WoodOwl 07818 Ultra Smooth Double Cut

The WoodOwl 07818 Ultra Smooth Double Cut is an 18-inch auger bit with a 1-3/8-inch diameter designed for demanding woodworkers. Its double flute, double cut geometry delivers clean, circular holes quickly and efficiently. The proprietary high-carbon steel construction reduces user fatigue and lessens strain on the tool motor or battery. A 7/16 quick-change shank allows fast bit swaps on compatible drills.

Woodworkers, timber framers and pole barn builders

This bit suits woodworkers, timber framers, pole barn builders, lineworkers and arborists who need balanced, wobble-free drilling in longer lengths. Buyers requiring triple-cut performance or diameters beyond 1-3/8 inches should look at other options. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. Users sensitive to these substances may prefer alternatives without such warnings.

Quick-change shank simplifies installation

The 7/16 quick-change shank fits directly into compatible drill chucks for rapid bit changes without extra tools. Balanced manufacturing keeps the bit running true, minimising wobble that can lead to off-centre holes. Ensure the shank seats fully in the chuck to prevent slippage under load. Regular inspection of the cutting edges maintains the ultra-smooth drilling action over time.

Questions about this item

What drill chuck or shank size accepts the 7/16 quick-change shank?

The 7/16-inch quick-change shank fits standard 1/2-inch keyed or keyless chucks and most 7/16-inch hex quick-change adapters used on heavy-duty drills and impact drivers.

Will the 18-inch overall length clear deep timbers when used with a right-angle drill attachment?

At 18 inches overall the bit reaches through 16-inch stud bays and standard timber depths, and the balanced double-cut design resists wobble even when driven from a right-angle head.

How can I confirm the 1-3/8-inch diameter is cutting true after the first few holes?

Measure each hole with a caliper or gauge; a true-cut hole will read 1-3/8 inch at multiple depths and show clean, circular walls without tear-out or ovality.
