Milwaukee Cordless Rotary Hammer

Switching to a cordless rotary hammer has been a game-changer for me, particularly the Milwaukee 2715-20. This tool, powered by an 18V lithium-ion battery, offers a blend of convenience and power that truly stands out on demanding job sites. Let me break down my experience with this tool and why it has become an essential part of my toolkit.

Power and Versatility

The first thing that struck me was the power. With a brushless motor generating 3.3 ft-lb of impact energy, this rotary hammer cuts through concrete and masonry with remarkable ease. The no-load speed ranges from 0 to 1,350 RPM, and it can deliver up to 5,000 blows per minute (BPM). This range of power settings makes it versatile enough to handle a variety of tasks, from drilling into softer materials to heavy-duty demolition work.

The SDS Plus chuck accepts bits up to 1-1/8 inches, which is perfect for most of my needs. Whether I'm drilling holes for anchor bolts or chipping away at stubborn tiles, the tool handles each task with aplomb. The three-mode operation—rotary hammer, hammer only, and rotation only—adds another layer of versatility, allowing me to switch between drilling and chipping seamlessly.

Convenience and Ergonomics

One of the standout features is its cordless nature. Gone are the days of lugging around extension cords or searching for a power outlet. This freedom is especially useful on job sites without easy access to electricity. The tool's weight, at 7.7 lbs, is manageable, and even when paired with an 8.0 High Output battery, it remains well-balanced and comfortable to use over extended periods.

The anti-vibration system (AVS) significantly reduces the strain on my hands and arms, which is crucial for long workdays. The side handle and depth rod are thoughtful additions, providing better control and accuracy when drilling. Connecting and removing bits is quick and hassle-free, thanks to the efficient design of the chuck.

Battery Life and Performance

Battery life is always a concern with cordless tools, but the Milwaukee 2715-20 does not disappoint. I typically use it with an 8.0 High Output battery, which provides enough power to get through a full day of work with intermittent breaks for recharging. For all-day use, I find that two to three batteries are sufficient to keep the tool running continuously.

Drilling 1-1/8 inch holes into concrete takes about 30 seconds per 6 inches, which is impressive. The tool doesn't struggle under load, maintaining consistent performance even when tackling tougher materials. The battery level indicator is a handy feature, giving me a clear view of how much juice is left without any guesswork.

Build Quality and Durability

Milwaukee is known for its durable tools, and the 2715-20 is no exception. The build quality is top-notch, with robust materials that can withstand the rigors of a busy job site. The tool feels solid in hand, and the components seem built to last. Even after several months of heavy use, it shows no signs of significant wear.

One minor gripe is the placement of the serial number, which tends to wear off with extensive use. This could be problematic if you need to claim warranty service, as I experienced once. However, Milwaukee's customer service is responsive and accommodating, which somewhat mitigates this issue.

Practical Applications

I've used this rotary hammer across a variety of projects, from home renovations to large-scale commercial jobs. It's been incredibly useful for drilling holes for PVC pipes, running low-voltage and CAT 5 lines, and even breaking up concrete for landscaping projects. The tool's ability to handle both precision drilling and heavy-duty demolition makes it a versatile addition to any toolkit.

For instance, on a recent project involving a 20,000 sq ft building with no electricity, this tool was indispensable. It made quick work of breaking down tile walls in cramped bathrooms where swinging a sledgehammer was impossible. The compact size and cordless design allowed me to maneuver easily, even in tight spaces.

Final Thoughts

Overall, the Milwaukee 2715-20 Cordless Rotary Hammer is a powerful, versatile, and convenient tool that has significantly improved my efficiency on the job. Its cordless nature, combined with robust performance and thoughtful ergonomics, makes it a valuable asset for both professional contractors and serious DIY enthusiasts.

Would I recommend this tool? Absolutely. The benefits far outweigh the minor drawbacks, making it a solid investment for anyone who regularly works with concrete and masonry. The combination of power, durability, and convenience sets it apart from many other rotary hammers on the market. If you're looking for a tool that can handle a wide range of tasks with ease and reliability, the Milwaukee 2715-20 is well worth considering.
