AUGER center-spurred spiral wood drill bit with side spur is meant for drilling wood. Thanks to the coarse-threaded tip, it drills super fast through all types of wood. The single-threaded bit makes the drill hole smoother. The extra-wide blade clears out drilling chips efficiently. The bit is hardened all the way along, which boosts its durability. The hexagonal shank stops the bit from spinning in the chuck. Coarse-threaded bit Single-threaded bit Fully hardened Hexagonal shank Handy plastic hanging case
