Milwaukee 18 Gauge Single Cut Shear

Milwaukee has long been a trusted name in the realm of power tools, and their 18 Gauge Single Cut Shear (model number: 2637-20) is no exception. As someone who frequently works with metal, I've had the opportunity to put this tool through its paces, and I must say, it has left quite an impression—both good and bad. Here’s my detailed breakdown of this tool.

Design and Ergonomics

The first thing that catches your eye about this shear is its redesigned body and ergonomic design. Milwaukee has clearly put thought into making this tool as user-friendly as possible. The inline wrist design enhances control, making it easier to handle during extended use. The tool itself is 16.5 inches long and weighs 4.2 pounds, which provides a nice balance between heft and maneuverability.

One standout feature is the 360º tool-free rotating head. This allows for greater versatility, enabling you to make cuts at various angles without having to contort your body or the material you're working on. The variable speed trigger is another excellent addition, giving you precise control over the cutting speed based on the material you're working with.

Cutting Performance

When it comes to cutting capabilities, the Milwaukee shear does not disappoint. It can cut through 18 gauge steel and 20 gauge stainless steel with ease. I've used it on everything from metal studs to sheet metal and metal roofing, and it slices through these materials like butter. The cuts are clean and smooth, a significant improvement over the ragged edges often left by hand snips. The minimum cut diameter is 3 inches, which is more than sufficient for most tasks.

However, there are some caveats. The rotating head, while useful, has a bit of play in it. This can make it challenging to achieve long, straight cuts. It's a minor inconvenience but worth noting if precision is crucial for your projects.

Battery Life and Compatibility

The shear runs on Milwaukee's M18™ battery system, which is a huge plus. The batteries are long-lasting and provide ample power for extended use. The fact that the batteries are compatible with all other M18™ tools adds to the overall value, making it a versatile addition to any toolkit.

In my experience, the battery life has been more than adequate for a full day’s work. The kit I used came with two high-capacity lithium-ion batteries, a 12/18V charger, and a carrying case, making it a comprehensive package right out of the box. The batteries even have a built-in power gauge, so you always know how much juice you have left.

Durability and Maintenance

Durability is where this tool shows some mixed results. On the one hand, the shear is robust and well-built, designed to withstand daily use in demanding environments. On the other hand, the blades are a bit of a sticking point. While they perform exceptionally well, replacement blades are expensive. The cost of replacing both the center and lower cutters can be almost as much as the tool itself, which is a significant drawback.

Moreover, the warranty does not cover the blades, which adds to the maintenance costs. This is something to consider if you plan on using the shear extensively, as blade replacement will be inevitable over time.

Practicality and Usability

In practical terms, this tool has been a game-changer for my metalworking projects. The cordless design is incredibly liberating, allowing me to move freely without worrying about dragging a cord around. This is especially useful in tight or elevated workspaces where a cord could become a tripping hazard.

The shear also excels in versatility. Whether you're making straight cuts, curved cuts, or cutting through the ribs of metal sheets, it handles it all with aplomb. The ergonomic design and variable speed control make it easy to use for extended periods without experiencing significant hand fatigue.

Final Thoughts

The Milwaukee 18 Gauge Single Cut Shear is a powerful, versatile tool that excels in many areas but falls short in a few. Its ergonomic design, cutting performance, and battery life are top-notch, making it a valuable addition to any metalworker's toolkit. However, the high cost of replacement blades and the slight play in the rotating head are notable drawbacks.

Would I recommend this tool? Yes, but with reservations. If you're looking for a reliable, high-performing shear that can handle a variety of cutting tasks, this Milwaukee model is a solid choice. However, be prepared for the ongoing cost of replacement blades, and consider whether the slight imprecision in the rotating head will affect your work.

In summary, the Milwaukee 18 Gauge Single Cut Shear is not perfect, but its strengths far outweigh its weaknesses. For those in the HVAC, metal roofing, or general metalworking industries, this tool can save you time and effort, making it a worthy investment.
