Milwaukee M12 Cordless Lithium-Ion No-Hub Driver Kit

Milwaukee’s M12 Cordless Lithium-Ion No-Hub Driver Kit, model 2455-22, is a specialized tool designed to streamline the process of fastening no-hub couplings. As a professional who frequently works with plumbing installations, I had the opportunity to put this tool through its paces on various job sites. Here's my detailed review based on my hands-on experience.

Build and Design

The first thing that stands out about the M12 No-Hub Driver is its build quality. Milwaukee is known for producing robust tools, and this one is no exception. The tool feels solid in hand, and despite its compact size (7.5 inches in length and weighing just 2.35 lbs), it exudes durability. The design is ergonomic, making it comfortable to use for extended periods without causing hand fatigue. The built-in LED light is a thoughtful addition, providing excellent visibility in dimly lit work areas—a common scenario in plumbing tasks.

Performance

The M12 No-Hub Driver is powered by a 12-volt motor that offers adjustable torque settings of 60 in-lbs and 80 in-lbs. This range is ideal for most no-hub coupling applications, ensuring that the tool can handle both standard and more demanding tasks. One of the standout features is the auto shut-off mechanism, which activates when the preset torque limit is reached. This not only ensures accuracy but also prevents over-tightening, which can be a significant issue with manual torque wrenches.

In practice, the auto shut-off worked flawlessly. The LED indicator light provides a clear signal when the desired torque is achieved, allowing me to work quickly and efficiently. The tool also features a drill mode with a speed range of 0-750 RPM. While this mode is not its primary function, it's a handy addition for general drilling and fastening tasks, making the M12 No-Hub Driver a versatile tool to have in your kit.

Battery Life and Charging

Battery life is always a concern with cordless tools, but the M12 No-Hub Driver excels in this area. The 12V lithium-ion battery system provides ample power for a full day’s work. On a single charge, I was able to fasten numerous no-hub couplings without needing to swap out the battery. The on-board fuel gauge is a practical feature, allowing me to monitor the battery charge level easily. When it does come time to recharge, the process is quick, with the battery reaching full charge in about 30 minutes.

Durability and Reliability

While the tool performs admirably in ideal conditions, it does have some limitations. One notable drawback is its vulnerability to moisture. During one of my projects, I encountered a light mist, and the tool stopped working. Given that plumbing can often involve wet environments, this is a significant downside. Milwaukee could improve this tool by making it more resistant to moisture, ensuring reliability in all conditions.

Practicality and Ease of Use

The M12 No-Hub Driver significantly speeds up the installation process, especially when compared to manual torque wrenches. The tool's precision and repeatability are its strongest suits, ensuring that each coupling is fastened to the exact specification. This not only saves time but also reduces the physical strain on the user, which is particularly beneficial during large-scale installations.

However, it's worth noting that the tool is slightly larger and heavier than the standard M12 drill. While it still fits in a typical cordless drill holster, the added bulk may be a consideration for those who prioritize compactness in their tools. Despite this, the benefits far outweigh the minor inconvenience of its size.

Versatility

Although the M12 No-Hub Driver is a specialized tool, its versatility cannot be overlooked. The drill mode allows it to be used for a variety of tasks beyond just fastening no-hub couplings. Whether you're switching to a screwdriver tip for split ring hangers or using a socket adapter for strut clamps, this tool adapts well to different needs.

Conclusion

In summary, the Milwaukee M12 Cordless Lithium-Ion No-Hub Driver Kit is an impressive tool that delivers on its promises of accuracy, efficiency, and durability. Its adjustable torque settings, auto shut-off feature, and long battery life make it a valuable addition to any plumber's toolkit. The built-in LED light and on-board fuel gauge further enhance its practicality, making it a reliable companion on the job site.

However, the tool's susceptibility to moisture is a notable drawback that Milwaukee should address in future iterations. Despite this, the M12 No-Hub Driver remains a highly effective tool for fastening no-hub couplings, saving both time and effort.

Would I recommend this tool? Absolutely. For professionals who frequently work with no-hub couplings, the M12 No-Hub Driver is a game-changer. Its precision, ease of use, and efficiency make it well worth the investment. Just be mindful of its limitations in wet conditions, and you'll find this tool to be an invaluable asset in your plumbing projects.
