Hey there, fellow DIY enthusiast! If you’re anything like me, you love the idea of tackling home improvement projects with tools that make your life easier. That’s why I’m so excited to dive into the world of the DeWalt Cordless Table Saw 20V today. This tool is a powerhouse for anyone who wants precision, portability, and the freedom to work without being tethered to a power outlet. Whether you’re building a deck, crafting custom furniture, or just cutting plywood for a quick repair, this saw has a lot to offer.
I’ve spent time exploring its features, testing it out in my workshop, and researching what other users think, so let’s break it all down together. By the end of this article, you’ll know why the DeWalt Cordless Table Saw 20V could be your next must-have tool.
Why Choose a Cordless Table Saw?
Let’s start with the big question: why go cordless? When I first started woodworking, I relied on corded tools. They were powerful, sure, but dragging extension cords across my garage or job site was a hassle. Cordless tools, like the DeWalt 20V table saw, give you freedom. You can set up anywhere—your backyard, a remote job site, or even a friend’s house—without worrying about finding a power outlet.
The DeWalt Cordless Table Saw 20V is part of DeWalt’s 20V MAX system, which means it runs on the same batteries as many of their other tools. This is a huge plus for me because I already own a few DeWalt 20V tools, like a drill and circular saw. Sharing batteries saves money and space. Plus, cordless saws are lighter and easier to move around, which is perfect for small workshops or projects on the go.
Another reason to love cordless? Safety. No cords mean fewer tripping hazards. I’ve had moments where I nearly tripped over a cord while focusing on a cut—not fun. With a cordless table saw, I can focus on my work without distractions. But don’t worry, cordless doesn’t mean weak. The DeWalt 20V table saw packs enough power to handle most home improvement tasks, from cutting plywood to trimming hardwood.
Key Features of the DeWalt Cordless Table Saw 20V
Now, let’s talk about what makes this saw special. I’ve used the DeWalt 20V MAX 8-1/4 in. Table Saw (model DCS7485), and it’s loaded with features that make it stand out. Here’s what I’ve found most impressive:
Brushless Motor for Efficiency and Power
The saw has a brushless motor, which is a game-changer. If you’re not familiar, brushless motors are more efficient than traditional ones. They generate less heat, use less battery power, and last longer. When I’m ripping through a stack of 2x4s, I notice the saw stays cool and doesn’t bog down. It spins at 5,800 RPM, which is plenty for clean, precise cuts. Whether I’m working with soft pine or tougher oak, the motor handles it with ease.
Compact and Portable Design
At just 48 pounds, this saw is easy to carry. I can lift it with one hand and toss it in my truck for a job across town. The metal roll cage base adds durability without making it too heavy. I’ve taken it to a few job sites, and the compact size fits perfectly in tight spaces, like a small garage or a cluttered basement workshop. It’s also got onboard storage for the blade guard, fence, and push stick, so I don’t lose parts when I’m on the move.
Rack and Pinion Fence System
The rack and pinion fence is one of my favorite features. It’s smooth and precise, letting me adjust the fence with a simple turn of a knob. No more tapping the fence with a mallet to get it just right! The fence extends to a 24-inch rip capacity on the right side, which is enough to handle 4×8 sheets of plywood. I’ve used it to cut large panels for cabinets, and the fence stays locked in place, ensuring straight cuts every time.
Battery Life and FlexVolt Advantage
The DeWalt 20V table saw can run on a standard 20V MAX battery, but it really shines with a FlexVolt battery. These batteries switch between 20V and 60V depending on the tool, giving you more power and runtime. In my tests, I ripped about 160 linear feet of 2x4s on a single 6.0Ah FlexVolt battery. That’s impressive for a cordless tool! For heavier jobs, I keep a spare battery on hand, but for most DIY projects, one battery gets me through the day.
Safety Features
Safety is a big deal for me, especially after a close call with a kickback years ago. The DeWalt 20V table saw has a power-loss reset feature, which prevents accidental restarts if the battery dies mid-cut. The blade guard and riving knife are tool-free, so I can adjust or remove them quickly. There’s also a push stick that stores right on the saw, which I use for narrow cuts to keep my hands safe.
Here’s a quick table summarizing the key specs:
| Feature | Details |
|---|---|
| Blade Size | 8-1/4 inches |
| Motor Type | Brushless, 5,800 RPM |
| Rip Capacity | 24 inches (right), 12 inches (left) |

How the DeWalt Cordless Table Saw 20V Performs in Real Projects
I’ve put this saw through its paces on a variety of projects, and it’s never let me down. Let me share a few examples to give you a sense of what it can do.
