Hey there, fellow woodworker! If you’re reading this, chances are you’re a proud owner of a DeWalt miter saw, or maybe you’re thinking about fixing one up. I’ve spent countless hours in my workshop, cutting precise angles and crafting projects with my trusty DeWalt miter saw, and let me tell you—it’s a game-changer. But like any hardworking tool, it needs a little TLC from time to time. That’s where DeWalt miter saw replacement parts come in.
Whether it’s a worn-out blade, a faulty motor brush, or a cracked kerf plate, finding the right parts can keep your saw running like new. In this guide, I’m going to walk you through everything I’ve learned about sourcing and installing replacement parts for DeWalt miter saws. Let’s dive in and make sure your saw stays in top shape!
Why DeWalt Miter Saws Are Worth Maintaining
I’ve been using DeWalt miter saws for years, and I can’t sing their praises enough. They’re built tough, cut with precision, and handle everything from delicate trim work to heavy-duty framing. But even the best tools take a beating over time. Sawdust gets everywhere, blades dull, and parts wear out. That’s not a reason to toss your saw, though! Replacing parts is often cheaper than buying a new one, and it’s a great way to keep your favorite tool performing at its best.
Maintaining your DeWalt miter saw also saves you money in the long run. A single replacement part, like a $10 carbon brush, can fix a motor that’s acting up, saving you from dropping hundreds on a new saw. Plus, keeping your saw in good condition ensures your cuts stay clean and accurate, which is critical for any woodworking project. I’ve learned that a little maintenance goes a long way, and with the right parts, your DeWalt can last for decades.
Common DeWalt Miter Saw Parts That Need Replacing
Over the years, I’ve replaced a handful of parts on my DeWalt miter saws. Some wear out faster than others, depending on how often you use the tool and what materials you’re cutting. Here’s a rundown of the most common parts that might need replacing:
Blade
The blade is the heart of your miter saw. It’s what does the actual cutting, so it’s no surprise it wears out. Dull blades tear wood instead of slicing it cleanly, and that’s when I know it’s time for a new one. Most DeWalt miter saws use 10-inch or 12-inch blades with a 5/8-inch or 1-inch arbor hole. I always keep a spare blade on hand—usually a high-quality carbide-tipped one for smoother cuts.
Kerf Plate
The kerf plate is that plastic piece on the saw’s base where the blade cuts through. It helps reduce splintering and keeps your cuts clean. After years of use, mine started to crack, and I noticed my cuts weren’t as precise. Replacing the kerf plate is an easy fix, and it’s usually held in place with a few screws. Just make sure you get the right one for your model.
Carbon Brushes
Carbon brushes are small but mighty. They conduct electricity to the motor, and they wear down over time. When my saw started running sluggishly or shutting off randomly, I checked the brushes first. They’re cheap to replace—usually under $20 for a pair—and it’s a quick job. I always inspect the motor’s armature while I’m at it to catch any bigger issues.
Blade Guard
The blade guard keeps you safe by covering the blade when it’s not in use. I’ve had a guard get bent after an accidental drop, and it wouldn’t retract smoothly anymore. A replacement guard is easy to install and ensures you’re not compromising on safety.
Fence
The fence is what keeps your workpiece steady for accurate cuts. If it gets bent or damaged, your cuts can go off-kilter. I’ve replaced a fence on my DeWalt DWS780 after a particularly rough job, and it made a huge difference in my cut quality.
Here’s a quick table summarizing these parts, their purpose, and why they might need replacing:
| Part | Purpose | Why Replace? |
|---|---|---|
| Blade | Cuts through wood and other materials | Dull or damaged blades cause rough, inaccurate cuts |
| Kerf Plate | Reduces splintering and supports clean cuts | Cracks or wears out, leading to poor cut quality |
| Carbon Brushes | Conducts electricity to the motor | Wears down, causing motor issues or power loss |
| Blade Guard | Protects user by covering the blade when not in use | Damage or sticking prevents safe operation |
| Fence | Keeps workpiece aligned for accurate cuts | Bending or damage affects cut precision |
How to Identify the Right Replacement Parts
Finding the right parts for your DeWalt miter saw can feel overwhelming, especially with so many models out there—like the DW703, DW708, DWS779, or DWS780. I’ve made the mistake of ordering the wrong part before, and let me tell you, it’s frustrating. Here’s how I make sure I get it right every time:
First, check your saw’s model number and type. You’ll usually find this on a sticker on the saw’s body. The “type” is important because DeWalt often releases different versions of the same model with slight variations. For example, a DW704 Type 3 is different from a DW704 Type 5.
