Milwaukee Thunderbolt Black Oxide Drill Bit Set - 15PC

Drilling is a fundamental task in many projects, whether you're a professional contractor or an avid DIY enthusiast. That's why having a reliable set of drill bits is crucial. Recently, I had the opportunity to test out the Milwaukee Thunderbolt Black Oxide Drill Bit Set, and I must say, this set stands out for several reasons.

First Impressions and Build Quality

When I first opened the Milwaukee Thunderbolt Drill Bit Set, the robust carrying case caught my eye. The case is made from durable plastic, featuring metal hinges, and has a compact design that can easily fit in any tool bag. It includes a threaded hole for attaching an optional belt clip, which, while not included, is a nice touch for those who prefer to carry their tools on the go.

Inside the case, the bits are neatly organized, though I did find them a bit tight in their slots. While this ensures they won't fall out during transport, it does require a bit of effort to pull them out, especially the smaller bits. Over time, I expect this to loosen up, but initially, it can be a minor inconvenience.

Performance and Versatility

The performance of these drill bits is where they truly shine. The Thunderbolt set includes a range of sizes from 1/16” to 3/8”, making it versatile enough for various drilling tasks. One of the standout features is the 135° split point tip. This design effectively prevents the bits from walking or wandering when starting a hole, which is a common issue with cheaper drill bits. Whether I was drilling into wood, plastic, or softer metals, the bits performed exceptionally well, providing clean and precise holes.

The black oxide coating is another noteworthy feature. It helps reduce heat build-up and provides a layer of corrosion resistance, which is especially useful when working with metals. I found that the coating also contributed to the longevity of the bits, as they remained sharp even after multiple uses.

Durability and Strength

Durability is always a concern with drill bits, especially when working with tougher materials. The Milwaukee Thunderbolt bits have a thicker core, which significantly reduces the risk of breakage. During my testing, I applied uneven pressure and drilled at various angles to see how the bits would hold up. I'm pleased to report that they did not bend or snap, even when subjected to more strenuous conditions.

For those who frequently work with harder metals, it's worth noting that these bits are not designed for drilling into hardened steel. While they can handle softer metals with ease, attempting to drill through something like a lawnmower blade will likely result in frustration. For those specific tasks, a cobalt bit set would be more appropriate.

Chip Removal and Ease of Use

Milwaukee has incorporated a parabolic flute form in these bits, which is designed to clear chips and debris efficiently. This feature works remarkably well, especially when drilling through materials like wood and plastic. The bits remained clean, and I didn't experience any clogging, which can often slow down the drilling process and reduce accuracy.

Additionally, the 3-FLAT SECURE-GRIP™ feature prevents the bits from slipping in the chuck, providing a stable and secure grip. This is particularly beneficial when using high-speed drill drivers, as it ensures consistent performance without the need to constantly readjust the bit.

Value for Money

Considering the build quality, performance, and durability, the Milwaukee Thunderbolt Drill Bit Set offers excellent value for money. While it may be slightly more expensive than some other brands, the reliability and longevity of these bits make them a worthwhile investment. The case, despite its tight bit slots, adds to the overall value by providing a secure and organized storage solution.

Final Thoughts and Recommendation

In conclusion, the Milwaukee Thunderbolt Black Oxide Drill Bit Set is a reliable and versatile choice for anyone in need of high-quality drill bits. With its well-thought-out design features, such as the 135° split point tip, thicker core, and black oxide coating, this set is built to last and perform well across various materials. The sturdy carrying case, while having a minor flaw in bit tightness, is another positive aspect that adds to the set's overall appeal.

I highly recommend the Milwaukee Thunderbolt Drill Bit Set for both professionals and DIY enthusiasts. Its durability, performance, and thoughtful design make it a valuable addition to any tool collection. Whether you're drilling into wood, plastic, or softer metals, you can rely on these bits to get the job done efficiently and accurately.
