MAKITA D-07456 Single Spur Wood Auger Drill Bit, Round Shank, 12x400 mm

MAKITA D-07456 Wood Drill Bit, Single Spur Auger, Round Shank, Size 12x400 mm.
This high-quality drill bit from MAKITA, model D-07456, is designed for drilling medium-sized (12 mm) and very deep holes (400 mm total length) in softwoods and hardwoods. The drill head features a screw tip that acts as a center guide and pulls the bit into the wood, enabling fast and effortless drilling without requiring heavy downward pressure, a key characteristic of an auger bit. Additionally, its single spur design—featuring a sharp spur on only one side of the cutting edge—helps cut wood fibers at the hole perimeter, resulting in cleaner and neater holes than standard twist bits. The large single flute allows large wood chips to be evacuated efficiently and continuously, reducing clogging. Manufactured from high-quality steel, it features a round shank compatible with standard drill chucks.
