Milwaukee 9-in-1 Metric HEX/KEY Drive Multi-Bit Driver

As a seasoned tool enthusiast, I always appreciate a tool that offers versatility and efficiency in one compact package, and the Milwaukee 9-in-1 Metric HEX/KEY Drive Multi-Bit Driver certainly fits the bill. This multi-bit driver is designed to simplify your toolkit by combining multiple functions into a single, ergonomically designed device.

Design and Build Quality

The first thing that struck me about this Milwaukee tool is its robust build quality. Manufactured in Taiwan to Milwaukee's exacting standards, the tool exudes durability from the moment you pick it up. The handle, constructed from dual durometer materials, is both rugged and extremely comfortable to grip. This dual material construction ensures that the tool can withstand heavy use while remaining easy on the hands—a crucial feature when you're working on projects that require prolonged use.

The tool measures just over nine inches in length, with almost 4-3/4 inches from the end of the handle to the tip of the bit. This length provides excellent reach for those hard-to-access fasteners, although it does limit its use in tight spaces. The overall weight of 0.55 lbs makes it lightweight enough to carry around without feeling cumbersome.

Functionality

The 9-in-1 designation comes from its ability to function as a metric hex key driver with the included bits that range from 1.5mm to 6mm. Additionally, the handle can be used as a ¼ inch nut driver, adding to its versatility. The tool includes seven hex bits and a loop maker hole, making it a truly multi-functional device.

One standout feature is the precision-machined, chrome-plated bits. These bits offer rust protection and durability, ensuring they can withstand the test of time. Each bit features a wrench-ready hex shank, allowing for added leverage when needed. The magnetic bit retention system is another thoughtful addition, providing consistent driving performance by securely holding the bits in place. However, it's worth noting that the magnet does not extend to the tip of the bit to retain ferrous hardware, which could be a minor inconvenience in some scenarios.

Usability

One of the most practical aspects of this tool is the in-handle bit storage. Six of the seven bits can be stored within the handle, making it easy to switch between different sizes without misplacing any bits. The bits are held in place by an internal O-ring, which provides a friction fit. While this system is generally effective, I found that the smaller bits can be somewhat difficult to remove, often requiring another bit to push them out. Over time, this friction fit may become tighter, potentially making it even harder to access the bits.

The handle itself is ergonomically designed, fitting comfortably in the hand and providing excellent grip. However, its larger size might not be ideal for users with smaller hands. The tool also features a hex bolster on the shaft, allowing you to use a wrench for additional torque when needed—a feature I found particularly useful for stubborn fasteners.

Performance

In terms of performance, the Milwaukee 9-in-1 driver excels in most areas. The bits fit securely in the driver, thanks to the precision-machined tips, which ensure a snug fit in fasteners. This secure fit minimizes the risk of stripping screws, a common issue with lower-quality bits. I used this tool to assemble a piece of furniture with numerous hex head screws, and it significantly reduced the time and effort required compared to using a traditional hex key.

However, it's important to note that the smaller bits, particularly the 3mm and 2.5mm sizes, may be prone to snapping under heavy torque. This is a limitation to be mindful of, especially when working with tougher materials or fasteners.

Versatility

One of the key selling points of this tool is its compatibility with power tools. The bits' ¼ inch hex base allows them to be used in standard drivers, including power tools. This feature adds a layer of convenience, enabling you to switch between manual and powered driving without needing separate sets of bits. However, caution is advised when using the smaller bits in power tools, as they may not withstand the higher torque and speed.

Final Thoughts

The Milwaukee 9-in-1 Metric HEX/KEY Drive Multi-Bit Driver is a versatile, well-built tool that offers significant value for both professional and DIY users. Its robust construction, ergonomic design, and multi-functional capabilities make it a worthy addition to any toolkit. The in-handle bit storage and magnetic bit retention system are thoughtful features that enhance its usability, although the tight fit of the bits may require some getting used to.

While the tool's length may limit its use in tight spaces and the smaller bits may be prone to snapping, these are relatively minor drawbacks compared to the overall benefits. The ability to use the bits in power tools further adds to its versatility, making it a practical choice for a wide range of applications.

Recommendation

I would highly recommend the Milwaukee 9-in-1 Metric HEX/KEY Drive Multi-Bit Driver to anyone looking for a reliable, multi-functional tool that can handle a variety of tasks. Its combination of quality, comfort, and versatility makes it an excellent investment for both professionals and hobbyists. Whether you're assembling furniture, working on electronics, or tackling home improvement projects, this tool is designed to make your job easier and more efficient.
