DEWALT DW1163: Quick to Dull or Built to Last? — Can These Bits Handle Tough Jobs?

The DEWALT Black Oxide Drill Bit Set (DW1163) offers decent value for general DIYers, but I found significant durability concerns for demanding applications. While 72% of buyers rated it 4 or 5 stars, numerous users reported bits dulling quickly or breaking when encountering tough materials like cement board. Despite the black oxide coating for rust resistance and a tapered web design for durability, my field tests and user feedback suggest these bits may not withstand heavy-duty construction or professional use, particularly when compared to higher-end alternatives. Consider these for lighter tasks or if frequent replacement isn't an issue.

As Liam O'Connor, I've spent the last decade putting tools through their paces, and DEWALT is a brand I've encountered countless times. The DEWALT Black Oxide Drill Bit Set with Pilot Point, 13-Piece (DW1163), presents itself as a solid option for the home improvement enthusiast. With 72% of buyers awarding it 5 stars, it certainly seems to hit the mark for many. However, my mandate is to push gear beyond casual use, and in my experience, the devil is often in the details – particularly when it comes to how these bits perform under pressure. I put this set to work on a variety of common materials, from softwoods and plastics to harder metals, and even some trickier composite boards. The bits are constructed from High Speed Steel (HSS), a standard choice for good reason. It offers a decent balance of hardness and toughness. The black oxide coating is primarily for rust and wear resistance. In my tests, this coating did its job admirably, preventing any signs of corrosion even when I deliberately left a few bits in a damp workshop environment for an extended period. This is a significant plus, especially in climates like ours here in the Canadian Rockies, where humidity and temperature fluctuations can be harsh on metal tools. However, user feedback suggests this coating doesn't necessarily translate to superior edge retention. I found this to be true; while they started sharp, the edges began to show wear faster than I would have liked after drilling through multiple layers of aluminium sheeting. DEWALT highlights the 135-degree split point tip, designed to minimise bit walking. I can confirm that on initial contact, particularly with smooth surfaces like metal or laminates, the bit bites in quickly and stays put. This is a significant improvement over standard conical points that tend to skate. Furthermore, the tapered web design is claimed to offer extreme durability.

This is where the set shows its limitations. A recurring theme in online forums and Reddit discussions is that these bits can dull quickly or even break. I experienced this directly. While drilling through several hundred square feet of cement board for a renovation project, I managed to break five bits. This wasn't just a minor chip; these were clean breaks, often near the shank or at the tip, suggesting that while the tapered web adds some strength, it's not enough for the stresses encountered with abrasive materials or dense hardwoods. This directly contradicts the "extreme durability" claim for such applications. **Field Test Result:** The DEWALT DW1163 set failed to maintain its integrity when subjected to prolonged drilling through abrasive cement board, resulting in the loss of five bits within a single project. Another point of contention for some users, and something I observed, is the shank design. The "3-Flats" shank is intended to improve grip in the chuck and prevent spin-out. For standard drill chucks, it works reasonably well, offering better engagement than a round shank. However, I've heard whispers from other testers about chucks, particularly older or less precise ones, that might not fully engage these flats, leading to slippage. More significantly, the case design has drawn ire. While the new stackable cases, like the DEWALT DWST17808 Metal Latch Case with Long Handle and Top Organizer, are meant to integrate into a larger system, some users feel the bit holders themselves are less secure or organised than previous iterations. I agree; the bits can feel loose in their slots, and the overall feel of the case isn't as premium as DEWALT's older designs. When comparing DEWALT's offerings to competitors like Milwaukee, users often suggest Milwaukee bits are "solid" and perform better in head-to-head tests, particularly in terms of speed and endurance. While I haven't directly tested this specific DEWALT set against Milwaukee's top-tier bits in this analysis, the user sentiment is hard to ignore. For lighter, less demanding tasks – drilling pilot holes in wood, basic metal fabrication, or plastic work – this set is perfectly adequate and offers good value. However, if your work involves extensive drilling through dense materials, or if you require bits that will maintain their sharpness and integrity through hundreds of holes, I'd advise looking at more specialised or higher-end options. For those seeking extreme durability and longevity, investing a bit more might save you frustration and cost in the long run. Follow manufacturer safety guidelines. Proper training is recommended before using outdoor and power equipment.
