Milwaukee 17/32" S&D Black Oxide Drill Bit

Diving into the world of drill bits, the Milwaukee 17/32" S&D Black Oxide Drill Bit (model number 48-89-2739) stands out with its robust design and impressive performance features. Whether you are a seasoned professional or a DIY enthusiast, the importance of a reliable drill bit cannot be overstated. In my experience, this particular bit offers a blend of durability and precision that makes it a worthy addition to any toolbox.

Design and Build Quality

One of the first things that caught my eye was the black oxide coating. This feature isn't just for aesthetics; it provides lubricity and resists corrosion, ensuring the bit remains in top condition even after extensive use. The 135° split point tip is another highlight. It starts on contact and prevents walking, making it ideal for drilling into a variety of materials, including metal, wood, and plastic.

The shank design is also noteworthy. The 3-Flat Secure-Grip™ shank holds the bit firmly in the drill chuck, reducing the chances of slippage. This is particularly useful when working on precision tasks where any movement could compromise the quality of the work. The reduced shank diameter allows it to fit into 1/2" chucks, which adds to its versatility.

Performance

When it comes to performance, the Milwaukee 17/32" drill bit does not disappoint. I used this bit to drill multiple holes in a 1/4 inch thick mild steel plate, and it performed admirably. The bit maintained its sharpness throughout the process, and there was no noticeable increase in effort required for the last few holes. This speaks volumes about its edge retention capabilities.

One of the standout features is the bit's ability to clear chips efficiently. The flute form is designed to remove material quickly, which prevents clogging and keeps the bit cool during extended use. This is crucial when working with metals, as excessive heat can dull the bit and reduce its lifespan.

Versatility

The Milwaukee 17/32" drill bit is versatile enough to handle a range of applications. Whether you're drilling into metal, wood, or plastic, this bit gets the job done with ease. I even used it to drill through the frame of my car to install a trailer hitch, and it worked flawlessly. The bit's ability to handle such demanding tasks without any signs of wear and tear is impressive.

Ease of Use

Ease of use is another area where this drill bit shines. The 3-Flat Secure-Grip™ shank makes it easy to secure in the chuck, and the split point tip ensures that the bit starts precisely where you want it to. This eliminates the need for a center punch and reduces the chances of the bit wandering off course.

The reduced shank diameter is a thoughtful addition, allowing the bit to be used with standard 1/2" chucks. This makes it compatible with a wide range of drills, from handheld models to more powerful drill presses. I used it with both a handheld drill and a bench-top drill press, and it performed consistently well with both.

Considerations

While the Milwaukee 17/32" drill bit excels in many areas, it's not without its drawbacks. Some users may find the bit's performance lacking when dealing with extremely hard materials. In such cases, stepping up through smaller drill bit sizes before using the 17/32" bit can help prevent seizing and ensure a smoother drilling experience.

Another point to consider is the shipping and delivery time. While this doesn't affect the quality of the bit itself, it can be an inconvenience if you need the bit quickly for a time-sensitive project. Planning ahead and ordering well in advance can help mitigate this issue.

Durability

Durability is a critical factor for any tool, and the Milwaukee 17/32" drill bit holds up well in this regard. The black oxide coating plays a significant role in protecting the bit from corrosion, while the high-quality steel construction ensures it can withstand the rigors of demanding tasks. I used this bit extensively over several projects, and it showed no signs of dulling or wear, even after drilling through tough materials like cast iron and stainless steel.

Value for Money

Considering its performance and durability, the Milwaukee 17/32" drill bit offers excellent value for money. It's priced competitively, especially when compared to other high-end drill bits on the market. The longevity and reliability of this bit mean that it's a worthwhile investment for anyone who regularly undertakes drilling tasks.

Final Thoughts

In conclusion, the Milwaukee 17/32" S&D Black Oxide Drill Bit is a well-crafted, reliable tool that excels in a variety of applications. Its design features, such as the 135° split point tip and 3-Flat Secure-Grip™ shank, make it easy to use and ensure precise, efficient drilling. The black oxide coating and durable construction further enhance its appeal, offering long-term reliability and excellent value for money.

I would highly recommend this drill bit to anyone in need of a versatile, high-performance tool. Whether you're working on metal, wood, or plastic, the Milwaukee 17/32" drill bit is up to the challenge. Just be mindful of the shipping times and consider stepping up through smaller bit sizes for extremely hard materials to get the best results.
