DeWalt 60V MAX 4-1/2 in. - 6 in. Grinder with Kickback Brake Kit Review

4.6 out of 5

The DeWalt 60V MAX 4-1/2" - 6" Grinder Kit is a powerful addition to any toolkit, offering the convenience of a cordless design without compromising on performance. Having had the opportunity to put this grinder through its paces, I can confidently say it stands out for several reasons, both good and bad.

One of the first things you notice about this grinder is its impressive power. The 13 Amp equivalent motor performance truly lives up to its billing, providing a level of power that rivals many corded grinders. This is particularly evident in heavy-duty applications, such as cutting through thick metal or grinding down concrete. The motor's 9,000 RPM speed ensures that the grinder can handle a variety of tasks with ease, making it a versatile tool for both professional contractors and serious DIY enthusiasts.

The grinder's brake and safety features deserve special mention. The brake engages immediately upon trigger release, stopping the wheel within 1.5 seconds. This is a critical safety feature, especially when working in environments where quick stopping can prevent accidents. Additionally, the Kickback Brake and E-CLUTCH® system provide extra layers of safety by stopping the wheel in pinch or stall situations. These features not only enhance safety but also add to the tool's overall reliability.

In terms of usability, the grinder is designed with several thoughtful features. The ability to switch between 4-1/2" and 6" wheels without much hassle makes it adaptable to various tasks. The guards are easy to adjust and provide adequate protection, and the tool-free wheel change system is a significant time-saver. The handle can be positioned in multiple ways, allowing for ergonomic use in different applications.

However, the grinder is not without its drawbacks. One of the most commonly cited issues is the battery life. Even when using the recommended 60V 6Ah batteries, the runtime can be disappointingly short, especially under heavy use. On average, a fully charged battery lasts around 5 to 10 minutes of continuous grinding. This necessitates frequent battery changes and can be a significant inconvenience on larger jobs. Moreover, the batteries take a considerable amount of time to charge, which can disrupt workflow.

Another point of contention is the weight of the tool. While the grinder's robust build is a testament to its durability, it does make the tool quite heavy, especially when working overhead or in awkward positions. This can lead to user fatigue over extended periods, making it less ideal for prolonged use.

The grinder is also somewhat limited by its reliance on the 60V Flexvolt battery system. While these batteries are powerful, they are not compatible with the more common 20V DeWalt batteries that many users might already have. This means an additional investment in Flexvolt batteries and chargers, which can be quite costly. This lack of compatibility could be a dealbreaker for those who have already invested heavily in the 20V system.

Despite these drawbacks, the grinder has several redeeming qualities that make it an excellent tool for specific applications. Its power and versatility are unmatched in the cordless category, and the safety features provide peace of mind during use. The build quality is excellent, and the tool feels sturdy and well-made. For those who need a reliable, high-performance grinder for short bursts of heavy-duty work, this tool is hard to beat.

On the customer service front, my experience was mixed. While the initial support was helpful in addressing my concerns about battery life, the process of getting a replacement battery was cumbersome. This is something DeWalt could improve upon to enhance the overall user experience.

In conclusion, would I recommend the DeWalt 60V MAX 4-1/2" - 6" Grinder? Yes, but with reservations. If you're in need of a powerful, cordless grinder for occasional heavy-duty tasks, this tool is a fantastic choice. Its safety features, power, and build quality make it a reliable addition to any toolkit. However, if you require a grinder for continuous, extended use, the limitations in battery life and the tool's weight might be significant drawbacks. Additionally, the need for Flexvolt batteries adds an extra layer of expense that potential buyers should consider. Overall, it's a powerful tool with specific strengths and some notable weaknesses that users should weigh before making a purchase.
