Milwaukee M12 FUEL 5/8" SDS Plus Rotary Hammer

The M12 FUEL 5/8" SDS Plus Rotary Hammer from Milwaukee has been a game-changer in my toolkit. As someone who frequently works in environments where portability and power are equally crucial, this compact rotary hammer drill has proven itself to be an invaluable asset.

Design and Build Quality

Right out of the box, the first thing that struck me was its compact and lightweight design. Weighing just 3.9 pounds and measuring 10 inches in length, this tool is incredibly easy to maneuver, especially in tight spaces. The build quality is robust, featuring Milwaukee’s signature durable plastic housing that feels solid but doesn’t add unnecessary weight. However, I did notice that the plastic housing doesn't seem as heavy-duty as some of Milwaukee’s other tools, which might be a minor concern for those who are particularly rough with their equipment.

Performance

The M12 Rotary Hammer is powered by a 12-volt motor that delivers a no-load speed of up to 900 RPM and 6,200 BPM. The electropneumatic mechanism ensures efficient drilling through concrete and masonry, making it more than capable of handling tasks that would usually require a bulkier and more powerful tool. I’ve used it to drill numerous 1/4" and 3/8" holes in concrete and brick, and it performed admirably every time. The variable speed setting allowed for precise control, which is particularly useful when starting a hole and needing to avoid bit wandering.

Battery Life and Efficiency

One of the standout features is the REDLITHIUM Battery Technology. I consistently achieved about 10-12 holes on a 6.0Ah battery, which is impressive for a 12V tool. The batteries are lightweight, making it easy to carry multiple spares without feeling bogged down. However, it's worth noting that the tool does consume batteries relatively quickly, especially when drilling larger or deeper holes. Having a few spare batteries on hand is almost a necessity for extended use.

Usability

The tool’s lightweight and well-balanced design make it easy to use one-handed, which is a significant advantage when working on ladders or in awkward positions. The ergonomic grip adds to the comfort, allowing for extended use without causing hand fatigue. The integrated LED light is a thoughtful addition, providing ample illumination in dimly lit areas, which is often the case in construction and renovation projects.

The two-mode operation—rotary hammer and rotation only—adds a layer of versatility, though I found myself wishing for a non-rotating hammer mode for chiseling tasks. This is a minor drawback but worth mentioning for those who might need that functionality.

Durability

In terms of durability, the M12 Rotary Hammer has held up exceptionally well. It has endured drops from ladders and rough handling without any significant issues. The tool's internal REDLINK Intelligence system provides overload protection, ensuring that it doesn’t overheat or suffer from excessive wear and tear.

Applications

This rotary hammer is ideal for a range of applications, from setting small anchors in concrete to drilling holes for electrical conduits. Its compact size makes it perfect for jobs that require mobility, such as working on scaffolding or in confined spaces. While it may not replace a more powerful SDS drill for heavy-duty tasks, it excels in its niche—light to medium-duty drilling tasks where portability and ease of use are paramount.

Pros and Cons

Pros:
- Lightweight and Compact: Easy to carry and use in tight spaces.
- Efficient Battery Life: REDLITHIUM batteries provide good runtime.
- Versatile: Two-mode operation for different drilling needs.
- Durable: Can withstand rough handling and drops.
- User-Friendly: Ergonomic design and LED light enhance usability.

Cons:
- Battery Consumption: Drains batteries relatively quickly, especially on tougher tasks.
- Limited Modes: Lacks a non-rotating hammer mode for chiseling.
- Plastic Housing: Could be more heavy-duty.

Final Thoughts

The M12 Rotary Hammer is a well-rounded tool that offers a perfect blend of power, portability, and efficiency. It's particularly well-suited for professionals who need a reliable, lightweight tool for drilling tasks in concrete and masonry. While it may not replace a full-sized SDS drill for heavy-duty applications, it excels in scenarios where maneuverability and ease of use are more critical.

Would I recommend the M12 Rotary Hammer? Absolutely. Its performance, coupled with its compact and lightweight design, makes it a valuable addition to any toolkit. Whether you’re an electrician, a plumber, or a DIY enthusiast, this tool offers the versatility and reliability you need to get the job done efficiently. The minor drawbacks are easily outweighed by its numerous advantages, making it a tool well worth considering for anyone looking to enhance their drilling capabilities.
