WoodOwl 07817 Ultra Smooth Double Cut

The WoodOwl 07817 is an 18-inch ultra smooth double cut auger bit designed for demanding woodworkers who need clean, circular holes quickly. It serves timber framers, pole barn builders, lineworkers and arborists requiring reliable deep drilling performance in wood.

1-1/4 inch diameter double flute design

The single specification that decides fit is the 1-1/4 inch diameter combined with the double flute, double cut geometry. This configuration delivers cutting efficiency similar to triple cut versions while supporting longer lengths up to 24 inches for deep boring tasks.

7/16 quick-change shank for fast swaps

Installation uses a 7/16 quick-change shank that locks into compatible drill chucks without tools, reducing downtime on site. The balanced, wobble-free construction keeps the bit tracking true, minimising user fatigue and motor strain during extended use.

Questions about this item

What does the 18 inch overall length mean when the bit is chucked into a drill?

The 18 inch overall length gives you that much reach from the chuck face, so you can bore deep through thick timbers or multiple joists without an extension.

How does the 7/16 quick-change shank limit what drills can drive this bit?

The 7/16 hex shank fits any 1/2 inch or larger chuck and quick-change adapters, but it will not seat in 3/8 inch chucks, so a half-inch drill is the minimum.

What clearance does the 1-1/4 inch diameter need in the workpiece or guide?

The bit cuts a 1-1/4 inch hole, so the entry point, any drill guide, or the cavity you are boring through must be at least that wide to avoid binding.
