Milwaukee 7/8" Hole Dozer Bi-Metal Hole Saw

Cutting clean, precise holes in various materials can be a challenging task, but the Milwaukee 7/8" Hole Dozer Bi-Metal Hole Saw makes it an effortless experience. As someone who frequently works on both metal and wood projects, I was eager to put this hole saw to the test. What I found was a tool that not only met my expectations but significantly exceeded them.

Design and Build Quality

Upon first inspection, the Hole Dozer has a robust and sturdy feel. It's evident that Milwaukee put considerable thought into its design. The bi-metal construction suggests durability and longevity, which is crucial for a tool that's going to see heavy use. The 3.5 TPI (teeth per inch) tooth design is optimized for cutting through metal, but it also handles wood, plastic, and other materials with ease.

One of the standout features is the "All Access Slots" that make plug removal a breeze. This is a significant time-saver, especially when you're cutting multiple holes in succession. The increased pilot visibility is another thoughtful addition, allowing for accurate placement every time. I found this particularly useful when drilling into delicate or expensive materials where precision is paramount.

Performance

The performance of the Hole Dozer is where it truly shines. I used it first on a piece of 1-inch hardwood flooring, and it cut through like a hot knife through butter. There was no jumping or wandering; the hole saw started cutting exactly where I placed it and maintained a straight path throughout. The thermoset coating reduces friction and drag, which not only makes the cutting process smoother but also extends the life of the tool.

Switching over to metal, I tested the Hole Dozer on a piece of mild steel. Again, the performance was impressive. The saw maintained its sharpness even after several cuts, and there was minimal wear on the teeth. Milwaukee's Limited Lifetime Tooth Break Warranty adds an extra layer of confidence, though I doubt I'll need to use it anytime soon given the tool's durability.

Versatility

One of the most appealing aspects of the Hole Dozer is its versatility. Whether you're working on electrical installations, plumbing, or general carpentry, this tool is up to the task. I used it to cut holes for a new washer circuit in a client's house, and it handled the multi-layered wall (sheetrock and two layers of wood) effortlessly. The clean cuts and minimal marking were a pleasant surprise.

I also tried the Hole Dozer on some PVC piping for a plumbing project. The cuts were clean and precise, with no chipping or rough edges. This level of versatility makes the Hole Dozer a valuable addition to any toolbox, whether you're a professional contractor or a DIY enthusiast.

Ease of Use

Setting up the Hole Dozer is straightforward. The arbor system is user-friendly, and the saws can be swapped out quickly when needed. This is particularly useful when you're working on a project that requires multiple hole sizes. The tool's design ensures that the arbor doesn't get jammed, a common issue with other hole saws I've used in the past.

The ease of plug removal is another highlight. After cutting through several pieces of wood and metal, I found that removing the plugs was quick and painless, thanks to the strategically placed access slots. This feature alone can save a significant amount of time and frustration, especially on larger projects.

Durability

Durability is a critical factor for any tool, and the Hole Dozer doesn't disappoint. The bi-metal construction and thermoset coating contribute to its longevity. Even after extensive use, the teeth showed minimal signs of wear. The tool's ability to maintain its sharpness over multiple cuts is a testament to its quality.

I also appreciate the Limited Lifetime Tooth Break Warranty. While I haven't had any issues so far, it's reassuring to know that Milwaukee stands behind their product. This warranty is a clear indication of the company's confidence in the Hole Dozer's durability and performance.

Limitations

No tool is without its limitations, and the Hole Dozer is no exception. While it excels in cutting wood, metal, and plastic, it's not suitable for harder materials like stone, stucco, or concrete. For these applications, a carbide version would be more appropriate. However, for general-purpose use, the Hole Dozer is more than capable.

Another minor drawback is the ruggedness of the teeth. While they cut through most materials with ease, they can get caught and jump when notching tubing. This can result in a less clean cut on the backside of the wood. It's a small issue, but it's worth noting if you're working on projects that require exceptionally clean finishes.

Conclusion

In summary, the Milwaukee 7/8" Hole Dozer Bi-Metal Hole Saw is a versatile, durable, and high-performing tool that excels in various applications. Its thoughtful design features, such as the All Access Slots and increased pilot visibility, make it user-friendly and efficient. The tool's ability to maintain its sharpness and cut cleanly through multiple materials is impressive.

While it has some limitations, particularly with harder materials, these are minor compared to its overall performance and versatility. The Limited Lifetime Tooth Break Warranty adds an extra layer of confidence, making it a worthwhile investment.

I highly recommend the Milwaukee Hole Dozer for anyone in need of a reliable and efficient hole saw. Whether you're a professional contractor or a DIY enthusiast, this tool will make your projects easier and more enjoyable.
