Milwaukee 2-1/2" Diamond Plus™ Hole Saw

The Milwaukee 2-1/2" Diamond Plus™ Hole Saw is a versatile and robust tool designed for cutting through some of the toughest materials, including tile, stone, and glass. In my experience, this hole saw stands out due to its superior build quality and efficiency, making it a valuable addition to any toolkit, whether for professional use or DIY projects.

Durability and Performance

One of the most impressive features of this hole saw is its durability. Milwaukee claims that it has up to 10 times longer life than standard hole saws, and my usage supports this claim. The higher-grade diamonds and enhanced braze used in the construction significantly contribute to its longevity. I used this hole saw to drill multiple holes in porcelain tiles, and it maintained its sharpness and efficiency throughout the process. The diamond retention is superb, even when cutting through hard materials, which is a testament to its high-quality construction.

Ease of Use

Using the Milwaukee Diamond Plus Hole Saw is straightforward, even for those who might not have extensive experience with diamond hole saws. The large slot geometry is particularly beneficial for easy plug removal, which can often be a tedious task with other hole saws. Starting the hole can be a bit tricky, especially on slick surfaces like tiles. However, following the recommended technique of starting at a 45-degree angle and gradually bringing it to 90 degrees works well. This method helps in avoiding the bit from skipping on the surface, ensuring a more accurate start.

Versatility

The versatility of this hole saw is another significant advantage. I utilized it for various materials, including ceramic tiles, porcelain, and even glass. Each time, the cuts were clean and precise, with no visible chipping or cracking. This versatility makes it an excellent choice for a wide range of applications, from installing fixtures in a bathroom to setting up paver lighting outdoors. The tool handled each task with ease, proving its capability across different materials.

Cooling and Maintenance

One crucial aspect to keep in mind while using this hole saw is the need for proper cooling. Overheating can reduce the life of the tool and affect its performance. I found that using water as a coolant significantly improved the cutting process and maintained the integrity of the tool. A simple spray bottle or a gentle stream of water while drilling was sufficient to keep the tool cool and functioning optimally. Additionally, keeping a steady, gentle pressure and not forcing the tool through the material also helped in achieving better results and extending the tool’s life.

Practical Tips

Based on my experience, here are a few practical tips for getting the best out of the Milwaukee Diamond Plus Hole Saw:

1. Use a Guide: When drilling through particularly hard or smooth surfaces, using a guide can help in keeping the hole saw steady and prevent it from drifting.

2. Slow and Steady: Applying slow speed and gentle pressure helps in making clean cuts and reduces the risk of overheating.

3. Cooling is Key: Always use water or another coolant to keep the tool from overheating. This not only improves performance but also extends the tool’s lifespan.

4. Start at an Angle: Beginning the cut at a 45-degree angle and then bringing it to 90 degrees can help in making a more accurate start and prevent the bit from skipping.

Room for Improvement

While the Milwaukee Diamond Plus Hole Saw excels in many areas, there are a couple of minor drawbacks. The initial cut can be challenging to start accurately without a guide, especially for beginners. Additionally, removing the cut plug from the bit can sometimes be tricky. However, these issues are relatively minor and can be mitigated with a bit of practice and the right techniques.

Final Thoughts

Overall, the Milwaukee 2-1/2" Diamond Plus™ Hole Saw is an exceptional tool that delivers on its promises of durability, performance, and versatility. Its ability to handle various materials with ease, coupled with its robust build quality, makes it a worthwhile investment for both professionals and DIY enthusiasts.

I would highly recommend this tool to anyone needing a reliable and efficient hole saw for cutting through tough materials like tile, stone, and glass. The minor challenges, such as starting the cut and plug removal, are easily manageable with the right approach and do not significantly detract from the tool’s overall performance and value. Milwaukee has once again proven why it is a trusted name in the industry, and this hole saw is a prime example of their commitment to quality and innovation.