Building a Backyard Deck
Last summer, I built a small deck for my backyard. The DeWalt 20V table saw was perfect for ripping deck boards and cutting railings. I set it up right in my yard, no extension cords needed. The 24-inch rip capacity handled 4×8 sheets of composite decking with ease. I was worried the battery might die halfway through, but with a 6.0Ah FlexVolt battery, I cut all my boards in one go. The cuts were clean, and the fence stayed true, even after hours of use.
Crafting Custom Shelves
For a recent project, I built custom bookshelves for my living room. The saw’s precision was a lifesaver. I used it to cut plywood for the shelves and hardwood for the trim. The brushless motor powered through oak without bogging down, and the rack and pinion fence made it easy to get consistent cuts. I also appreciated the dust collection port, which kept my garage from turning into a sawdust storm.
Punchout and Trim Work
As a finish carpenter, I often do small punchout jobs, like trimming doors or cutting baseboards. The DeWalt 20V table saw is my go-to for these tasks. Its portability means I can bring it right to the job site, and the compact blade size is perfect for precision cuts. I’ve even used it to cut thin strips for molding, and the mini fence feature kept everything safe and accurate.
Comparing the DeWalt 20V Table Saw to Corded Alternatives
You might be wondering: how does this cordless saw stack up against a corded table saw? I’ve used both, so let’s break it down.
Corded table saws, like the DeWalt DWE7491RS, are more powerful and don’t rely on batteries. They’re great for heavy-duty jobs, like cutting thick hardwood all day. But they’re heavier (often 90 pounds or more) and require a power source, which isn’t always convenient. I once had to run a 50-foot extension cord across a job site, and it was a nightmare to manage.
The DeWalt 20V table saw, on the other hand, is all about portability and convenience. It’s not as powerful as a corded model, but it’s more than capable for most DIY and light professional tasks. The 8-1/4-inch blade is smaller than the 10-inch blades on most corded saws, which limits its cutting depth to 2-1/2 inches. For me, that’s enough for 90% of my projects, but if you’re cutting thicker timber, you might need a corded saw or a different tool, like a circular saw.
Battery life is another consideration. With a FlexVolt battery, the 20V table saw lasts long enough for most jobs, but heavy users will need spares. Corded saws don’t have this issue, but you’re tied to an outlet. For me, the trade-off is worth it for the freedom to work anywhere.
Tips for Getting the Most Out of Your DeWalt Cordless Table Saw
After using this saw for months, I’ve picked up a few tricks to maximize its performance. Here’s what I recommend:
- Invest in a Good Blade: The included 24-tooth blade is fine for general use, but for smoother cuts, I upgraded to a 40-tooth carbide-tipped blade. It’s perfect for finish work and plywood.
- Keep Spare Batteries: If you’re tackling a big project, have at least one extra FlexVolt battery. Swapping batteries takes seconds, and you won’t lose momentum.
- Use a Sacrificial Surface: When cutting on a table, place a piece of plywood or foam board underneath to avoid damaging your surface. I learned this the hard way after nicking my workbench!
- Clean the Dust Port Regularly: The dust collection system works well, but sawdust can build up. I clean it out after every big job to keep it efficient.
- Check Fence Alignment: Before starting, double-check that the fence is parallel to the blade. It’s usually spot-on, but a quick check saves headaches.

Who Should Buy the DeWalt Cordless Table Saw 20V?
This saw is perfect for DIYers, homeowners, and light-duty professionals who value portability and convenience. If you’re working on projects like decks, shelves, or trim work, it’s a fantastic choice. It’s also ideal for anyone working in remote locations without easy access to power, like off-grid cabins or outdoor job sites.
If you’re a professional framer or need to cut thick timber all day, you might want a corded saw for its extra power and unlimited runtime. But for most home improvement tasks, the DeWalt 20V table saw gets the job done without the hassle of cords.
Maintenance and Care for Longevity
To keep your saw in top shape, a little TLC goes a long way. I clean mine after every use, wiping down the table to remove sawdust and debris. The table coating reduces friction, but it can get gunked up if you don’t stay on top of it. I also check the blade for resin buildup and clean it with a blade cleaner if needed.
Store the saw in a dry place to prevent rust, especially if you’re in a humid area. I keep mine in a garage with a dehumidifier. If you’re not using it for a while, remove the battery to avoid any drain. Finally, inspect the fence and blade guard regularly to make sure they’re secure and functioning properly.
