Today, we’re diving into the nitty-gritty world of DeWalt cordless grinders, specifically the DCM848 and DCM849.
Both of these bad boys are making waves in the realm of power tools, but the big question is, which one is better for your needs?
Here’s a comparison table summarizing the key differences between the DeWalt DCM848 and DCM849 cordless grinders:

| Availability of Accessories | DeWalt’s Wide Range of Compatible Accessories | DeWalt’s Wide Range of Compatible Accessories |
1. Motor Power: The Heart of the Grinder
The DCM848 comes equipped with a 20V MAX brushless motor, delivering 8500 RPM (Rotations Per Minute) of sheer grinding power. This motor is a workhorse, capable of tackling a variety of tasks, from cutting to grinding.
The DCM849, on the other hand, boasts a more potent 20V MAX XR brushless motor, and it kicks it up a notch with a whopping 9000 RPM. This extra juice can make a significant difference, especially when dealing with tougher materials or larger projects.
Example: Let’s say you’re cutting through metal pipe with both grinders. The DCM848 will do a fine job, but if you’ve got a lot of cuts to make, the DCM849’s extra RPM will get the job done faster and with less effort.
2. Paddle Switch vs. Slide Switch: The Ergonomic Battle
The DCM848 features a paddle switch, which is super convenient when you need to toggle the grinder on and off quickly. This design is also excellent for left-handed users since it’s ambidextrous.
The DCM849 sports a slide switch, which can be more suitable for extended use, as you can lock it in the “on” position. This reduces finger fatigue during prolonged grinding sessions.
Example: If you’re grinding down concrete countertops for a kitchen renovation, the DCM849’s slide switch might save your fingers from cramping up after hours of continuous work.
3. Kickback Brake: Safety First
The DCM848 doesn’t have a kickback brake, which means the grinding wheel may continue to spin after you release the switch. While it’s not a deal-breaker, it does require a little extra caution.
The DCM849, on the other hand, features a kickback brake that rapidly stops the wheel’s rotation when the switch is released. This is a game-changer for safety, preventing accidental slips and mishaps.
Example: When working with a delicate material like ceramic tiles, the DCM849’s kickback brake can save you from costly and frustrating mishaps.
4. Tool-Free Guard Adjustments: Convenience Matters
Both DCM848 and DCM849 grinders have tool-free guard adjustments, which makes it a breeze to reposition the guard to suit different cutting or grinding angles. This feature is an absolute time-saver and can significantly boost your efficiency.
Example: Imagine you’re trimming some steel rods at various angles for a custom metalwork project. The ability to adjust the guard without fumbling for tools ensures a smooth workflow with either grinder.
5. Battery Compatibility: Endurance Matters
Both the DCM848 and DCM849 grinders are part of DeWalt’s 20V MAX lineup, which means they share the same battery platform. If you’re already invested in the DeWalt ecosystem, you can use your existing 20V MAX batteries with these grinders. This compatibility can save you some cash, and it’s also eco-friendly, reducing the need for extra batteries.
Example: Suppose you already own a DeWalt 20V MAX drill, and you have a few spare batteries. Being able to use those batteries with either grinder is a major convenience.
6. Handle and Grip: Comfort is Key
Both grinders feature ergonomic handles and grips, designed for user comfort during extended use. However, some users might find the grip of one model more comfortable than the other. It’s a matter of personal preference, so if possible, get your hands on both grinders to see which one feels better for you.
Example: Imagine working on a project that requires a lot of overhead grinding. The grinder with the more comfortable grip will make the task less exhausting.
7. Price Point: Budget Considerations
Price often plays a significant role in the decision-making process. As of my last update in September 2021, the DCM849 is generally priced a bit higher due to its enhanced features. It’s essential to weigh the additional cost against the benefits it brings to your work.
Example: If you’re a DIYer with occasional projects, the DCM848 might fit your budget better. On the other hand, if your livelihood depends on the grinder’s performance, investing in the DCM849 could be a wise choice.
8. Portability and Weight: On-the-Go Versatility
Both grinders are cordless and relatively lightweight, making them suitable for various applications and locations. Consider the portability aspect if you frequently need to move your tools from one job site to another.
Example: Let’s say you’re working on a landscaping project that involves cutting through tree branches at different spots in your garden. The lighter weight of these grinders makes it easy to carry them around and get the job done efficiently.
9. Availability of Accessories: Expanding Capabilities
DeWalt offers a wide range of accessories and attachments for their grinders, from different types of grinding wheels to specialized guards. Check which accessories are readily available for the model you choose, as this can expand the capabilities of your grinder for various tasks.
Example: Suppose you’re a woodworker who occasionally dabbles in metalworking. Having access to compatible grinding wheels for both materials can be a game-changer for your workshop.
