Metalworking drill bits are designed to cut a wide range of metals, including steel, aluminum, and copper. Choosing the right metalworking bit depends on the material being cut and the desired depth and diameter of the hole. High speed steel is a standard drill bit material and offers good rigidity. For drilling tougher, harder materials, carbide drill bits are commonly used. In addition to cutter material, bit length, flute design, and point style are also important considerations and depend on the specific task.
