Drill bits are one of the most important tools in any toolbox, but finding the right one can be difficult. It's important to consider the type of bit you need, which material you're drilling into, and the specific application. Our drills and drill bits experts test drill bits for ease of use, performance, and durability.

Drill bits come in a variety of materials, including steel, stainless steel, aluminum, copper, titanium, and tungsten carbide. The hardness of the material determines how tough it is and how well it holds up to wear and tear. Steel and stainless steel drill bits are cheaper, but they're also weaker and more likely to break.

Our tests evaluate drill bits by rating their ease of use, performance, and durability. We also look at durability, because drill bits are meant to last, so they should be tough enough to handle any job.

Twist design 135-degree split point and twist design Increases cutting speed with self-centering and prevents walking, clears chips and particles faster

This 29-piece set is a workhorse for drilling holes in a variety of materials. The bits are sharp and well-constructed. The bits have a longer shaft than other sets we tested, so they're easier to handle, and we found that the bits were easier to turn. The set comes with a sturdy carrying bag, so it's ready when you are. The bits are also easy to store and transport, and the case makes finding a specific bit easy. These bits are designed specifically for drilling into concrete, so we only tested them in this setting. The 135-degree split point bits worked best on concrete, and the set was small enough that we didn't find it heavy or cumbersome to tote around. The set also comes with two 1/4-inch locking bit drivers, which worked great for driving screws into concrete. The downside to the set is that, because the bits are short, they struggle to pass through very small holes, and with longer bits, drilling through smaller holes is easier.
