Milwaukee 8" Metal Cutting Saw

The Milwaukee 8" Metal Cutting Saw, model 6370-20, has been a game-changer in my metalworking projects. As someone who frequently works with various types of metal, I needed a tool that could offer precision, power, and safety. This saw not only met those criteria but exceeded my expectations in several areas.

Design and Build Quality

The first thing I noticed about this saw is its robust build. Weighing in at 13.3 lbs, it’s not the lightest tool, but that weight contributes to its stability during cuts. The saw features a durable blade shield that effectively collects metal shavings, minimizing the mess and making it safer to handle freshly cut materials. The design also includes a soft grip handle, which adds to the comfort, especially during extended use.

However, the base plate has room for improvement. It feels somewhat flimsy and can be challenging to keep aligned with a straight edge guide for long cuts. This is a minor inconvenience, but it’s worth noting for those who require precise, straight cuts over extended lengths.

Performance

The performance of this saw is where it truly shines. Equipped with a 15-amp motor and a no-load RPM of 3,700, it cuts through metal like a hot knife through butter. I’ve used it on a variety of materials, including 14 gauge steel, 1/8" thick steel, and even 3/16" diamond plate stainless steel. In every instance, the saw delivered clean, burr-free cuts with minimal heat. This is largely due to its dry-cut technology, which eliminates the need for lubricants and reduces the risk of warping the material.

One of the standout features is the plunge lever, which makes it easy to perform plunge cuts. This is particularly useful for cutting out sections of metal that are already installed or for making intricate cuts. The quick-release shield latch is another thoughtful addition, making it easy to dispose of waste and change blades without fuss.

Safety and Usability

Safety is always a concern when working with power tools, especially those that cut through metal. The Milwaukee 8" Metal Cutting Saw addresses this with a well-designed blade shield and integral chip tank. The chip tank collects most of the hot metal shavings, reducing the risk of burns or fires. However, it’s still advisable to wear eye protection, gloves, and long sleeves, as some hot chips can escape.

The saw also features a spindle lock, which makes blade changes straightforward and safe. One area where it falls short is the lack of an electrical brake. This means the blade continues to spin for a few seconds after releasing the trigger, so you need to be cautious when setting the saw down.

Durability

Durability is another strong point for this saw. The construction is grounded, and the materials used feel high-quality. Despite a few concerns about the base plate’s attachment, the overall build is solid. I’ve dropped the saw from a modest height without any significant damage, although I’d recommend avoiding such mishaps to extend its lifespan.

Chip Collection and Cleanup

The chip collection system is quite effective, capturing most of the metal shavings in an integral chip tank. This not only keeps your workspace cleaner but also makes the saw safer to use. However, it doesn’t capture all the shavings, so be prepared for some cleanup afterward. The quick-release shield latch simplifies the process, allowing you to empty the chip tank without disassembling the saw.

Versatility

One of the aspects I appreciate most about this saw is its versatility. It’s not just a one-trick pony; it can handle a wide range of materials and thicknesses. From thin sheets of metal to thicker, more robust materials, this saw cuts through them all with ease. I’ve even used it to cut wood with embedded nails and rebar, and it performed admirably.

Drawbacks

While this saw has many strengths, it’s not without its drawbacks. The most significant issue is the base plate’s flimsiness, which can affect the accuracy of long cuts. Additionally, the lack of an electrical brake means you need to be extra cautious when ending a cut. These are relatively minor issues in the grand scheme of things, but they’re worth considering.

Conclusion

In summary, the Milwaukee 8" Metal Cutting Saw is a powerful, reliable tool that excels in cutting various types of metal. Its robust build, effective chip collection system, and versatile performance make it a valuable addition to any metalworker’s toolkit. Despite a few minor drawbacks, such as the flimsy base plate and the absence of an electrical brake, the saw’s strengths far outweigh its weaknesses.

Would I recommend this tool? Absolutely. Its ability to deliver clean, precise cuts with minimal heat and burrs makes it an excellent choice for both professional and hobbyist metalworkers. The saw's durability and thoughtful design features, such as the plunge lever and quick-release shield latch, further enhance its usability. If you’re in the market for a high-quality metal cutting saw, the Milwaukee 8" Metal Cutting Saw should be at the top of your list.
