Description

Twist drills (also commonly referred to as twist bits) are the most widely used of all drill bit types; they will cut anything from wood and plastic to steel and concrete. They are most frequently used for metal cutting, so they are generally made from M2 high-speed steel. At diameters up to about 1/2″, twist drills are not only the cheapest of all bits a woodworker could use, they offer the widest selection of sizes. Although they are designed for cutting metal, they will work quite well in wood, if sharp. This generally means that they have not been used to cut hard materials such as steel.
