Milwaukee 13 Amp 5" Small Angle Grinder

As a seasoned tool enthusiast, I recently had the opportunity to test out Milwaukee's 13 Amp 5" Small Angle Grinder, model 6117-33. This grinder promises industrial-grade performance, and I was excited to see if it lived up to the brand's reputation for quality and durability.

Design and Build Quality

First impressions matter, and the 13 Amp grinder certainly makes a strong one. The robust construction is immediately noticeable, with an aluminum housing that feels sturdy and well-built. However, this solid build comes with a downside: the tool is quite heavy for its size. While the heft adds to its durability and stability during use, it might be a bit much for prolonged tasks.

The grinder features an 8-foot cord, which provides ample length for maneuvering around a workspace. The cord itself is thick and feels durable, a small but significant detail that adds to the overall quality impression. The tool-free accessory change system is a godsend, making it easy to switch between different discs and attachments without fumbling for additional tools.

Performance and Power

The 13 Amp motor, capable of reaching 11,000 RPM, is the heart of this grinder, and it doesn't disappoint. Whether I was cutting through 3/16" steel or grinding down welds, the grinder handled everything with ease. The Constant Power Technology ensures that the motor maintains its speed under load, which is crucial for consistent performance.

One standout feature is the electronic clutch, designed to prevent tool bind-up. This is particularly useful when working with tougher materials, as it helps to avoid sudden stops that could damage the tool or the workpiece. The anti-vibration side handle is another thoughtful addition, providing a more comfortable grip during extended use.

Heat Management

One of the more concerning aspects of this grinder is its tendency to get hot during use. After just a few minutes of continuous grinding, the aluminum housing became noticeably warm. While some heat build-up is expected with any high-power tool, the level of heat generated by this grinder was significant enough to make it uncomfortable to hold for extended periods. This could be a deal-breaker for those intending to use the grinder for long stretches at a time.

Usability and Comfort

Despite its weight, the grinder is reasonably comfortable to use, thanks in part to the anti-vibration handle. The soft start feature is also a nice touch, providing better control when powering up the tool. However, I did find the guard a bit cumbersome to adjust. It offers a limited number of useful positions, which can be frustrating when trying to find the perfect angle for a particular task.

The adjustable guard is a mixed bag. While it provides some flexibility, I found it somewhat restrictive in terms of positioning. This might not be a major issue for everyone, but it’s something to consider depending on your specific needs.

Durability and Reliability

Durability is where this grinder truly shines. The overload protection feature is a noteworthy inclusion, designed to extend the motor's life by preventing overheating. The overall build quality suggests that this tool can withstand the rigors of a demanding work environment. However, the heat issue could potentially impact its long-term reliability if not managed properly.

Customer Experience

It's worth mentioning the customer service experience, which can be a critical factor when investing in any tool. While I haven't personally had to deal with Milwaukee's customer service for this grinder, I have heard mixed reviews. Some users have had less than satisfactory experiences, which is something to keep in mind if you're considering this purchase.

Final Thoughts

The Milwaukee 13 Amp 5" Small Angle Grinder is a powerful and robust tool that excels in performance and durability. Its high-power motor and thoughtful features like the electronic clutch and anti-vibration handle make it a strong contender for both professional and serious DIY users. However, the significant heat build-up and somewhat cumbersome guard adjustment are notable drawbacks.

Would I recommend this grinder? Yes, but with reservations. If you need a high-power grinder for heavy-duty tasks and can manage the heat issue, this tool is a solid choice. Its durability and performance make it a valuable addition to any workshop. However, if you require a grinder for extended, continuous use, you might want to consider other options or be prepared to take frequent breaks to let the tool cool down.

In summary, the Milwaukee 13 Amp 5" Small Angle Grinder is a powerhouse with a few quirks. Its strengths in power and durability make it a worthwhile investment, provided you can work around its heat management issues.
