Milwaukee Extreme Thin Metal Band Saw Blades

As someone who has spent countless hours in the workshop, I’m always on the lookout for tools that promise efficiency and durability. The Milwaukee Extreme Thin Metal Band Saw Blades (model 48-39-0613) seemed like a promising addition to my toolbox, especially given their reputation for cutting various metals efficiently. However, my experience with these blades has been a mixed bag, to say the least.

Initial Impressions

Upon unboxing, the Milwaukee band saw blades appear well-made. The pack of 100 blades in the 44 7/8" size with 12/14 TPI (teeth per inch) seemed like a solid investment for someone who needs to cut a variety of metal thicknesses. The blades are manufactured in the USA, which often speaks to a higher standard of quality. The promise of increased cutting efficiency and a long lifespan, particularly with stainless steel and other metals, was appealing.

Performance in the Workshop

The first few cuts with these blades were impressive. They sliced through thin metal with ease, and the variable TPI design allowed for clean, precise cuts. The initial performance gave me hope that these blades would live up to Milwaukee’s reputation for quality.

However, as I continued to use the blades, I began to notice some significant issues. After a few cuts, the blades started to dull noticeably. This was particularly apparent when cutting through tougher materials like cast iron and EMT (electrical metallic tubing). The blades that initially cut through metal like butter began to struggle, requiring more effort and time to complete the same tasks.

Durability Concerns

One of the most disappointing aspects of these blades is their durability. In my experience, several blades snapped at the welds after only a few uses. This is particularly frustrating because a broken blade not only interrupts your workflow but also adds to the overall cost of the project. I expected these blades to last longer, especially given their premium price point.

Another issue I encountered was the formation of cracks along the blades. Even when the teeth remained sharp, the structural integrity of the blades was compromised, leading to breakages. This is not what I expected from a brand like Milwaukee, which is known for its durable and reliable tools.

Cutting Efficiency

While the blades performed well initially, their efficiency dropped significantly after a few uses. This was particularly noticeable when cutting through thicker or harder metals. The blades seemed to struggle, and the cuts were not as clean as I would have liked. This inefficiency not only slowed down my work but also led to increased wear and tear on the blades.

Versatility

The variable TPI design is supposed to offer versatility for cutting different metal thicknesses, but in practice, this feature did not make up for the blades' lack of durability. While the blades were initially effective for a range of materials, their rapid decline in performance made them less versatile than I had hoped. For instance, cutting through threaded rods and schedule 40 pipes proved to be more challenging than anticipated, and the blades dulled quickly.

Manufacturing Quality

Given that these blades are manufactured in the USA, I had high expectations for their quality. Unfortunately, the issues with blade breakage and rapid dulling suggest that there may be inconsistencies in the manufacturing process. It's possible that I received a bad batch, but the frequency of these issues indicates that they may be more widespread.

Final Thoughts

After using the Milwaukee Extreme Thin Metal Band Saw Blades extensively, I have mixed feelings. On the one hand, they offer impressive initial performance and the convenience of a versatile TPI design. On the other hand, their lack of durability and tendency to break at the welds make them less reliable for long-term use.

If you’re working on a project that requires only a few cuts, these blades might serve you well. However, for more extensive or demanding tasks, you might find yourself frustrated by their short lifespan and tendency to break. Given these issues, I find it hard to recommend these blades for professional use, especially when there are other brands on the market that offer more reliable performance.

In conclusion, while the Milwaukee Extreme Thin Metal Band Saw Blades have some positive attributes, their significant drawbacks make them a less-than-ideal choice for demanding metal cutting tasks. Until Milwaukee addresses these issues and improves the durability of these blades, I would recommend looking into alternative options that offer better reliability and longevity.
