Ryobi 12 in. Diamond Grit Impact Drive Bits

Diamond grit coatings on drive bits promise enhanced durability and superior grip, which can be game-changers for anyone frequently using drills and impact drivers. The Ryobi 12 in. Diamond Grit Impact Drive Bits, model A961203, offer this very promise. But how do they perform in real-world applications?

First, let’s talk about the diamond grit coating itself. This set includes various bit types, but only the Phillips head bits come with the diamond grit coating. The coating is designed to reduce the stripping of screws by offering a significantly better grip. In my experience, this coating indeed provides better holding power, which is especially beneficial when working with Phillips head screws. The bits can hold a screw upside down without it falling off, which is quite impressive. This increased grip makes driving screws a smoother process, reducing the common issue of the bit camming out of the screw head.

However, there’s a caveat. Despite the diamond grit’s promise of a longer lifespan and superior grip, the performance can be inconsistent. During my first project, which involved hanging a gate with Phillips head screws, I encountered a significant problem. The bit tip stripped by the third hinge screw, and in another instance, the tip of the bit broke off inside the screw head. This happened using both an impact driver and a compact drill, suggesting that the problem wasn’t due to the tools but the bits themselves. Such failures are alarming, especially when they occur in a brand like Ryobi, which is known for its reliability.

The set comes in a well-designed clear cover case, which keeps the bits organized and accessible. The case includes a reversible belt clip, allowing for easy storage and mobility, particularly useful if you’re moving around a lot on a job site. The case's rotating bit holder is a convenient feature, though it initially felt tight and required some effort to rotate. A bit of silicon lube can help ease this issue, making access to the bits smoother.

Despite the innovative diamond grit coating on the Phillips bits, the other bits in the set are standard impact bits. This distinction might be slightly misleading if you expect all bits to feature the diamond coating. The lack of this coating on other bit types is a missed opportunity, as a similar enhancement could benefit them as well.

The bits’ actual performance varied significantly. For instance, the Phillips head bits showed enhanced grip but also suffered from premature wear and breakage. On the other hand, the other bits in the set, like the Torx and square drive bits, performed well without the diamond coating. They handled tasks like assembling shelves and driving screws into 2x4s without significant issues.

Durability is a crucial factor for any tool, and while the diamond grit coating theoretically extends the lifespan of the bits, the actual experience tells a mixed story. Some bits, particularly the diamond-coated Phillips ones, didn’t live up to the 20x longer life claim. They wore out quickly and failed under relatively standard usage conditions. Conversely, the non-coated bits seemed to hold up better, which is somewhat puzzling given the touted benefits of the diamond coating.

One notable mention is the variety within the set. It includes multiple sizes of Phillips, Torx, square, and slotted bits, catering to a broad range of applications. Having two of the more commonly used bits like the PH2 Phillips, SQ2 square drive, SL8 slotted, and T20 Torx is a thoughtful inclusion, ensuring you have backups for the most frequently used bits. This variety means you can tackle different projects without needing to switch out bit sets frequently, adding a layer of convenience.

The price point also plays a role in the overall value of this set. Given that it’s competitively priced, especially when found on sale, it offers a reasonable solution for DIY enthusiasts and occasional users. However, if you’re a professional requiring reliable, durable bits for daily use, the inconsistent performance and durability issues might be a deal-breaker.

In conclusion, the Ryobi 12 in. Diamond Grit Impact Drive Bits offer a mixed bag of performance. The diamond grit coating provides a noticeable improvement in grip, reducing the likelihood of stripping screws, which is a significant advantage. However, the durability of the diamond-coated bits, particularly the Phillips heads, raises concerns. The set’s variety and the inclusion of a sturdy case with a belt clip are positive aspects that enhance its usability and convenience.

Would I recommend this tool? If you’re a DIY enthusiast or someone who uses these bits occasionally, the Ryobi set offers good value for money, especially when on sale. The variety of bits and the convenience of the case are definite pluses. However, if you require high durability and consistent performance for professional-grade projects, you might want to consider other options with proven track records of reliability and longevity. The inconsistent durability of the diamond-coated bits is a significant drawback that shouldn’t be overlooked.
