Ultra Smooth Double Cut Auger Bit

The WoodOwl 07815 is an 18 inch by 1-1/8 inch pneumatic accessory designed for drilling clean, circular holes in wood. Its double flute, double cut geometry delivers performance similar to triple cut bits while maintaining balance and wobble-free operation. The bit features a 7/16 quick-change shank for fast tool changes. It is made from proprietary high-carbon steel to reduce user fatigue and lessen strain on the tool motor or battery.

For Demanding Woodworkers And Trades

This bit suits timber framers, pole barn builders, lineworkers, and arborists who need accurate deep holes up to 18 inches in length. It is not intended for buyers who require hole diameters other than 1-1/8 inch or lengths exceeding 18 inches. Users needing a different shank configuration should look at alternative options. The design focuses specifically on wood drilling efficiency and reduced vibration.

Proprietary Steel And Quick-Change Shank

The high-carbon steel construction directly reduces fatigue during extended drilling sessions and lowers the load on the power tool motor or battery. The 7/16 quick-change shank allows rapid bit swaps without additional tools, improving workflow speed on job sites. These features combine to provide balanced, wobble-free drilling exactly where the bit is positioned.

Questions about this item

What drill chuck or shank size does the 7/16 quick-change shank require to fit?

The 7/16 inch quick-change shank fits any standard 1/2 inch drill chuck or quick-change adapter that accepts a 7/16 inch hex shank.

Will the 18 inch overall length and 1-1/8 inch diameter bit clear the frame of my older 1/2 inch cordless drill?

Yes, the 18 inch overall length and 1-1/8 inch cutting diameter are compatible with standard 1/2 inch drills, though the long bit may extend well beyond the chuck.

How can I confirm the Ultra Smooth Double Cut bit is cutting clean, circular holes as designed?

Check that the drilled hole is perfectly round with smooth walls and minimal tear-out, and that the bit runs without wobble or vibration during use.
