tension of your belts as well as checking them for wear periodically to ensure your continued safety.
The SawStop Contractor Saw CNS175-TGP36 stands out chiefly on account of its unique safety brake, which stops the spinning blade dead when it senses the presence of skin. However, it's also an excellent saw in other respects: powerful, well built, and easy to assemble, with great dust collection and loads of features. Cost is a major concern, but so is the cost of the injuries SawStop is designed to eliminate.
One very popular alternative to the Dewalt is this Bosch unit. It’s a bit more rugged than the yellow saw, and it’s very well-regarded by working woodworkers. We particularly like the machined aluminum table, which is a big step up from the Dewalt’s molded surface. It also has the best rolling stand we’ve seen on the market to date, so it’s a superb choice for folks who work on a lot of jobs sites with mixed terrain.
It is not a cabinet saw, so judging it by those standards would be unfair. As a portable job site saw this is amazing. Loud and dusty, sure, but that is expected. Easy to use and store, yes. The fence is square to the blade, and is rock solid, as long as you make sure the nut at the back of the fence is set right. The fence is not quite square to the table top, and I can't tweak it, but for construction I wouldn't care. I do other fussier things on the saw, so I will shim out an auxiliary fence. I made a cross-cut sled, which I recommend, and get thin kerf blades. I got a rip, general, and fine finish blades, and I get great results.
Not everyone needs to use the miter gauge on a table saw since there’s typically going to be a miter saw around. If you do, you’ll like the positive locking detents at common angles. This saw felt like it was the weakest when pushing our 2x PT material through. Despite the ranking, it doesn’t feel under-powered – you just need to take your time. You won’t find a lot of bells and whistles on this model, but for $279, we don’t have many complaints.
The most critical safety feature on a table saw is the blade guard. It’s all that separates your fingers from the rapidly rotating blade. You need this to be transparent or it will make measuring awkward. The last thing you want is to be tempted to remove an unfit guard. Check closely for a clear, flexible blade guard. Safety is paramount when operating a table saw.
With a 32½" rip capacity and motor capable of up to 4800 rpm, the DWE7491RS is more than prepared to effectively deliver 3⅛" deep cuts to thick slabs of wood. Happy customers sing this machine’s praises, reporting that it’s as sturdy as a table saw can get — plus, it’s easy to use, and assembling it is a cinch. They do however note that workers looking to produce finer cuts should seek out a replacement blade since the one provided is more suited for fast, rough work.
