Milwaukee 5/8" Hole Dozer Bi-Metal Hole Saw

The first time I used the Milwaukee 5/8" Hole Dozer Bi-Metal Hole Saw, I was immediately struck by its robust construction and thoughtful design. I had a project that required drilling several holes through various materials, including wood, drywall, and some mild steel. Right out of the package, the Hole Dozer felt solid and well-engineered, which gave me a lot of confidence.

One of the standout features of this hole saw is its 3.5 TPI tooth design. This design is not just a marketing gimmick; it genuinely enhances the tool's cutting performance. When I first used it on a piece of hardwood, the teeth bit into the material smoothly and cleanly, with minimal effort on my part. The cut was precise and didn’t result in any jagged edges or splinters, which is often a problem with lower-quality hole saws.

The Hole Dozer also boasts a durable bi-metal construction. This means it combines high-speed steel teeth with a flexible steel body, allowing it to withstand the rigors of cutting through tougher materials without breaking or dulling quickly. In my experience, this durability translated into a tool that maintained its sharpness even after multiple uses. I used it extensively on a project that involved cutting through some old, nail-embedded wood, and it performed admirably without any noticeable wear.

Another notable feature is the access slots designed for easy plug removal. Anyone who has used a hole saw knows the frustration of trying to remove plugs stuck inside the saw. Milwaukee has addressed this common issue by incorporating slots that allow you to push the plug out easily with a screwdriver or punch. This simple yet effective design element saved me a lot of time and hassle, especially when I was working on repetitive tasks.

The improved visibility for placement is another feature that shouldn’t be overlooked. The Hole Dozer has markings that make it easier to see exactly where you’re cutting, which is crucial for precision work. I found this particularly useful when I was working in tight spaces where visibility was limited. The markings helped me ensure that I was drilling in the right spot without having to constantly adjust my position.

Milwaukee has also coated the Hole Dozer to reduce friction and heat buildup during use. This is a small but significant detail that enhances the tool's performance. When cutting through metal, the saw didn’t overheat, which can be a common problem with lesser tools. The reduced friction meant I could work faster and more efficiently, without having to worry about the tool warping or losing its edge.

As someone who often works on varied projects, the versatility of the Hole Dozer is a major plus. It’s designed for general-purpose applications, and I tested it on a range of materials including duct, PVC pipe, non-ferrous metals, and even some stainless steel. In almost every instance, it cut through the material with ease. The only exception was when I tried it on some particularly tough stucco; the bi-metal teeth struggled a bit, and I had to switch to a carbide version for that specific task. However, for most other materials, the Hole Dozer performed exceptionally well.

One of the biggest selling points for me is the lifetime warranty on tooth breakage. This warranty speaks volumes about Milwaukee’s confidence in their product. While I haven’t needed to use the warranty yet, it’s reassuring to know that it’s there. It adds a layer of trust and reliability to the tool, which is always a good thing in my book.

The Hole Dozer’s ease of use is another highlight. It’s straightforward to set up, and the arbor system is designed to prevent the hole saw from getting stuck. This was particularly useful when I had to switch between different sizes quickly. The tool felt balanced and didn’t "walk" or shift during use, which is crucial for maintaining accuracy.

In terms of drawbacks, there are very few. As mentioned, it’s not the best choice for extremely tough materials like stone or concrete, but for general-purpose use, it’s hard to beat. The only other minor issue I noticed was that the paint on the hole saw started to wear off after several uses, but this didn’t affect its performance in any way. It’s a cosmetic issue that I can easily overlook given the tool’s overall effectiveness.

To sum up, the Milwaukee Hole Dozer is a high-quality, versatile tool that delivers on its promises. Its durable construction, ease of use, and thoughtful design features 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 exceed your expectations. I would highly recommend the Milwaukee Hole Dozer for anyone looking for a reliable, efficient, and long-lasting hole saw. Its performance, backed by a lifetime warranty, makes it a wise investment for any project that requires precision and durability.
