WoodOwl 07812 Ultra Smooth Double Cut

The WoodOwl 07812 Ultra Smooth Double Cut is an 18-inch auger bit with a 15/16-inch diameter. It features a double flute and double cut design for fast, clean hole drilling in wood. The 7/16 quick-change shank fits compatible power tools. Proprietary high-carbon steel construction aims to reduce user fatigue and motor strain.

Woodworkers and timber framers needing long reach

This bit suits woodworkers, timber framers, pole barn builders, lineworkers and arborists who require balanced, wobble-free drilling at extended lengths up to 24 inches. It is not intended for metal, masonry or plastic materials. Buyers needing shorter bits or different diameters should consider other options. The Proposition 65 warning indicates chemical exposure risks.

Quick-change shank simplifies tool swaps

The 7/16 quick-change shank allows rapid bit changes without extra tools. Users must ensure their drill or impact driver accepts this shank size. Common issues include using the bit on unsuitable materials which dulls the cutting edges. Proper speed and steady pressure help maintain the ultra-smooth cutting performance.

Questions about this item

What drill chuck size fits the 7/16 quick-change shank on this 18" bit?

A 7/16 hex quick-change chuck or a standard three-jaw chuck opened to at least 7/16 inch will accept the shank.

Can I use the 15/16" diameter bit in a cordless drill that normally runs 1/2" auger bits?

The larger 15/16" cutting diameter needs more torque; a high-torque cordless drill with a fresh battery will handle it, but a compact driver may stall.

How do I confirm the bit is cutting true after the first few inches?

The hole should stay a clean 15/16" circle with no wobble marks and the bit should pull itself through without excessive vibration.
