DeWalt 7/8 in. - 1-1/8 in. Impact Ready Titanium Nitride Coating Step Drill Bit Set

Investing in quality tools is crucial for any tradesperson or DIY enthusiast. One tool that has significantly impressed me is the DeWalt Impact Ready Titanium Nitride Coating Step Drill Bit Set, model DWA1789IR. This step drill bit set stands out due to its design, durability, and overall performance.

The first thing you notice about this DeWalt step drill bit set is its robust build quality. The titanium nitride coating is not just a fancy term; it genuinely adds to the durability of the bit. Compared to standard drill bits, these stay sharper longer and resist wear and tear remarkably well. This coating also reduces friction, which translates to smoother and faster drilling.

One of the key features that I appreciated is the dual flute spiral design. This design enhances chip removal, ensuring that the bit doesn't get clogged up with debris, which can be a common issue with other bits. The result is a cleaner hole and a more efficient drilling process. Whether you're working on metal, wood, or plastic, the dual flute spiral design ensures that you get a precise and clean cut every time.

The split point tips also deserve a mention. These tips allow for high-speed drilling and reduce the need for a pilot hole. This feature saves a lot of time, especially when you're working on multiple holes. The bit starts cutting immediately upon contact, which reduces the chances of the bit wandering off the mark.

Another practical aspect of this tool is the laser-engraved numbers on the step sizes. This might seem like a minor detail, but it significantly improves visibility and ensures that you always know which size you're drilling. This feature is particularly useful in dimly lit work environments or when you're in a hurry.

The 1/4 inch hex shank is designed for compatibility with both impact drivers and drills, making this tool incredibly versatile. I tested it with both my impact driver and my corded drill, and it performed exceptionally well with both. The hex shank ensures a secure fit, reducing the chances of slippage and improving overall control.

However, it's worth noting that using an extension with this bit can lead to issues. In one instance, I tried using an extension with my impact driver, and unfortunately, the 1/4 inch chuck adapter snapped off. This was quite surprising considering the overall quality of the tool and its price point. It’s a reminder that while the bit itself is durable, the accessories you pair with it should also be of high quality.

When it comes to performance, this step drill bit excels. I tested it on various materials, including 18-gauge stainless steel and 1/4 inch cast iron. The bit cut through these materials with ease, almost like slicing through butter. Using a Milwaukee battery hand drill, I drilled multiple holes without any visible signs of wear on the bit. Even after extended use, the bit remained sharp and effective.

One of the most impressive aspects of this DeWalt step drill bit is its ability to maintain its sharpness over time. As a contractor, I have used many step bits from different brands, but this one has stayed sharp the longest. This edge retention is crucial, especially when you're working on tough materials that can quickly dull inferior bits.

Despite its high performance, it’s important to manage your expectations regarding the cost. This bit set is not cheap, and some might find it adds a significant expense to their toolkit. However, considering its durability and performance, I believe it's a worthwhile investment. You might find it slightly cheaper online than in retail shops, which can help mitigate the cost.

I also appreciate the convenience this tool offers. I carry these bits in my tool bag along with my 1/4 inch driver, which means I don't need to lug around a separate drill. This reduces the weight and bulk of my toolkit, making it easier to move around job sites.

To sum up, the DeWalt Impact Ready Titanium Nitride Coating Step Drill Bit Set is a fantastic addition to any toolkit. Its durability, performance, and practical features make it stand out from the competition. The dual flute spiral design, split point tips, and laser-engraved numbers all contribute to a superior drilling experience. While it’s important to be cautious with extensions and consider the cost, the overall benefits far outweigh these minor drawbacks.

I would highly recommend this step drill bit set to both professionals and DIY enthusiasts. Its ability to maintain sharpness, coupled with the high-speed drilling and clean cuts, makes it a reliable and efficient tool for a wide range of applications. Investing in this DeWalt step drill bit set is a decision you won't regret.
