Milwaukee 12" Plus-Lok SDS Plus Rotary Hammer Extension

When working on construction or renovation projects, the right tools can make all the difference. One such tool that has proven its worth in my toolkit is the Milwaukee 12" Plus-Lok SDS Plus Rotary Hammer Extension. This extension has transformed the way I handle drilling in tight and obstructed areas, providing increased access and versatility.

Design and Build Quality

The first thing I noticed about the Plus-Lok extension is its solid construction. Made from high-quality steel, it feels robust and durable right out of the box. Weighing just 0.71 lbs, it's surprisingly lightweight for its size, which makes it easy to handle without adding unnecessary strain during prolonged use. The extension measures 13 inches in height and has a width and length of 0.88 inches, making it compact enough to fit into my tool case without taking up too much space.

Compatibility

One of the standout features of this extension is its universal compatibility with all SDS Plus rotary hammers and accessories. Whether you're using drill bits, chisels, core bits, or anchor installation solutions, this extension fits seamlessly. This versatility is a significant advantage as it eliminates the need to buy multiple extensions for different tools, saving both money and storage space.

Ease of Use

The Plus-Lok extension is designed with user convenience in mind. The auto-insert mechanism allows for tool-free connection, which means you can quickly swap out accessories without fumbling with additional tools. This feature is particularly useful when you're in the middle of a project and need to change bits frequently. The sliding chuck release operates smoothly, although I did find that it could benefit from knurled surfaces for a better grip, especially when working with gloved or dirty hands.

Performance

In terms of performance, the Plus-Lok extension does not disappoint. The small diameter profile allows for drilling deep holes of 7/8" and larger, which is more than adequate for most construction tasks. I tested it on various materials, including concrete and masonry, and it delivered consistent results every time. The extension maintains the hammer action's efficiency, although there is a slight reduction in hammer power due to the additional connection. This is not a deal-breaker, but it's something to be aware of if your drill doesn't have a powerful hammer action to begin with.

Practical Applications

One of the primary reasons I added this extension to my toolkit was for drilling in tight and obstructed areas. The 12-inch length provides the extra reach needed to get into those hard-to-access spots without compromising on drilling depth. For example, when working on floor surfaces, the extension allowed me to drill holes without having to kneel, making the task much more comfortable. Similarly, when drilling overhead, I found that I often didn't need a ladder, thanks to the extension's added reach.

Durability Concerns

While the Plus-Lok extension is built to last, I did encounter some issues with rust after prolonged use. After about six weeks, I noticed significant oxidation on the shaft, which required me to lubricate the chuck release slide to restore its smooth action. This is a minor inconvenience but something to keep in mind if you plan to use the tool in humid or wet conditions. A protective coating to prevent rust would be a welcome improvement.

Value for Money

The Plus-Lok extension is not the cheapest option on the market, but its versatility and build quality justify the price. Considering that it fits all SDS Plus accessories and eliminates the need for multiple extensions, it offers good value for money. Additionally, Milwaukee's reputation for high-quality tools and excellent customer service adds to the overall appeal.

Final Thoughts

The Milwaukee 12" Plus-Lok SDS Plus Rotary Hammer Extension is a valuable addition to any professional or DIY enthusiast's toolkit. Its robust construction, universal compatibility, and ease of use make it a practical choice for a wide range of drilling tasks. While there are minor issues with grip and rust, these are outweighed by the tool's overall performance and versatility.

I would recommend this extension for anyone looking to improve their drilling capabilities, especially in tight or obstructed areas. Its ability to extend reach and maintain drilling efficiency makes it a reliable and valuable tool for various applications. Whether you're a seasoned professional or a DIY enthusiast, the Plus-Lok extension is a worthwhile investment that will undoubtedly enhance your drilling projects.
