Milwaukee 13 Amp 5" Small Angle Grinder Slide Lock-On

When I first got my hands on the Milwaukee 13 Amp 5" Angle Grinder, I was immediately struck by its solid build and heft. This is not a lightweight, and its robust construction speaks to its intended industrial use. The grinder is equipped with a powerful 13 Amp motor, which, on paper, promises to handle a variety of tough tasks with ease.

One of the standout features of this grinder is its variable speed control, allowing for a range of applications from grinding to cutting, and even more delicate work with wire brushes. The dial speed control is intuitive and provides a good level of precision, which is particularly useful when working in tight or intricate areas. The overload protection feature is another significant plus, as it helps to extend the motor life by preventing overheating and overloading.

However, it didn’t take long to notice a few quirks. The aluminum housing tends to get quite hot after a few minutes of continuous use, especially when working with metal. This can make it uncomfortable to hold for extended periods and raises some concerns about long-term durability. While the advanced airflow system is designed to reduce debris ingress, it doesn’t seem to mitigate the heat issue effectively.

The tool-free accessory change is a convenient feature, making it easy to switch between different discs and attachments without the need for additional tools. The disc hold-down nut is particularly well-designed, with a generous knurled edge that makes it easy to grip and secure the disc tightly. This is a small but thoughtful detail that enhances the overall user experience.

Comfort is another area where Milwaukee has put in some effort. The anti-vibration side handle significantly reduces the strain on your hands and arms during prolonged use. However, I did find the handle positions somewhat limiting. The top handle hole has been eliminated on this model, which can make certain grinding and cutting positions less comfortable. For horizontal work, the side handles are adequate, but for vertical or awkward angles, the lack of a top handle option is noticeable.

The electronic clutch is a feature I found particularly useful. It prevents the grinder from binding up, which can be a common issue when working with tougher materials. This not only improves safety but also helps to maintain a consistent performance, reducing the risk of sudden stops or kickbacks.

In terms of performance, this grinder does not disappoint. It has a no-load speed of 11,000 RPM, which, combined with the 13 Amp motor, provides more than enough power for most industrial tasks. I used it to cut through 3/16" and 1/4" wall tubing and some 3" x 3" angle iron without any issues. The grinder sliced through the metal effortlessly, and the lower RPMs with higher torque made the process smooth and efficient.

Noise level is another factor to consider with any power tool, and this grinder is relatively quiet compared to others I’ve used. It’s not silent by any means, but the noise is manageable and doesn’t require heavy-duty ear protection for short durations.

Durability is always a concern with power tools, especially those used in industrial settings. The Milwaukee grinder feels sturdy and well-built, and the 5-year warranty provides some peace of mind. However, the heating issue around the aluminum housing does raise some questions about its long-term reliability. It’s also worth noting that customer service experiences can vary, and it's important to ensure you have a reliable point of contact should any issues arise.

Overall, the Milwaukee 13 Amp 5" Angle Grinder is a powerful and versatile tool that performs well in a variety of applications. Its robust construction, combined with features like variable speed control, overload protection, and an electronic clutch, make it a solid choice for industrial use. The tool-free accessory change and anti-vibration handle are thoughtful additions that enhance user comfort and convenience.

However, the heating issue and the limited handle positions are notable drawbacks. If you’re planning to use this grinder for extended periods or in demanding conditions, these factors could be a significant downside.

Would I recommend this tool? If you need a powerful, versatile grinder for industrial applications and can manage the heating issue, then yes, this Milwaukee grinder is a solid choice. Its performance and features outweigh its minor flaws, making it a valuable addition to any workshop. However, if comfort and prolonged use are top priorities, you might want to consider other options or ensure you have appropriate safety measures in place to manage the heat.
