Find the Right Twist Drill Bits for the Job

Twist drill bits are among the most common drill bit types for everyday use. These metal drill bits are usually made from high-speed steel (hss) so you can use them for cutting metal. Twist drill bits are available in a wide range of sizes, so you have options that enable you to complete a variety of projects. If you need wood drill bits to work on a woodworking project, twist drill bits are a great option. New bits are good for woodworking projects, but after you use them to cut metal, they might be too dull for wood.


Twist drill bit sets feature bits in various sizes, with options that’ll drill holes in materials from metal and wood to plastic and concrete. Two-flute drill bits have two spirals, or flutes, around the rod and are good for drilling a small primary hole. To increase the size of the hole, follow up with a three- or four-flute drill bit in a larger diameter, as necessary.


There are many types of drill bits to choose from, based on the project you’re working on. Countersink drill bits, for example, are specialty bits designed for drilling into wood. They can create pilot, countersink and counterbore holes in a single action, so you can countersink a fastener and install a plug over a fastener head. If you’re working with tile, opt for a tile drill bit which can drill into some types of tile while reducing cracks. Installing hinges to a door or cabinets? Consider a self-centering drill bit which is designed to drill a precise centered hole each time it drills.

Twist drill bits range in size from 1/64 inch to 2-1/2 inches in diameter. Sharp twist drill bits for metal can produce minimal heat buildup and friction. Have a broken bolt or screw? Then a left-handed twist drill bit, which turns counterclockwise, will help you extract the broken fastener. For more information, see our Drill Bits Buying Guide.
