Craftsman 1/8-In. Hex Shank Titanium Nitride Coating Drill Bits

Navigating the world of drill bits can be tricky, especially when you need something reliable and versatile. The Craftsman 1/8-In. Hex Shank Titanium Nitride Coating Drill Bits, model number CMAM1308, caught my eye recently, and I decided to give them a thorough test. These bits are designed to tackle wood, plastic, and metal, making them a handy addition to any toolbox. Here's an in-depth look at how they performed during my hands-on experience.

First off, the titanium nitride coating on these drill bits is a standout feature. This coating is known for its corrosion-resistant properties, which should theoretically extend the life of the bits. In practice, I found that the coating did indeed keep the bits looking fresh and free from rust, even after several uses. This is particularly beneficial if you're working in a humid environment or if your tools are stored in less-than-ideal conditions.

The split point design of these bits is another feature worth mentioning. It’s designed to prevent the bit from wandering when you start drilling, ensuring precise hole placement. During my tests, this feature worked as advertised. The bits started cleanly and didn't drift, even when I wasn't using a pilot hole. This precision is crucial for tasks where accuracy is paramount, such as cabinetry or detailed woodworking projects.

Compatibility is also a strong suit for these bits. They fit seamlessly into any 1/4-in. hex shank, which makes them incredibly versatile. I used them with both my cordless drill and an impact driver, and they worked flawlessly with both tools. This flexibility is a huge plus, as it means you don't have to switch bits depending on the tool you're using; one size fits all.

However, not everything about these bits is perfect. Durability is a bit of a mixed bag. While the titanium nitride coating prevents corrosion, the bits themselves are somewhat prone to breaking, especially under heavy use. I experienced a couple of instances where the bits snapped while drilling through hardwood. This was particularly frustrating because it interrupted my workflow and required me to switch to a backup bit. It's worth noting that these bits are small in diameter, which naturally makes them more fragile, but it's still a downside worth considering.

One aspect that could be improved is the availability of different lengths and sizes. The 1/8-inch size is commonly used and frequently needed, but having options for longer lengths or intermediate sizes like 5/32-inch would make this set even more versatile. As it stands, the set is somewhat limited in its applications.

The bits also have a tendency to come loose in the chuck, especially when drilling into tougher materials like hardwood. This can be quite annoying and potentially dangerous, as a loose bit can cause the drill to slip or the bit to break. It's something to be mindful of, especially if you're working on a project that requires a lot of precision.

Despite these drawbacks, there are several positives that make these bits worth considering. For one, they are quite affordable, making it easy to keep a few spares on hand without breaking the bank. This is particularly useful given their tendency to break; having a backup means you can quickly swap out a broken bit and keep working without too much downtime.

Additionally, these bits fit perfectly into the Craftsman Speed-Lok lineup, which is a nice touch if you're already invested in Craftsman tools. The compatibility across the brand's range of tools adds a layer of convenience that can't be overlooked.

In terms of performance, these bits excel at drilling through wood and plastic. They cut cleanly and efficiently, making quick work of even the tougher materials. Just be cautious not to apply too much lateral pressure, as this can cause the bits to snap. For metal, they perform adequately, but I would recommend using a bit specifically designed for metal if you're working with thicker or harder metals.

To sum up, the Craftsman 1/8-In. Hex Shank Titanium Nitride Coating Drill Bits have their strengths and weaknesses. They offer excellent precision, corrosion resistance, and compatibility with various tools, making them a versatile choice for many DIY projects. However, their durability leaves something to be desired, especially when used on tougher materials.

Would I recommend these drill bits? Yes, but with reservations. If you're looking for a set of bits that are affordable and versatile for light to medium-duty tasks, these are a solid choice. Just be prepared to replace them more frequently if you're working with harder materials or require heavy-duty performance. For professional use or more demanding projects, you might want to invest in a more robust set of drill bits.
