Milwaukee Hole Dozer Bi-Metal Hole Saw

Using the Milwaukee Hole Dozer Bi-Metal Hole Saw has been quite an enlightening experience. From its robust construction to its versatile applications, this tool certainly has a lot to offer. However, as with any product, it has its strengths and weaknesses.

The first thing I noticed about the Hole Dozer was its solid build. Milwaukee has a reputation for creating durable tools, and this hole saw is no exception. The high-speed steel construction promises longevity, especially when cutting through tough materials like metal. The 3.5 TPI (teeth per inch) tooth design is optimized for a variety of materials, including metal, drywall, plastics, and wood. This versatility is a significant advantage, allowing me to use the same tool for different projects without needing to switch out saws constantly.

One of the standout features of the Hole Dozer is its access slots. These slots make plug removal much more manageable, a detail often overlooked in other hole saw designs. After drilling, the cut-out material can be easily pried out, saving time and reducing frustration. This feature is particularly beneficial when working on large projects where multiple holes need to be drilled in quick succession.

Another feature worth mentioning is the thermoset coating. This coating reduces friction, which in turn helps to keep the saw from overheating. Overheating can be a significant issue when drilling through metal, and this coating helps mitigate that problem. It also contributes to the overall durability of the tool, ensuring it remains sharp and effective for longer periods.

However, the Hole Dozer is not without its drawbacks. One of the most significant issues I encountered was the arbor system. While the tool comes with an arbor included, removing and replacing it can be a cumbersome process. The arbor tends to tighten as you drill, making it difficult to remove without the proper tools. This can be particularly frustrating if you need to switch between different hole saw sizes frequently. Additionally, the need for an adapter nut to use the arbor with smaller saws adds an extra layer of complexity and cost.

Despite these issues, the Hole Dozer performs admirably in its primary function—cutting holes. In my experience, it cuts through wood and metal with relative ease. When used on a wooden door, the saw produced a clean, even hole with minimal effort. The teeth remained sharp throughout the process, and the cut was smooth on both sides of the door. This performance is consistent with Milwaukee's reputation for quality craftsmanship.

Cutting through metal, however, was a bit more challenging. While the Hole Dozer did eventually get the job done, it took longer than expected. The saw struggled a bit with thicker metal, and I had to apply more pressure than I would have liked. This issue wasn't a deal-breaker, but it's something to keep in mind if you plan to use this tool primarily for metal applications.

One of the more unique uses I found for the Hole Dozer was in making wheels and plugs. By removing the pilot bit and using a drill press, I could create clean, precise wheels with a 1/4" axial hole. This versatility makes the Hole Dozer a valuable addition to any workshop, especially for those who enjoy DIY projects.

In terms of ergonomics, the Hole Dozer is relatively easy to handle. Its design allows for good visibility, making it easier to place the saw accurately before drilling. The hex-shaped end of the arbor ensures that it won't slip during use, providing a secure and stable drilling experience. However, the tool's weight and the need for additional tools to change the hole saw can make it less convenient for quick, on-the-go adjustments.

One aspect that impressed me was the lifetime tooth break warranty. This warranty provides peace of mind, knowing that Milwaukee stands behind the durability of their product. Given the tool's performance and build quality, I doubt I'll need to take advantage of this warranty, but it's reassuring to know it's there.

In conclusion, the Milwaukee Hole Dozer Bi-Metal Hole Saw is a well-crafted, versatile tool that performs well in various applications. Its durable construction, effective tooth design, and thoughtful features like access slots and thermoset coating make it a valuable addition to any tool collection. However, the cumbersome arbor system and the occasional struggle with thicker metal are worth considering.

Would I recommend the Hole Dozer? Yes, but with some reservations. If you're looking for a reliable, durable hole saw for general use, particularly in wood and thin metal, this tool is an excellent choice. However, if you frequently need to switch between different hole saw sizes or work primarily with thicker metal, you might find the arbor system frustrating. Overall, the Hole Dozer offers solid performance and durability, making it a worthwhile investment for most DIY enthusiasts and professionals alike.
