WoodOwl 07831 Ultra Smooth Double Cut

The WoodOwl 07831 is a 24-inch auger bit with a 1-1/16-inch diameter designed for demanding woodworkers. Its double-flute, double-cut design drills clean, circular holes quickly in deep-boring applications. It suits timber framers, pole barn builders, lineworkers and arborists who need extended reach without sacrificing accuracy. The proprietary high-carbon steel construction reduces user fatigue and lessens strain on the tool motor or battery.

7/16 quick-change shank installation

The 7/16 quick-change shank fits compatible drill chucks and quick-change adapters for fast bit swaps. Ensure the shank seats fully and locks securely before starting the motor to prevent wobble. A loose or partially engaged shank is the most common cause of off-centre holes and excessive vibration. Clean debris from the shank and chuck jaws regularly to maintain a solid connection during deep drilling.

Check chuck compatibility and workpiece thickness

Verify that your drill accepts a 7/16-inch quick-change shank before ordering. The 24-inch overall length requires a workpiece thick enough to accommodate the full bit length or a through-hole application. Confirm the tool provides sufficient torque for a 1-1/16-inch diameter cutter in dense timber. This product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How do I know the 24" Ultra Smooth Double Cut bit is drilling true after setup?

The balanced, wobble-free design keeps the bit tracking straight; a clean, circular hole with minimal vibration confirms it is working as intended.

What comes in the box and what must I supply for the 7/16 quick-change shank?

The package contains the 24" x 1-1/16" auger bit only; you need a compatible drill or impact driver with a 7/16" quick-change chuck.

When should I choose the 24" length over a shorter Ultra Smooth Duo bit?

Select the 24" overall length when you need to bore deep through thick timbers, poles or logs that shorter bits cannot reach.
