Milwaukee 13 Amp 5" Small Angle Grinder Paddle, Lock-On

The Milwaukee 13 Amp 5" Small Angle Grinder, model 6117-30, is a robust and powerful tool designed with industrial use in mind. Having had the opportunity to work extensively with this grinder, I can confidently say that it delivers on power and performance, though it has its share of quirks.

First and foremost, the 13 Amp motor is an absolute powerhouse. With a no-load speed of 11,000 RPM, this grinder can handle heavy-duty tasks without bogging down. Whether I was cutting through thick steel or grinding down welds, the tool maintained its speed and power, thanks to Milwaukee's Constant Power Technology. This feature ensures the grinder doesn't lose momentum under load, which is crucial for maintaining consistent performance during demanding tasks.

One of the standout features of this grinder is the electronic clutch. This safety feature is designed to prevent bind-up and extend the tool's life. During my usage, I found that it effectively minimized the risk of sudden stops that could otherwise lead to accidents or tool damage. Additionally, the overload protection is a welcome addition, ensuring the motor's longevity by preventing overheating during extended use.

The tool-free accessory change is another highlight. Swapping out discs and accessories without the need for additional tools saves time and effort, making the workflow smoother. The adjustable guard can also be installed and adjusted without tools, which is a significant convenience. However, the guard's spring-loaded lever and tooth system can be a bit restrictive, as it only allows positioning in certain places. While this didn't pose a major issue for me, it might be a minor inconvenience for those who prefer more flexibility in guard positioning.

Comfort during use is always a concern with power tools, especially for extended periods. The anti-vibration side handle on this grinder does a commendable job of reducing hand fatigue. However, the tool's overall form factor is somewhat bulky. Even with XL gloves, I found it challenging to maintain a comfortable grip at times. The paddle switch lock-on mechanism, while useful for continuous operation, can be a bit tricky and potentially dangerous if not handled with care. It's essential to be mindful of this feature to avoid accidental activation or prolonged running when not intended.

Durability is where this grinder truly shines. The double-insulated construction and sturdy build quality give it a rugged feel, capable of withstanding the rigors of industrial use. I've dropped it a few times from moderate heights, and it held up without any significant damage. The soft start feature is another thoughtful addition, providing better control during startup and reducing the initial jolt that can sometimes catch users off guard.

Despite its strengths, the grinder isn't without its drawbacks. The tool's weight, at around 7 pounds, can become cumbersome during prolonged use, especially for tasks requiring precision. Additionally, the handle design, while effective in reducing vibration, could benefit from a more ergonomic shape to enhance user comfort further.

One aspect that left me somewhat disappointed was the lack of a carrying case. Given the tool's industrial-grade build and the rough environments it's likely to be used in, a case would have been a practical addition for storage and transport. It's a minor gripe, but one that could improve the overall user experience.

In terms of reliability, my experience has been mostly positive. However, I did encounter a few hiccups. On one occasion, the grinder's gearbox became excessively hot after extended use, raising concerns about its long-term durability. While this didn't lead to immediate failure, it's something to keep an eye on, especially for those who plan to use the tool intensively.

In conclusion, the Milwaukee 13 Amp 5" Small Angle Grinder is a formidable tool that excels in power and durability. Its robust motor, electronic clutch, and overload protection make it suitable for heavy-duty industrial tasks. The tool-free accessory change and adjustable guard add to its convenience, while the anti-vibration handle enhances comfort during use.

However, the grinder's bulkiness and somewhat tricky paddle switch mechanism may pose challenges for some users. The lack of a carrying case is a minor oversight, and the potential for the gearbox to overheat warrants caution during prolonged use.

Would I recommend this grinder? Yes, but with reservations. If you're in need of a powerful, reliable tool for industrial applications and can manage its bulk and occasional quirks, the Milwaukee 13 Amp 5" Small Angle Grinder is a solid choice. Its performance and durability make it a valuable addition to any professional's toolkit. However, if ergonomics and ease of use are your primary concerns, you might want to explore other options before making a decision.
