Milwaukee 11 Amp 4-1/2" Small Angle Grinder Paddle, No-Lock

As someone who regularly works with power tools, particularly angle grinders, I was eager to test out the Milwaukee 11 Amp 4-1/2" Small Angle Grinder Paddle, No-Lock (Model 6147-31). With Milwaukee's reputation for durability and power, I had high expectations. This grinder did not disappoint, though it did come with a few quirks worth noting.

Power and Performance

The first thing that stands out about this grinder is its raw power. The 11 Amp motor delivers 11,000 RPM, which is more than sufficient for a variety of tasks, from cutting steel pipes to grinding down welds. I put it to the test on a 1 1/4" steel pipe and was impressed by how effortlessly it powered through without slowing down. The grinder maintained a consistent speed, even under heavy load, which speaks volumes about its robust motor.

Build Quality and Design

Milwaukee has a reputation for building sturdy tools, and this grinder is no exception. The overall build feels solid in hand, and the weight distribution is well-balanced. At 8.16 lbs, it’s not the lightest tool, but it’s manageable and feels durable. The metal casing adds to the tool's rugged feel, ensuring it can withstand tough job site conditions.

One feature I particularly appreciated is the advanced airflow system, designed to enhance motor life by keeping it cool. This, combined with the debris baffles, helps protect the internal components from dust and debris, which is crucial for a tool that often operates in dirty environments.

Ease of Use

The paddle switch is ergonomically designed, making it comfortable to use for extended periods. Unlike the slide switch found on some other models, the paddle switch is easier to control and reduces user fatigue. The safety lock-off switch is a nice touch, preventing accidental starts and adding an extra layer of safety.

The grinder also comes with a tool-free accessory change system. This feature is a significant time-saver, allowing you to switch between tasks quickly without needing additional tools. The adjustable guard is another convenient feature, though it does have some limitations. The detent system allows for quick adjustments, but the range of positions is somewhat limited compared to friction ring systems on other grinders. This can be a minor inconvenience if you need the guard at a very specific angle.

Durability and Reliability

During my testing, the grinder proved to be extremely durable. I used it for a variety of tasks, including stripping paint and cutting concrete blocks, and it showed no signs of slowing down. Even after prolonged use, the motor remained cool, thanks to the advanced airflow system. The grinder also handled the ingestion of grinding dust well, which can be a common issue with these tools.

However, it's worth noting that some users have reported issues with the guard breaking after light use. While I didn't encounter this problem myself, it's something to be aware of, especially if you plan to use the grinder heavily.

Accessories and Storage

The grinder comes with a durable carrying bag, which is a nice addition. The bag is spacious enough to hold the grinder, extra wheels, and a few other accessories. However, it's a tight fit if you try to store the grinder with a wheel or blade installed. This isn't a deal-breaker, but it does mean you’ll need to remove the accessories before packing it away.

Safety Features

Safety is a critical aspect of any power tool, and Milwaukee has included several features to ensure safe operation. The paddle switch with a lock-on mechanism provides better control and reduces the risk of accidental starts. The adjustable guard helps to minimize debris and sparks, which is particularly important when working with materials like metal and concrete.

Overall Impression

In summary, the Milwaukee 11 Amp 4-1/2" Small Angle Grinder is a powerful, durable, and user-friendly tool that excels in a variety of applications. Its robust motor, advanced airflow system, and tool-free accessory changes make it a versatile addition to any tool collection. While the guard's limited adjustment range and potential durability issues are minor drawbacks, they don't overshadow the grinder's overall performance and reliability.

Recommendation

I highly recommend this Milwaukee angle grinder for both professional tradespeople and serious DIY enthusiasts. Its combination of power, durability, and ease of use makes it a standout tool in its category. Whether you're cutting steel, grinding welds, or tackling other heavy-duty tasks, this grinder is more than capable of getting the job done efficiently and effectively. The 5-year warranty also provides added peace of mind, ensuring that Milwaukee stands behind the quality of their product.
