Milwaukee Hole Dozer Bi-Metal Hole Saw

There's a certain satisfaction that comes with finding a tool that not only meets but exceeds expectations, and the Milwaukee Hole Dozer Bi-Metal Hole Saw is one such tool. From the moment I unpacked it, I could tell it was designed with both durability and efficiency in mind. The bi-metal construction with 8% cobalt makes it robust, promising a longer lifespan, especially when tackling tough materials.

Design and Durability

The Hole Dozer sports a sleek design, and its build quality is immediately apparent. One of the standout features is the Lifetime Tooth Break Warranty, which speaks volumes about the confidence Milwaukee has in this product. The teeth are aggressive yet precise, designed to handle a variety of materials from wood to metal without losing their edge quickly. I particularly appreciated the thermoset coating, which not only aids in faster cutting but also reduces friction and heat build-up, ensuring that the saw remains sharp and effective for a longer period.

Performance

My first test was on a 3/16 steel plate, a notoriously challenging material. I’ve had other hole saws struggle or even fail entirely, but the Hole Dozer cut through with surprising ease. The 3.5 TPI tooth design meant that each pass was smooth and efficient, with minimal resistance. I was able to cut multiple holes without having to replace the bit, a testament to its durability and edge retention.

Switching to wood, the Hole Dozer continued to impress. Whether it was hardwood or softwood, the saw made clean, smooth cuts without overheating. The all-access slot design for easy plug removal is a thoughtful addition, saving time and frustration when dealing with stubborn plugs. The pilot visibility is excellent, allowing for accurate placement and reducing the likelihood of mistakes.

Versatility

The Hole Dozer truly shines in its versatility. I tested it on various materials, including metal, wood, plastic, and even fiberglass. In each case, it performed admirably. For example, drilling into a stainless steel box was a breeze. After 15 holes, the bit was still sharp and ready for more, a level of performance that is rare in many hole saws.

However, it’s important to note that the Hole Dozer is not suitable for all materials. When I attempted to use it on a concrete block wall, the teeth were completely worn down within seconds. This highlights the need to choose the right tool for the job and be aware of the material limitations.

Ease of Use

One of the most significant advantages of the Hole Dozer is its user-friendly design. The included arbor makes setup straightforward, and the hex shank ensures a secure fit in the drill. The saw is optimized for cordless tools, which is a boon for those who prefer the convenience and portability of battery-powered drills. The cutting depth of 1.62 inches is more than adequate for most applications, and the saw’s lightweight design (just 0.43 lbs) means it’s easy to handle and maneuver.

Drawbacks

While the Hole Dozer excels in many areas, it’s not without its flaws. Some users may find that it dulls quickly, especially when used on harder materials like cement board siding. In my experience, the saw struggled a bit when transitioning from cement board to OSB, suggesting that it may not be the best choice for such applications. Additionally, the pilot bit may not always center perfectly, which could lead to issues with precision.

Final Thoughts

Overall, the Milwaukee Hole Dozer Bi-Metal Hole Saw is a formidable tool that delivers on its promises. Its durability, efficiency, and versatility make it a valuable addition to any toolbox. Whether you’re a professional tradesperson or a DIY enthusiast, this hole saw is likely to meet your needs and then some.

I would recommend the Hole Dozer for anyone looking for a reliable, high-performing hole saw. Its ability to cut through a wide range of materials with ease, coupled with its thoughtful design features, makes it a standout choice. However, it’s essential to be mindful of its limitations and ensure you’re using the right tool for the job. For those dealing with concrete or other extremely hard materials, a different tool might be more appropriate. But for general-purpose use, the Hole Dozer is hard to beat.
