Milwaukee Cordless Lithium-Ion 4-1/2" Cut-off / Grinder Kit

When you think about tackling various cutting and grinding applications without being tethered by a cord, Milwaukee’s Cordless Lithium-Ion 4-1/2" Cut-off/Grinder Kit (Model 2680-22) stands out as an appealing option. With the freedom of cordless operation, this tool promises to enhance the versatility and efficiency of your work.

The first thing you notice about this grinder is its robust design. The 4-pole motor is a standout feature, providing ample power for a range of tasks. Whether you’re cutting through metal or grinding down surfaces, the motor’s performance is consistent and reliable. The tool spins at an impressive 10,000 RPM, which is comparable to many corded models, making it a formidable contender in the cordless category.

One of the aspects that really enhances user experience is the paddle switch. As someone who prioritizes safety and ease of use, I find the paddle switch to be a significant advantage. It’s easy to engage and disengage, providing better control over the tool. Moreover, the switch type is a personal preference for many, and I appreciate Milwaukee’s choice here.

The grinder’s design also includes L-shape intake vents that minimize debris entry. This is a critical feature, especially for those who work in environments where dust and debris are prevalent. It extends the life of the tool by preventing internal damage from foreign particles. Additionally, the tool-free guard allows for quick adjustments. This is a practical feature, particularly when switching between different tasks that require different guard positions.

Another notable feature is the 3-position side handle. This element adds to the tool’s versatility, offering better control and comfort during use. Whether you’re working at awkward angles or need extra stability, the adjustable handle positions make a noticeable difference. It’s these thoughtful design choices that contribute to the overall user-friendly nature of the grinder.

In terms of power source, the grinder is powered by an 18V Lithium-Ion battery. The kit includes two batteries and a charger, which is a great value addition. The batteries have a decent runtime, and the charger brings them back to full power in about an hour. This ensures that you can keep working with minimal interruptions. However, for more extended tasks, you might find yourself swapping batteries frequently. The batteries also feature fuel gauges, so you always know how much charge is left, preventing unexpected downtime.

One of the aspects that I find particularly impressive is the grinder’s balance and weight distribution. Weighing in at just under 6 pounds with the grinding wheel, battery, and side handle, it’s comparable to corded models in terms of heft. This balance means that the tool is comfortable to use for extended periods without causing undue fatigue.

However, there are a few areas where the grinder could see some improvements. For instance, it lacks a motor brake, which means you have to wait a few seconds for the wheel to stop spinning after releasing the paddle switch. This is a minor inconvenience but worth noting, especially when you’re accustomed to tools that stop immediately.

Another point of consideration is the storage case. The kit comes with a fabric case, which might not offer the best protection for the tool in rugged environments. A hard case would provide better durability and protection, especially if the tool is transported frequently.

Despite these minor drawbacks, the grinder’s performance and build quality are commendable. The burst-resistant guard provides excellent protection from flying debris and sparks, and the tool’s overall construction feels solid and durable. It’s clear that Milwaukee has put thought into crafting a tool that can withstand the demands of both professional and DIY users.

In practical applications, this grinder excels. Whether you’re manufacturing and welding steel pipes, cutting through metal cabinets, or performing quick home repairs, it delivers consistent and reliable performance. The freedom from cords is a significant advantage, allowing you to move around more freely and work in locations without easy access to power outlets.

For heavy-duty tasks, such as industrial work or extended grinding sessions, a corded grinder might still be the better choice. The cordless model, while powerful, can’t quite match the continuous power supply of a corded tool, and swapping batteries can interrupt workflow. However, for many other tasks, the convenience of a cordless grinder makes it a valuable addition to any toolkit.

In conclusion, I would highly recommend Milwaukee’s Cordless Lithium-Ion 4-1/2" Cut-off/Grinder Kit. It combines power, versatility, and user-friendly features in a well-balanced package. The freedom from cords is a significant benefit, and the tool’s performance is on par with many corded models. While it could benefit from a few enhancements, such as a motor brake and a more durable storage case, these are minor issues in an otherwise excellent tool. Whether you’re a professional tradesperson or a DIY enthusiast, this grinder is a robust and reliable choice that can handle a wide range of tasks with ease.
