Milwaukee 1/2" Hammer Drill/Driver

The Milwaukee 1/2" Hammer Drill/Driver (model 2404-20) is a tool that has garnered quite a bit of attention in the power tool community, and for good reason. After spending a considerable amount of time using it in various scenarios, I feel equipped to share a comprehensive review of its performance, strengths, and areas for improvement.

Design and Build Quality

At first glance, the Milwaukee Hammer Drill/Driver impresses with its compact and lightweight design. Weighing in at just 2.5 lbs, it’s easy to handle and maneuver, especially in tight spaces where larger drills would be cumbersome. The tool measures 7.75 inches in length, which makes it remarkably portable and suitable for extended use without causing arm fatigue.

The build quality is robust, with a good balance of metal and high-quality plastic components. The tool features a solid 1/2" metal single sleeve ratcheting chuck that provides excellent bit retention, ensuring that bits stay firmly in place even during intensive tasks. This feature alone instills confidence in the tool’s durability and longevity.

Power and Performance

Under the hood, this drill is equipped with a brushless motor that delivers a peak torque of 350 in-lbs and speeds ranging from 0-450 RPM in low gear and 0-1,700 RPM in high gear. The brushless motor is a standout feature, offering better efficiency and longer lifespan compared to brushed motors.

In practice, the drill performs admirably across a range of materials. I’ve used it to drill into drywall, studs, and even masonry, and it handled each task with ease. The hammer function is particularly effective, delivering up to 25,500 BPM, which makes quick work of concrete and brick. It’s worth noting that while the hammer function adds a bit of weight and vibration, it’s a trade-off that’s well worth it for the added versatility.

Battery Life and Management

The Milwaukee Hammer Drill/Driver is part of the M12 system, and it comes with an onboard fuel gauge that allows you to monitor the battery charge. This is a small but highly practical feature, sparing you the sudden interruptions that come with unexpected battery depletion.

I tested the tool with both the standard 2.0Ah and 4.0Ah batteries, and the results were mixed. While the tool performs well with the 4.0Ah battery, providing reasonable battery life and cooler operation, the 2.0Ah battery tends to drain quickly and cause the tool to heat up. For optimal performance, I highly recommend using the High Output (HO) batteries, which significantly improve both battery life and the tool’s overall efficiency.

Ergonomics and Usability

Comfort is another area where this drill shines. The grip is coated in a nonslip rubber overmold, making it comfortable to hold and reducing hand fatigue during prolonged use. However, some users might find the grip a bit bulky due to the battery placement, which could be a minor inconvenience for those with smaller hands.

The tool also features an LED light positioned under the chuck, which illuminates the work area effectively. This is particularly useful in dimly lit environments, ensuring precise and accurate drilling.

One area where the tool could improve is the inclusion of a side handle. Given the torque this drill can generate, having an additional handle would provide better control and reduce wrist strain during high-torque applications.

Versatility and Applications

This drill is highly versatile, capable of handling a wide range of tasks from light DIY projects to more demanding professional applications. I particularly appreciate the ease with which it transitions between drilling, driving, and hammer drilling modes. The mechanical clutch offers 12 positions plus the hammer position, allowing for precise control over torque settings.

In practical terms, I’ve used this drill for everything from assembling furniture and installing shelves to drilling into masonry for anchor bolts. Its compact size makes it ideal for working in confined spaces, such as under sinks or inside cabinets, and its lightweight design means you can carry it around all day without undue strain.

Noise and Vibration

One point to consider is the noise level. This drill can be quite loud, especially when used indoors or in enclosed spaces. If you’re planning to use it for extended periods, ear protection is advisable. The vibration is also noticeable, particularly in hammer mode, but it’s manageable and to be expected given the tool’s capabilities.

Conclusion

In summary, the Milwaukee 1/2" Hammer Drill/Driver is a compact, powerful, and versatile tool that excels in a variety of applications. Its brushless motor delivers reliable performance, and the tool’s ergonomic design ensures comfort during extended use. While the battery performance could be improved with standard batteries, the tool truly shines when paired with HO batteries.

I would recommend this tool for both DIY enthusiasts and professionals. Its combination of compact size, power, and versatility makes it an excellent addition to any toolkit. Whether you’re drilling into wood, metal, or masonry, this drill is up to the task. Just be prepared to invest in the HO batteries to get the most out of its capabilities and ensure you have ear protection for those loud indoor jobs.
