Milwaukee 1-1/8" SDS Plus L-Shape Rotary Hammer

As someone who has spent countless hours working with various rotary hammers, I had high expectations when I picked up the Milwaukee 1-1/8" SDS Plus L-Shape Rotary Hammer (Model 5359-21). This tool promises a lot with its robust feature set and impressive specifications. After putting it through its paces, I have a comprehensive understanding of its strengths and weaknesses.

Design and Ergonomics

One of the first things you notice about this rotary hammer is its design. Milwaukee has clearly put considerable thought into making this tool user-friendly. Weighing in at just 7.5 pounds and featuring a balanced, L-shape design, the tool is easy to handle, even during extended use. The D-style rear handle provides a secure grip, which is crucial for maintaining control during high-intensity tasks. The two-finger speed control trigger is another thoughtful addition, allowing for precise hole positioning and better overall control.

Power and Performance

The Milwaukee rotary hammer boasts a 120V corded power source, delivering a no-load speed of 0-1,500 RPM and a blow energy of 3.6 ft-lbs. With a maximum of 5,500 blows per minute, it’s clear that this tool is designed for heavy-duty tasks. It has three operational modes: rotation only, hammer only, and rotation with hammering. This versatility makes it suitable for a wide range of applications, from drilling into wood and steel to breaking up concrete.

In my experience, the tool performed exceptionally well in all three modes. Drilling through masonry was a breeze, and the hammer-only mode made quick work of chipping away old mortar. The rotation with hammering mode was particularly effective for drilling anchor holes in concrete. The tool’s power-to-weight ratio is impressive, making it one of the most efficient rotary hammers I’ve used.

Durability and Build Quality

While the tool's performance is top-notch, there are some concerns regarding its durability. During extended use, the motor tends to overheat, which can be problematic in continuous, heavy-duty applications. Additionally, the motor area is not well-sealed, making it susceptible to damage from dust and debris. This is particularly concerning if you’re working in dirty or sandy environments. I encountered issues with sand getting inside the motor area, which led to damaged brushes and leaking grease.

Vibration and Comfort

Milwaukee has incorporated an effective anti-vibration system, which significantly reduces user fatigue. This feature is particularly beneficial when working on large projects that require prolonged use. The tool’s vibration reduction system allows for one-handed operation in certain scenarios, although it’s generally advisable to use both hands for better control and safety. The cushioned grip and adjustable side handle further enhance user comfort, making it possible to work for extended periods without undue strain.

Storage and Accessories

One area where the tool could use improvement is its storage case. While the case is sturdy and provides excellent protection for the tool, it lacks compartments for storing bits and other accessories. This oversight means you’ll need an additional bag or toolbox to keep your bits organized, which can be inconvenient.

Specific Use Cases

In practical applications, the Milwaukee rotary hammer excels in both light and medium-duty tasks. For instance, drilling holes in concrete for anchors was quick and efficient. The tool also performed well in demolition tasks, such as breaking up a cemented brick paver walkway. However, it’s worth noting that for more extensive demolition work, you might need a more powerful tool. The rotary hammer is well-suited for smaller jobs like drilling holes in concrete slabs, cement blocks, or boulders and breaking up small concrete slabs.

Issues and Drawbacks

Despite its many strengths, the tool is not without its flaws. Some users have reported issues with the chuck, finding it difficult to insert SDS plus bits. There have also been instances where the tool’s motor burned out after limited use, which raises concerns about its long-term reliability. Additionally, the guide rod tends to slip during use, which can affect drilling accuracy. Taping the rod or marking the drill bit itself can mitigate this issue, but it’s an inconvenience nonetheless.

Final Thoughts

Overall, the Milwaukee 1-1/8" SDS Plus L-Shape Rotary Hammer is a powerful, versatile tool that performs exceptionally well in a variety of applications. Its lightweight design, effective anti-vibration system, and user-friendly features make it a pleasure to use. However, its durability issues and lack of well-thought-out storage options are drawbacks that potential buyers should consider.

Recommendation

Would I recommend this tool? Yes, but with some reservations. If you’re looking for a rotary hammer that offers excellent power and versatility for light to medium-duty tasks, this Milwaukee model is a solid choice. Its ergonomic design and effective vibration reduction system make it comfortable to use for extended periods. However, if you’re planning to use it in dirty environments or for continuous, heavy-duty applications, you might want to consider other options due to its susceptibility to overheating and motor damage.

In conclusion, the Milwaukee 1-1/8" SDS Plus L-Shape Rotary Hammer is a robust and versatile tool that excels in many areas but has some limitations that potential buyers should be aware of. If you can work around these issues, it’s a valuable addition to any toolkit.
