Milwaukee Annular Cutter Set - 6PC

Cutting through metal can be a demanding task, requiring precision, durability, and efficiency from your tools. The Milwaukee Annular Cutter Set, model 49-22-8400, is designed to meet these demands with its six-piece assortment of high-speed steel cutters. As a tool enthusiast and regular user of various metal-cutting tools, I had the opportunity to put this set to the test, and the results were largely positive, with a few caveats worth mentioning.

Unboxing and First Impressions

Upon unboxing the Milwaukee Annular Cutter Set, I was immediately struck by the robust construction of the cutters themselves. The brand's reputation for durability is evident in the high-speed steel construction, which features three distinct hardness zones. This is designed to extend the life of each cutter, reducing the frequency of replacements or resharpening. The kit includes six sizes—9/16", 5/8", 11/16", 13/16", 15/16", and 1-1/16"—alongside an ejector pin and a 1" pilot bit, all housed in a reasonably compact carrying case.

However, the case itself left something to be desired. It felt somewhat flimsy, and the cutters did not stay securely in place during transport. This was easily remedied by adding some cushioning, but it’s a small oversight that detracts from the overall quality of the set.

Performance and Efficiency

When it comes to cutting performance, the Milwaukee Annular Cutter Set excels. The dual alternating tooth geometry facilitates improved chip ejection, which is crucial for maintaining a clean and efficient cut. I tested the 5/8" and 11/16" cutters on a variety of materials, including 1/4" copper plates and 3/8" mild steel plates. Both cutters performed admirably, completing holes in less time compared to other brands I've used in the past.

One of the standout features is the thinner wall construction, which reduces material displacement and, consequently, the effort required to complete a cut. This is particularly noticeable when drilling through thicker materials. In my tests, each hole took around 4 minutes to complete, including the time to drill a 1/4" pilot hole, which is noticeably faster than some competing products that took over 6 minutes per cut.

Durability and Edge Retention

Durability is always a crucial factor when evaluating cutting tools, and the Milwaukee Annular Cutter Set largely delivers on this front. After completing over 200 cuts with the 5/8" and 11/16" bits, they remained remarkably sharp. This longevity is a testament to the quality of the high-speed steel used and the effectiveness of the hardness zones in preventing premature dulling.

However, it’s essential to use generous amounts of cutting fluid to keep the bits cool and to clean out the hollow pathway after each cut. Neglecting these steps can lead to quicker dulling or even breakage. I found that adhering to these maintenance practices significantly extended the life of the cutters, making them a worthwhile investment despite the initial cost.

Versatility and Compatibility

The 3/4” Weldon shank design makes this set compatible with most magnetic drill presses, adding to its versatility. I used the cutters on both portable magnetized drill presses and industrial drill presses with a 3/4” chuck, and they fit seamlessly in both. The set’s compatibility with various equipment makes it an excellent choice for professionals who may need to switch between different types of drill presses frequently.

Areas for Improvement

While the performance and durability of the cutters are impressive, there are a few areas where the Milwaukee Annular Cutter Set could improve. The carrying case, as mentioned earlier, is not up to the same standard as the cutters themselves. A more secure and padded case would be a welcome upgrade, especially for those who need to transport their tools regularly.

Another point of contention is the length of the cutters. The limited depth can be a hindrance when drilling with clamps, as it restricts how deep you can drill in a single pass. Longer cutters would provide greater flexibility for more extensive projects, allowing for deeper cuts without the need to reposition clamps or the workpiece.

Additionally, while I did not experience any breakage myself, it’s worth noting that one of the smaller cutters shattered during use. This suggests that even with careful handling and proper use of cutting fluid, there may be some variability in the quality control of these bits.

Final Thoughts

Overall, the Milwaukee Annular Cutter Set is a highly effective and durable tool for cutting through various metals. The high-speed steel construction, dual alternating tooth geometry, and thinner wall design all contribute to a superior cutting experience. The compatibility with 3/4” Weldon shanks adds versatility, making this set a valuable addition to any professional’s toolkit.

However, the carrying case and cutter length are areas that could benefit from improvement. Despite these minor drawbacks, the set’s performance and durability make it a worthwhile investment, particularly if you adhere to proper maintenance practices like using ample cutting fluid and cleaning out the hollow pathways.

Would I recommend the Milwaukee Annular Cutter Set? Absolutely. Its efficiency and longevity outweigh the relatively minor inconveniences. For anyone looking to upgrade their metal-cutting tools, this set offers a reliable and high-performing option.
