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