A twist drill is used most commonly for drilling through metal. Twist drills often have two cutting edges and two flutes to remove chips as the hole is cut.
Twist drills are sometimes known as Morse drills in an industrial setting. While these drills have tips designed to cut through metal, they can also be used for wood applications. The drills come in a wide range of sizes depending on the use. They are also compatible with different sizes of bits and tips. Twist drills are sometimes designed to run at higher speeds in order to penetrate strong types of metal materials.
