The AUGER center-spur spiral wood drill bit with side spur is made for drilling wood. Thanks to its coarse-threaded tip, it drills through all types of wood super fast. The single-flute bit makes the hole smoother. The extra-wide blade clears out the drilling chips really well. 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-flute bit Fully hardened Hex shank Handy plastic hanging case
