Milwaukee Extreme Thin Metal Band Saw Blades

Cutting metal can be a demanding task, and having the right blade makes all the difference. That’s why I decided to test out the Milwaukee Extreme Thin Metal Band Saw Blades (model 48-39-0615), which promise an aggressive tooth design, longer blade life, and compatibility with a variety of metals. Here’s my detailed breakdown of how these blades performed in a real-world setting.

Initial Impressions

Right out of the box, the blades felt robust and well-crafted. The 44 7/8-inch length is compatible with many portable band saws, making it a versatile choice for various cutting tasks. The blades feature a bi-metal construction and a variable tooth pitch of 12/14 TPI, which is designed to handle both thin and thicker metals efficiently.

Installation and Setup

Installing the blades was straightforward. They fit snugly into my Milwaukee M18 band saw, and the process was no different from any other blade installation. One thing I did notice is that these blades are a bit thicker and less bendable than other blades I’ve used in the past. This added rigidity did make the installation slightly more cumbersome, but it’s a minor inconvenience for what promised to be a more durable blade.

Cutting Performance

Once set up, I put the blades through their paces on a variety of metal types, including stainless steel, aluminum, and cast iron. The aggressive tooth design was immediately noticeable. The blades made quick work of thin metals like conduit and thin-walled tubing, producing smooth, clean cuts with minimal burrs.

When it came to thicker materials, the blades still performed admirably, though I did have to be patient and let the weight of the saw do the work to avoid pushing too hard and potentially damaging the teeth. One impressive test was cutting through 3/8-inch structural steel, which the blades handled without much trouble. The variable TPI design really shines here, as it minimizes vibration and chatter, making for a smoother cutting experience.

Durability

Durability is where these blades had mixed results. Over extended use, I found that the blades maintained their edge well when cutting less demanding materials like aluminum and conduit. However, when tasked with tougher jobs, such as cutting cast iron or thicker stainless steel, the blades dulled quicker than I expected. In some instances, I noticed that the welded sections of the blades would fail, causing the blade to snap.

Despite these issues, when used correctly and not forced through the material, the blades offered a respectable lifespan, especially considering the aggressive cutting they provide. It’s worth noting that pushing the blades too hard or using them for tasks they’re not designed for can significantly shorten their lifespan.

Value and Pack Quantity

One of the most appealing aspects of these blades is the pack quantity. The 25-pack option provides good value for those who use their band saws frequently. The cost per blade is reduced significantly when buying in bulk, making it a cost-effective choice for professionals who need reliable performance over a long period.

Pros and Cons

Pros:

• Aggressive Tooth Design: Cuts through thin and thick metals efficiently.
• Variable TPI: Reduces vibration and provides smoother cuts.
• Compatibility: Fits a wide range of portable band saws.
• Good Value: The 25-pack option offers significant savings.

Cons:

• Durability Issues: Blades can dull quickly on tougher materials.
• Weld Failures: Some blades snapped at the welds under heavy use.
• Installation: Slightly more rigid and harder to install due to thickness.

Final Thoughts

Overall, the Milwaukee Extreme Thin Metal Band Saw Blades deliver on many of their promises. They offer fast and clean cuts, especially in thin metals, and the variable TPI design is a standout feature that makes a noticeable difference in cutting performance.

However, the durability concerns cannot be overlooked. While the blades are well-suited for less demanding tasks, they may not hold up as well under heavy-duty use. This is something to consider depending on your specific needs.

Would I Recommend These Blades?

If you’re a professional or a serious DIYer who frequently cuts thin to medium-thick metals, the Milwaukee Extreme Thin Metal Band Saw Blades are a solid choice. They offer good value, excellent cutting performance, and the convenience of a bulk pack.

However, if your work involves consistently cutting very thick or particularly tough materials, you might want to consider alternatives that offer better durability. These blades excel in specific scenarios but may not be the all-around solution for everyone.

In conclusion, while these blades have their limitations, they are a valuable addition to any tool kit for those who understand their strengths and use them accordingly.
