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