Nail Chipper Duo Auger 18" x 1-1/4

This pneumatic accessory is designed for electricians and carpenters who drill through nail-embedded framing. The double-cut design chips away at fasteners to leave a cleaner hole for conduit and wiring runs. It nearly eliminates the kick-back common with traditional ship augers when striking hidden nails. The 7/16 quick-change shank fits standard impact drivers and drill chucks.

Lightweight design extends tool and battery life

Reduced mass lowers the load on cordless drills, helping batteries last longer during repetitive boring tasks. The cutting geometry requires less feed pressure, which keeps motor temperatures lower during extended use. Vibration transmitted to the operator is diminished because the bit shaves nails rather than snagging them. Resharpening is straightforward, maintaining consistent cutting efficiency over time.

7/16 quick-change shank speeds bit swaps

The hex shank locks into quick-change adapters without tools, reducing downtime between hole locations. An 18-inch overall length reaches through deep studs and joists in a single pass. The 1-1/4 inch diameter clears space for larger conduit bundles or multiple cables. California Proposition 65 warnings apply for chemicals known to cause cancer and reproductive harm.

Questions about this item

How do I fit the 7/16 quick-change shank into my drill and what is the common mistake?

Insert the shank fully until the collar locks; the step users miss is not pushing past the first detent, leaving the bit loose under load.

When will the 1-1/4 inch Duo Auger need resharpening or replacement?

Resharpen when nail-chipping performance drops; the cutting edges are designed for easy filing, so replacement is only needed once the flutes wear below usable depth.

What limits continuous drilling with this 18 inch auger in heavy framing?

Battery drain and heat build-up in the drill motor appear first; the lightweight design reduces strain, but sustained high-torque work will hit the tool’s thermal limit before the bit does.
