Milwaukee 78”/32” Magnetic Box Level Jamb Set

When it comes to precision and reliability in the world of leveling, Milwaukee's 78”/32” Magnetic Box Level Jamb Set stands out as a robust and thoughtfully designed tool. As someone who regularly tackles various construction and DIY projects, I found these levels to be indispensable additions to my toolkit. Let's break down what makes this set noteworthy and where it might fall short.

Build Quality and Durability

The first thing that struck me about these levels is their build quality. Milwaukee has clearly put a lot of thought into the construction of these tools. Both the 78-inch and 32-inch levels feature an ALL-METAL BACKBONE™ for enhanced durability. This design choice makes the levels feel incredibly sturdy and capable of withstanding the rigors of job site use. The high-density, removable end-caps provide additional protection, ensuring that the levels can survive accidental drops and bumps.

The aluminum frame is not only durable but also precisely machined. I tested the straightness of both levels using a granite surface plate and feeler gauges. The results were impressive, with the 78-inch level showing only a minuscule variation of .0015 inches over its entire length. The 32-inch level was dead flat, making these tools highly reliable for tasks that require pinpoint accuracy.

Readability and Vial Technology

One of the standout features of these levels is the SHARPSITE™ Vial Technology. The vials are larger than those found on most other levels, making them easy to read from various angles and distances. The high contrast vial system also ensures visibility in different lighting conditions, from dimly lit rooms to bright outdoor settings. This is particularly useful when you're working in less-than-ideal lighting conditions and need to make quick, accurate adjustments.

The vials are guaranteed for lifetime accuracy with an impressive rating of .029°, which translates to .0005 inches per inch. This level of precision is more than sufficient for any construction or DIY project, ensuring that your work is always on the mark.

Magnetic Holding Power

The magnetic capability of these levels is another feature worth noting. The 78-inch level is equipped with amplified rare earth magnets that provide maximum holding power. This is particularly useful when working with steel frames or other metal surfaces. The magnets are strong enough to hold the level securely in place, allowing for hands-free operation.

However, the 32-inch level falls short in this department. It only has two magnets, which significantly reduces its holding power. I found that it often slipped off metal surfaces, especially when used horizontally. This is a notable drawback, as it compromises the tool's usability in certain scenarios.

Usability and Comfort

Milwaukee has also paid attention to user comfort and ease of use. Both levels feature wide handles that are easy to grip, even when wearing gloves. The overmolded, non-slip grips further enhance handling, preventing the levels from sliding during use. The precision-milled measuring surface ensures that the levels sit flat against surfaces, providing accurate readings every time.

The levels are also designed with convenience in mind. The durable, all-metal hang hole allows for easy storage, and the high-density end-caps can be removed to fit the levels into tight spaces. These thoughtful design elements make the levels versatile tools that can adapt to a variety of tasks.

Performance in Real-World Applications

In practical use, the 78-inch level proved invaluable for tasks like checking door jambs and aligning beams. Its length provides a larger reference surface, making it easier to identify high and low spots on walls, floors, and ceilings. The 32-inch level, despite its weaker magnets, is still useful for smaller projects and tight spaces.

During my testing, I used the levels to re-align bedroom doors and check the flatness of plywood sheets. The large, easy-to-read vials and the sturdy construction made these tasks straightforward and efficient. The levels' accuracy and durability gave me confidence that the job was being done right the first time, reducing the need for rework.

Areas for Improvement

While the Milwaukee Magnetic Box Level Jamb Set has many strengths, it is not without its flaws. The most significant issue is the weak magnetic holding power of the 32-inch level. This limits its usefulness in certain applications and can be frustrating when the level slips off metal surfaces.

Another minor gripe is the weight of the levels. They are heftier than many other levels on the market, which can be a drawback if you need to use them overhead for extended periods. However, this weight also contributes to their durability, so it's a trade-off that might be acceptable for many users.

Final Thoughts

Overall, the Milwaukee 78”/32” Magnetic Box Level Jamb Set is a high-quality, reliable tool that excels in many areas. Its robust construction, precise machining, and easy-to-read vials make it a valuable addition to any toolkit. The strong magnets on the 78-inch level and the user-friendly design further enhance its appeal.

However, the weak magnets on the 32-inch level and the tool's weight are notable drawbacks. If your work frequently involves metal surfaces and you need a level that stays put, you might want to consider other options for the smaller level. Despite these issues, the set's overall performance and durability make it a worthwhile investment for both professionals and serious DIYers.

In conclusion, I would recommend the Milwaukee Magnetic Box Level Jamb Set for its accuracy, build quality, and ease of use. While it has some areas for improvement, its strengths far outweigh its weaknesses, making it a reliable tool for a wide range of leveling tasks.