Next, use the part number or description to search for replacements. DeWalt’s official parts website, ServiceNet, is my go-to. You can enter your model number and pull up a detailed parts diagram. If you’re not sure what part you need, these diagrams are a lifesaver—they show every component of your saw.
If you’re replacing something like a blade, double-check the size and arbor hole. A 10-inch blade won’t fit a 12-inch saw, and a 5/8-inch arbor won’t work with a 1-inch bore. I learned this the hard way when I ordered a blade that didn’t fit my DWS716.
Finally, stick to genuine DeWalt parts whenever possible. Aftermarket parts can be tempting because they’re cheaper, but I’ve found they don’t always fit perfectly or last as long. For critical components like brushes or kerf plates, I always go with OEM (original equipment manufacturer) parts for peace of mind.
Where to Buy DeWalt Miter Saw Replacement Parts
When I need parts, I’ve got a few favorite places to shop. Each has its pros and cons, so here’s what I’ve learned:
DeWalt’s ServiceNet
ServiceNet is DeWalt’s official parts portal. I love it because it’s reliable, and you can trust you’re getting genuine parts. You just enter your model number, and it pulls up a list of parts specific to your saw. The downside? It’s only available for U.S. customers, and shipping can take a week or two.
Online Retailers
Sites like eReplacementParts, Fix.com, and Power Tool Replacement Parts are great for fast shipping and competitive prices. I’ve used eReplacementParts for hard-to-find parts for older models like the DW705. They also have helpful customer service if you’re unsure about a part.
eBay and Specialty Sellers
If you’re working on a discontinued model, eBay can be a goldmine. I’ve found parts for my old DW708 on there when nowhere else had them. Just be careful to verify the seller’s reputation and ensure the part matches your model. Some sellers specialize in obsolete DeWalt parts, which is a lifesaver for older saws.
Local DeWalt Service Centers
If you prefer shopping in person, DeWalt has authorized service centers across the U.S. I’ve visited one near me to pick up a kerf plate, and they had it in stock. You can find a service center on DeWalt’s website by entering your zip code.
Pro tip: Always compare prices across a few sites. I’ve seen the same carbon brush sell for $8 on one site and $15 on another. A little research can save you some cash.
How to Replace Common DeWalt Miter Saw Parts
Replacing parts might sound intimidating, but most repairs are straightforward if you have the right tools and a bit of patience. Here’s how I’ve tackled some common replacements:
Replacing the Blade
Changing a blade is something I do regularly. First, unplug the saw for safety. Then, lock the blade in place using the spindle lock (usually a button near the blade). Use a wrench to loosen the blade bolt—turn it clockwise, as it’s often reverse-threaded. Swap out the old blade for the new one, making sure the teeth face downward. Tighten the bolt, and you’re good to go. The whole process takes about 10 minutes.
Installing a New Kerf Plate
A cracked kerf plate is an easy fix. Unscrew the old plate from the saw’s base—there are usually three screws on each side. Line up the new plate, screw it in, and make a test cut to ensure it’s aligned.应用

Replacing Carbon Brushes
When my saw’s motor started acting up, I checked the carbon brushes. Unplug the saw, then locate the brush caps (usually on the motor housing). Use a screwdriver to remove them, pull out the old brushes, and pop in the new ones. Check the armature for wear while you’re in there. It’s a 15-minute job that can save your motor.
Tips for Maintaining Your DeWalt Miter Saw
I’ve learned that preventing issues is just as important as fixing them. Here are some tips I follow to keep my saw in top shape:
- Clean Regularly: Sawdust builds up fast. I use compressed air to blow out dust from the motor and blade area after every big project.
- Check Alignment: A misaligned fence or blade can ruin your cuts. I check my saw’s alignment every few months using a square.
- Lubricate Moving Parts: A drop of machine oil on the pivot points keeps everything moving smoothly.
- Store Properly: I keep my saw covered in my workshop to protect it from dust and moisture.
Conclusion
Your DeWalt miter saw is a workhorse, and with the right replacement parts, it can keep delivering precise cuts for years to come. I’ve been through the process of tracking down parts, making repairs, and maintaining my saws, and it’s always worth the effort. Whether it’s a new blade for cleaner cuts or a fresh set of carbon brushes to keep the motor humming, taking care of your saw is an investment in your craft. So, next time your DeWalt starts acting up, don’t sweat it—just grab the right part, roll up your sleeves, and get back to creating something amazing in your workshop.
