Milwaukee 2" Carbide Grit Hole Saw

Cutting through abrasive materials like brick, cement board, and tile often requires specialized tools, and the 2" Carbide Grit Hole Saw from Milwaukee seemed like a promising choice. With a tungsten carbide grit edge and a design tailored for abrasive materials, I was eager to see how it would perform under various conditions.

My first project involved drilling holes through the brick exterior of my house. I quickly realized that patience and the right technique were crucial. Initially, I started with a slow drill speed, but this approach was painfully slow. Switching to hammer drill mode and increasing the speed significantly improved the cutting rate, albeit at the expense of the tool's longevity. Water cooling was essential to keep the bit from overheating and dulling prematurely. Despite these adjustments, the carbide edge showed noticeable wear after just a few holes, suggesting that while the hole saw is capable, it's not the most durable option for extensive brickwork.

Next, I tested the hole saw on stucco. The performance here was quite commendable. The coarse grit and segmented edge allowed for swift and efficient cutting, and after several holes, the carbide teeth showed minimal wear. This reinforced my belief that the tool is well-suited for cementitious materials, where the abrasive nature of the material doesn't excessively degrade the cutting edge.

However, the tool's packaging could be more informative. The importance of using water to cool the bit and improve cutting efficiency wasn't mentioned, which could lead to frustration for users who aren't familiar with best practices for using carbide grit hole saws. This lack of guidance might be a contributing factor to some negative experiences.

For a different test, I used the hole saw to cut through a 2-inch water meter lid. This task took about ten minutes, and water cooling proved beneficial once again. The cutting process was smooth, and the tool handled the job well. This confirmed that the hole saw could handle a variety of materials beyond just brick and stucco, including tougher composites.

One aspect that could be improved is the need for additional components. The hole saw isn't a complete unit and requires a compatible arbor, which isn't always clear to first-time users. This can lead to confusion and inconvenience, as it did for me initially. Ensuring that users are aware of all necessary components before purchase would enhance the overall experience.

While the hole saw performed admirably on several materials, it struggled with ceramic tile. Despite using water and varying the drill speed, the tool had difficulty making significant progress. This was a disappointment, especially given the high expectations set by the Milwaukee brand. In contrast, a more expensive diamond grit hole saw handled the same task with ease, highlighting a significant performance gap.

On a positive note, the hole saw excelled at cutting through cement siding. It made quick work of the material, allowing me to install attic air vents without any issues. The wide, angled, and offset slots made plug access straightforward, which is a thoughtful design feature that simplifies the process.

Durability is a mixed bag with this tool. While it holds up well for occasional use in masonry and cementitious materials, it may not be the best choice for extensive or heavy-duty projects. The carbide grit edge, while effective, does dull over time, and the tool's performance can degrade significantly with prolonged use. For everyday use in masonry, a diamond grit hole saw would likely be a more durable and efficient investment.

One of the standout features of this tool is its craftsmanship. The build quality is solid, with thick steel and heavy carbide on the cutting edges. This robust construction contributes to its performance and longevity, making it a reliable choice for a variety of tasks. However, it's important to manage expectations and understand that it's not a one-size-fits-all solution.

In conclusion, the 2" Carbide Grit Hole Saw from Milwaukee is a versatile tool that performs well in several applications, particularly with cementitious materials and occasional masonry tasks. Its tungsten carbide grit edge and thoughtful design features make it a capable and user-friendly option. However, its limitations become apparent with more demanding materials like ceramic tile and extensive brickwork. For these tougher tasks, a diamond grit hole saw might be a better choice.

I would recommend this tool for DIY enthusiasts and professionals who need a reliable hole saw for occasional use on a variety of abrasive materials. It's a cost-effective alternative to diamond grit hole saws, provided you understand its limitations and use it appropriately. Proper technique, water cooling, and managing expectations will ensure you get the best performance out of this tool. If you're planning extensive or heavy-duty projects, investing in a more durable option may save you time and frustration in the long run.
