Milwaukee 1-3/4” SDS Max Rotary Hammer w/ ONE KEY

The Milwaukee 1-3/4” SDS Max Rotary Hammer w/ ONE KEY (model 2718-20) stands out prominently in a crowded field of professional-grade rotary hammers. As someone who frequently tackles heavy-duty masonry and concrete drilling tasks, I was eager to see how this cordless beast would perform. Spoiler alert: it did not disappoint.

Design and Build Quality

Right out of the box, the first thing that strikes you is the build quality. The tool is robust, with a solid feel that immediately conveys durability. Weighing in at nearly 20 pounds without the battery, it’s clear that this tool is designed for serious work. However, despite its weight, the ergonomic design manages to make it surprisingly manageable. The adjustable side handle and shock-absorbing features on both handles are noteworthy for reducing fatigue during extended use.

Performance

This rotary hammer is powered by Milwaukee’s POWERSTATE Brushless Motor, and it’s a powerhouse. It generates 8.1 ft-lbs of impact energy, and with a speed of 380 RPM and 2,900 BPM, it’s more than capable of tackling tough materials like reinforced concrete and basalt rock. I found it comparable to a 15A corded rotary hammer in terms of power, which is quite a feat for a cordless tool.

In my own projects, I used it to drill several deep holes in hard concrete and chisel away old tiles and mortar. The tool performed admirably, showing no signs of slowing down even after prolonged use. The AUTOSTOP™ E-Clutch feature is particularly impressive, stopping the tool within 45 degrees of rotation if the bit gets stuck. This feature is a lifesaver, especially when working in tight spaces or on ladders.

Battery Life and Management

Battery life is often a concern with cordless tools, and this model is no exception. Equipped with two M18 REDLITHIUM high output HD12.0 Ah batteries, the runtime is adequate but not exceptional. Each battery provides about 20 minutes of continuous heavy-duty use, such as chiseling concrete. This might seem short, but considering the tool’s power output, it’s understandable. The batteries charge relatively quickly, taking about 96 minutes to reach full capacity with the included Rapid Charger.

For optimal performance, having multiple batteries on hand is advisable. In professional settings where downtime can be costly, investing in additional batteries and perhaps a multi-battery charger would be wise.

ONE-KEY™ Compatibility

The ONE-KEY™ technology adds a layer of modern convenience, allowing you to track, manage, and customize the tool’s performance through a smartphone app. While this feature may not be crucial for everyone, it’s invaluable for professionals managing multiple tools across various job sites. The ability to lock the tool remotely if it’s lost or stolen is a noteworthy security feature.

Usability and Comfort

Despite its heft, the Milwaukee rotary hammer is surprisingly easy to use. The vibration control systems are effective, and the tool feels balanced in hand. The LED light is a small but appreciated addition, illuminating the work area well. Switching between modes (drill, hammer-drill, and hammer only) is straightforward, and the controls are intuitive, even when wearing gloves.

One minor gripe is the absence of a depth gauge, which would have been useful for precise drilling tasks. Additionally, the lack of a reverse mode means you’ll need to find alternative ways to free a stuck bit.

Versatility

The tool’s versatility is another strong point. It supports a wide range of SDS Max bits, and with an adapter, it can also use SDS Plus bits. This makes it suitable for various applications, from drilling large holes to chiseling and even driving ground rods. The ability to rotate the chisel to the most comfortable angle before use is another practical touch, enhancing the tool’s overall usability.

Cost and Value

There’s no denying that this is a premium tool with a premium price tag. However, the level of performance, build quality, and added features like the AUTOSTOP E-Clutch and ONE-KEY technology justify the investment. For professionals who need a reliable, powerful, and versatile rotary hammer, the Milwaukee 1-3/4” SDS Max Rotary Hammer is a sound choice.

Conclusion

Would I recommend the Milwaukee 1-3/4” SDS Max Rotary Hammer w/ ONE KEY? Absolutely. The tool delivers impressive power, solid build quality, and thoughtful features that enhance both safety and usability. While the battery life could be better, this is a common trade-off for the convenience of cordless operation. For professionals who require a robust, versatile, and reliable rotary hammer, this model is an excellent investment. It may be overkill for casual DIYers, but for those tackling heavy-duty tasks regularly, it’s a game-changer.
