AUGER core-threaded spiral wood drill bit with side blade is meant for drilling wood. Thanks to the coarse-threaded tip, it drills fast through all wood types. The single-threaded blade makes the drill hole smoother. The extra-wide blade removes drilling chips effectively. The blade is hardened all the way, which improves its durability. The hexagonal shank prevents the blade from spinning in the chuck. Coarse-threaded blade Single-threaded blade Fully hardened Hexagonal shank Handy in a plastic hanging case
