DeWalt Slide Switch Small Angle Grinder Review
The DeWalt DCG405B Slide Switch Small Angle Grinder is a robust addition to any tool kit, particularly for those who value the convenience and portability of cordless tools. Having used this grinder extensively in various scenarios, from construction projects to everyday household tasks, I can confidently say it stands out in several key areas.
Build Quality and Design
First and foremost, the build quality of this grinder is exceptional. DeWalt has a reputation for producing durable tools, and this model is no exception. The grinder feels solid in hand, with a weight that suggests both durability and reliability. It's heavier than some might expect, but this added heft contributes to its stability during use. The brushless motor is a significant advantage, reducing the need for maintenance and ensuring a longer lifespan for the tool.
The slide switch design is another highlight. While it may take some getting used to, it offers a level of control that is particularly useful for extended grinding sessions. The switch is designed to prevent accidental startups, which is a crucial safety feature, especially in a busy work environment. Additionally, the Kickback Brake and Power Loss Reset® features are excellent safety measures that provide peace of mind during operation.
Performance
In terms of performance, the DeWalt DCG405B does not disappoint. The grinder boasts plenty of torque and RPM, making it suitable for a wide range of tasks. Whether you're cutting through metal, sharpening mower blades, or even tackling concrete, this grinder handles it all with ease. The high-speed brushless motor ensures efficient operation, and the low vibration is a pleasant surprise, reducing user fatigue during prolonged use.
One of the standout features is the Kickback Brake, which engages during pinch, stall, or bind-up events. This safety mechanism quickly stops the wheel and shuts off the grinder, preventing potential accidents. The brake stops the wheel in two seconds or less on average, which is impressive and adds an extra layer of safety.
Battery Life and Power
As with many cordless tools, battery life is a critical consideration. The DeWalt DCG405B is no different. The grinder is a power-hungry tool, and it can run through batteries quickly, especially during heavy-duty tasks. I found that using a 5 AH battery significantly improves the runtime, allowing for more extended periods of use without frequent recharges. However, it's advisable to have multiple batteries on hand if you're planning to use the grinder for extended projects.
The lack of an included battery and charger at this price point is a downside. For a tool in this price range, one would expect at least a starter battery to be included. This omission can be a deal-breaker for some, especially those new to the DeWalt 20V Max system who don't already have compatible batteries.
Ease of Use
Setting up and using the DeWalt DCG405B is straightforward. The grinder is easy to assemble right out of the box, and the handle can be screwed in without any hassle. The tool-less wheel change feature is a significant advantage, allowing for quick and easy disc changes without needing a spanner wrench. However, it would have been nice to have a dedicated spot on the tool to store the wrench for those who prefer using one.
The adjustable guard is another user-friendly feature, allowing for quick adjustments to the guard position without needing additional tools. This makes it easier to adapt the grinder to different tasks and ensures better safety during operation.
Versatility
One of the major selling points of the DeWalt DCG405B is its versatility. This grinder is suitable for a wide range of applications, from cutting and grinding to sanding and polishing. The ability to use it anywhere without being tethered to a power outlet is a significant advantage, particularly for those who work in remote locations or on job sites without easy access to electricity.
The grinder's performance is comparable to corded models, which is impressive for a cordless tool. The convenience of not having to deal with extension cords cannot be overstated, making this grinder an excellent choice for both professional contractors and DIY enthusiasts.
Final Thoughts
Overall, the DeWalt DCG405B Slide Switch Small Angle Grinder is a well-made, powerful, and versatile tool that performs admirably in various applications. Its robust build quality, safety features, and ease of use make it a valuable addition to any tool collection. However, the high power consumption and the lack of an included battery and charger are notable drawbacks.
Despite these minor issues, I would highly recommend the DeWalt DCG405B to anyone in need of a reliable and efficient cordless angle grinder. Its performance and convenience outweigh the drawbacks, making it a worthwhile investment for both professionals and serious DIYers. If you already own other tools in the DeWalt 20V Max lineup, this grinder is a no-brainer addition that will enhance your toolset's versatility and capability.
