Milwaukee 1-1/4" Hole Dozer Bi-Metal Hole Saw

Navigating the vast world of tools, I recently had the opportunity to test out Milwaukee's 1-1/4" Hole Dozer Bi-Metal Hole Saw. Given Milwaukee's reputation for quality and durability, I was eager to see how this tool would perform in the field. Spoiler alert: it did not disappoint, but there are some caveats.

What immediately stands out about the Hole Dozer is its robust design and specific features tailored for both metal and wood applications. The 3.5 TPI (teeth per inch) tooth design is explicitly engineered for durability, especially in metal cutting scenarios. This design helps the saw retain its sharpness longer, which is crucial when working with tougher materials.

One of the most practical features I noticed was the access slots for easy plug removal. This might seem like a minor detail, but anyone who's spent time meticulously poking out plugs from a hole saw knows the frustration. These slots make the process significantly more efficient, allowing for quicker transitions between cuts. This is particularly beneficial when you’re working on a project with multiple holes.

The Thermoset Coating is another standout feature. This coating reduces friction, making for smoother and faster cuts. I tested the Hole Dozer on a variety of materials, including stainless steel, mild steel, and wood. In each case, the saw cut through with minimal resistance. The reduced friction is especially helpful when using cordless drills, as it helps conserve battery life and maintain performance.

However, it's not all sunshine and rainbows. During my testing, I did encounter some issues with edge retention. While the saw performed admirably on initial cuts, I noticed a decline in sharpness after extended use on harder materials like stainless steel. This isn’t entirely unexpected, as cutting through metal is demanding on any saw, but it’s worth noting if you have extensive metal cutting in your plans.

Despite this, the saw's performance in wood and softer metals was impressive. It handled a 2x6 pine board and aluminum with ease, making clean and precise cuts. The visible access slots also aid in accurate placement, ensuring that your holes are where you intend them to be.

Speaking of accuracy, the Hole Dozer’s pilot bit system is another feature worth highlighting. The pilot bit helps guide the hole saw, reducing the chances of the saw wandering off course. This is particularly useful when precision is paramount, such as when drilling holes for plumbing or electrical installations.

One notable experience was using the Hole Dozer to drill a hole in a thick steel pipe. The saw chewed through the steel with surprising ease, almost as if it were cutting through butter. The fact that it retained its sharpness after multiple holes was a testament to its build quality.

However, I did encounter an issue with one hole saw that was not perfectly round. This manufacturing defect caused the saw to wobble, resulting in uneven holes and a potentially dangerous situation. It’s crucial to inspect the tool before use to ensure it’s in proper working condition. This kind of quality control issue can be a significant drawback, especially when safety is a concern.

On a more positive note, the saw’s performance in softer materials was stellar. I used it to drill holes in a plastic cutting board and a fiberglass boat, both of which it handled effortlessly. The cuts were clean and well-defined, and the tool showed no signs of wear after several uses.

The Hole Dozer also comes with a Lifetime Tooth Break Warranty, which is a reassuring feature. Knowing that Milwaukee stands behind their product adds a layer of confidence when making the purchase. This warranty is particularly appealing given the mixed results I experienced with edge retention.

Another consideration is the tool's weight and size. At 0.19 lbs, it’s lightweight and easy to handle, reducing fatigue during prolonged use. The compact size also makes it easy to maneuver in tight spaces, which is a significant advantage for both professional tradespeople and DIY enthusiasts.

In conclusion, the Milwaukee 1-1/4" Hole Dozer Bi-Metal Hole Saw is a versatile and robust tool that performs well across a range of materials. Its standout features, including the 3.5 TPI tooth design, access slots for easy plug removal, and Thermoset Coating, make it a valuable addition to any toolkit. However, potential quality control issues and variable edge retention mean it’s essential to inspect the tool before use and be mindful of its limitations.

Would I recommend the Hole Dozer? Yes, but with reservations. For general-purpose use and softer materials, it’s an excellent choice. Its ease of use and practical features make it a joy to work with. However, if your primary need is for heavy-duty metal cutting, you may want to consider additional options or be prepared for more frequent replacements. Overall, the Hole Dozer delivers on most of its promises and is a solid investment for a wide range of applications.
