A twist bit is a type of drill bit characterized by its helical flutes. These flutes, or grooves, run up the shank of the bit, resembling a twisted shape. Twist bits are primarily used for drilling holes in wood, metal, and plastic. The helical design helps remove chips from the hole as you drill. It's like a tiny screw that bores into the material. They are versatile and come in various sizes. The angle of the twist affects their performance on different materials.
