18-inch 3/4-inch auger bit for heavy timber

This 18-inch long auger bit has a 3/4-inch cutting diameter and a 7/16-inch quick-change shank. It is built from proprietary high-carbon steel for demanding woodworkers, timber framers, pole barn builders, lineworkers and arborists. The double flute, double cut design drills clean, circular holes quickly and efficiently in long lengths up to 24 inches. Balanced construction keeps the bit wobble-free so it drills exactly where you aim.

Practical limits of the double flute design

The double flute, double cut geometry offers performance similar to a triple cut version while reaching longer lengths up to 24 inches. It is designed to reduce fatigue on the user and lessen strain on the tool motor or battery during extended drilling. The bit carries a California Proposition 65 warning for chemicals known to cause cancer and birth defects or other reproductive harm. It is not suited for buyers who need a different cutting diameter or a shorter overall length.

Quick-change shank installation and common issues

The 7/16-inch quick-change shank fits compatible chucks for fast bit swaps without extra tools. Ensure the shank seats fully to prevent wobble or slippage under load. Applying steady pressure helps the self-feed screw pull the bit through dense timber without binding. Forcing the bit or drilling at an angle can dull the cutting edges prematurely and increase motor strain.

Questions about this item

What does the 18-inch overall length mean for reach in deep timber?

The 18-inch overall length lets you drill through thick beams or poles in a single pass without needing an extension, so you can complete deep holes faster and with less repositioning.

How does the 3/4-inch diameter perform when boring clean holes in hardwood?

The 3/4-inch double-flute, double-cut design removes chips efficiently and stays balanced, producing smooth, circular holes in hardwood while reducing strain on the drill motor and operator fatigue.

Will the 7/16-inch quick-change shank fit my cordless drill?

The 7/16-inch quick-change shank is compatible with standard quick-change chucks and 1/2-inch keyed chucks, so it fits most professional cordless and corded drills used in timber framing and pole-barn work.
