Milwaukee 1-1/2" Thin Wall Hole Saw

As a seasoned tool enthusiast, I always keep an eye out for innovative solutions that can make my job easier. The Milwaukee 1-1/2" Thin Wall Hole Saw has been a recent addition to my collection, and I've put it through its paces in various scenarios. Here's my comprehensive take on how it performs and whether it's worth adding to your toolbox.

Design and Build Quality

At first glance, the Milwaukee Thin Wall Hole Saw impresses with its robust build and thoughtful design. The 1/4 inch quick change hex shank is a standout feature, making it compatible with impact drivers and ensuring swift bit changes. This is particularly advantageous when working on multiple projects where time and efficiency are of the essence.

The thin wall and 8 TPI (teeth per inch) design are intended to provide faster cuts compared to standard bi-metal hole saws. The hole saw also features a stop shoulder design to prevent over-drilling and potential damage to your components. This feature alone significantly enhances the tool's safety and precision, making it a reliable choice for various materials.

Performance

I tested this hole saw on a range of materials, including plastics, thin gauge metals, and even a 55-gallon water drum. The results were consistently impressive. The thin-wall design indeed lived up to its promise of faster cuts. When used with an impact driver, the saw breezed through thin gauge metals up to 1/8 inch thick with minimal effort. However, I found that using a regular drill/driver produced cleaner and more precise holes, especially in more delicate applications where the impact driver's torque could cause slight irregularities.

The ejection spring is another noteworthy feature. It effectively helps in the automatic removal of slugs, which can be a real time-saver. While not perfect, it certainly aids in keeping the workflow smooth and uninterrupted.

User Experience

One of the most appreciated aspects of this tool is its ease of use. The quick change hex shank allows for seamless bit changes, which is a boon when working on complex projects requiring multiple hole sizes. Furthermore, the stop shoulder design eliminates the risk of over-drilling, adding an extra layer of confidence while using the tool.

The hole saw also excels in terms of precision. Cutting through a 55-gallon plastic drum was a breeze, and the edges were smooth enough that no additional sanding was required. This level of precision is invaluable, especially when working on projects where the aesthetic finish is crucial.

Durability

Durability is always a concern with any cutting tool, and the Milwaukee Thin Wall Hole Saw does not disappoint. Despite heavy usage, the saw's teeth remained sharp, and the overall build showed no signs of wear and tear. This speaks volumes about the craftsmanship and quality materials used in its construction.

However, it's worth noting that while the tool performs exceptionally well with thin gauge metals and plastics, it may not be the best choice for more demanding materials like 18 gauge stainless steel. In one instance, the pilot drill bit broke off while attempting to penetrate a stainless steel kitchen sink. This suggests that while the tool is versatile, it's essential to match it with appropriate materials to prevent damage and ensure longevity.

Versatility

The Milwaukee Thin Wall Hole Saw shines in its versatility. Whether you're cutting through military ammo cans, vinyl, or plastic drums, this tool adapts well to various materials. The shoulder stop design is particularly beneficial for applications where precision is paramount, such as installing closet door knobs or drilling wiring panels.

However, it's important to recognize its limitations. The tool is not designed for boring holes at an angle or for deeper bores beyond its blade length. For such applications, a regular hole saw might be more appropriate.

Final Thoughts

In conclusion, the Milwaukee 1-1/2" Thin Wall Hole Saw is a high-quality, versatile tool that delivers on its promises. Its design features, such as the quick change hex shank, stop shoulder, and ejection spring, make it a reliable and efficient addition to any toolbox. While it excels in cutting thin gauge metals and plastics, it's crucial to use it within its intended material range to avoid potential issues.

Would I recommend this tool? Absolutely. Its precision, ease of use, and robust build quality make it a valuable asset for both professional tradespeople and DIY enthusiasts. Just be mindful of its limitations and ensure you're using it for the right materials to get the best results. Overall, the Milwaukee Thin Wall Hole Saw is a worthy investment that can save you time and effort on a variety of projects.
