Buying a table saw covers a lot of bases. You have everything from entry-level models to professional production level cabinet table saws. In this article, weโre looking at the most popularโjob site table saws. These highly portable saws fall on the less expensive side compared to their cabinet saw counterparts. That makes them the go-to tools for framers, job site carpenters, and even DIYers.
Features aside, itโs the blade that does the work. So no matter what features you need, start with a quality table saw blade. After that, set the optimal table saw blade height, and youโre much more likely to get a quality product in the end.

Buying a Table Saw for Jobsites
Motor Power
As you might imagine, table saw power increases from benchtop through cabinet models. Looking specifically at jobsite table saws narrows things down considerably. Buying a table saw for jobsite use, youโll want a 15-amp motor. Thereโs plenty of ripping power, and you only need 120V AC power.
The first cordless table saws are making their way into the industry. However, we donโt have a viable replacement for the 10โณ table saw just yet. Youโll still get the best performance with corded power.
Direct Drive Motor of Belt Drive
The vast majority of job site table saws use a direct drive motor. Youโll typically only find belt drives in more powerful cabinet saws. There is a twist on jobsite models, however. Skilsaw has two models that use worm drive motors. They have the lightweight Skilsaw SPT70WT-22 and the heavy-duty Skilsaw SPT99-12 table saw.
Table Saw Blades
The standard table saw blade diameter is 10-inches These will give you somewhere around a 3-1/2โณ cut capacity at 90ยฐ. Many cordless table saws running around have blades in the 8-1/4โณ range. These require you to give up some cutting depth. If you need maximum depth, you get more versatility out of a table saw with a 10โณ blade.
Blade RPM | Speed of Cut
For benchtop and jobsite saws with direct drive motors, the motor RPM is the blade RPM. If youโre considering a contractor or cabinet saw, itโs a different story. In any event, professional table saw blade speeds generally fall between 4000โ5000 RPM. Donโt let numbers on the lower side dissuade you. Thereโs a limit to how much power you can draw and each manufacturer has to decide how theyโll channel it between blade speed and torque. So higher isnโt necessarily better.
If youโre on the carpentry side of jobsite table saw use, a lower RPM can actually help you. High speeds can burn hardwoods or require faster feed rates as the blade cuts. Lower speeds help alleviate those issues.
Blade Arbor
The arbor and trunnion hold the blade and allow it to move up, down, and at angles. Their quality increases with saw power and price. The arborโthe shaft that holds the blade in placeโalmost always measures 5/8โณ on jobsite table saws. Just double-check the size before buying blades.
The Table and Ripping Fence
When buying a table saw, tools made for jobsites use an aluminum table. The lighter weight makes them much more portable than shop saws with a cast iron table.
A quality table saw requires a fence system that remains perfectly square to the table. This keeps your cut perfectly parallel to the edge. Obviously, framers have a bit more leeway than job site carpenters and thereโs plenty of variance in fence quality. Cheaper saws have fences that can easily move out of square as they slide along the surface of the table. Avoid these if you want quality results. The fence system needs to be easy to keep square to the blade.
One of our favorite systems is the rack and pinion design of Skilsawโs heavy-duty model. A couple of other brands also use the same concept. Since the fence locks in place and the table does the moving, you donโt get the slight misalignment that comes with fences that clamp onto the table.
Rip & Outfeed Capacity
When choosing the best table saw for job sites, youโll need a rip capacity of more than 24โณ. Why that number? 24โณ is half the width of sheet material. Some models will give you as much as 35โณ. Since you ideally want to have the waste edge opposite the fence, the larger the capacity the better. But again, jobsite table saws are designed for Pros with a little more inherent forgiveness in the job. Presumably, you can cut the waste edge against the fence if necessary.
Outfeed capacity is almost always the depth of the table. Pros using a jobsite table saw can opt to put a sawhorse or other support to hold the material after it passes the blade. A few models on the market give you some extra outfeed support. Most of the time, however, youโll just have a buddy help guide the cut-through from behind the saw.
Throat Plate & Dado Stack Capacity
The throat plate is the removable piece surrounding the blade that sits flush with the table. Removing it gives you the ability to access the blade for removal or riving knife adjustments. The narrower the blade clearance the better for two reasons. First, it helps keep material from falling into the blade area or lodging between the blade and throat plate. Second, it gives you material support very close to the cut to help reduce tear-out as the blade exits the cut.
Framing work is full of rougher cuts that rarely make use of more than one blade at a time. But occasionally you might need dadosย for an onsite custom built-in. If that sounds like you, find out the sawโs dado stack capacity. It requires a longer arbor, and you wonโt be able to use your normal throat plate for it. Some manufacturers offer a dado throat plate if they have the capacity for it.
Miter Gauge
Youโll make most of your miter cuts on a miter saw. But when the material youโre cutting exceeds a miter sawโs cross-cutting capacity, you turn to your table saw miter gauge. These usually arenโt quite as precise, but some manufacturers put more thought and robustness into it than others. If you make a lot of long miter cuts, be sure to pay attention to this accessory.
How to Buy a Table Saw with Dust Collection in Mind
Dust collection can seem like an afterthought when buying a table saw for the jobsite. Often when working outside on an unoccupied site, dust collection seems unnecessary. Inside a shop, however, things change.
Breathing sawdust doesnโt do your lungs any favors. Thatโs why dust collection is so important. Of course, when working inside or in an occupied structure, collecting all that dust also makes cleanup easier to deal with. Since weโre not talking about concrete dust regulations, even a standard shop vac works great to help contain the mess.
Safety Features
Youโll find a riving knife on every modern table saw. This helps prevent kickback that occurs when the material pinches along the back of the blade. Youโll also get a push stick to help keep your hands away from the blade. Knowing how to safely use a table saw involves using these tools.
One of the first things many Pros do is permanently (and intentionally) lose the blade guard and anti-kickback pawls. While often a pain to install and store onboard, they significantly reduce the risk of injury due to kickback. Table saws are responsible for thousands of injuries every year, and there are plenty of folks running around with stories of how they got injured. So practice installing them until it feels natural and then actually use them onsite.
Another safety feature to look for is a blade brake. Youโll know if yours doesnโt have one. The blade will continue spinning for what seems like forever before it finally stops. Having a blade brake gives you an extra layer of protection, although it still takes a few seconds to completely stop.
How to Buy a Table Saw Conclusion
Finally, a couple of job site table saws include flesh detection to drop the blade out of the way if it detects contact with a finger or arm. Thereโs a significant premium in cost for these saws. There has also been plenty of litigation regarding whether it should be required on every table saw and whether more than one company has the right to manufacture the mechanism. But theyโll save you a much worse injury in the event you touch a spinning saw blade.
