Nail Chipper Duo Auger 18" x 3/4

The WoodOwl 05509 is a pneumatic accessory designed for electricians and plumbers who drill through studs containing hidden nails or screws. Its double-cut design chips fasteners cleanly, leaving a smooth bore for conduit or wiring. The 7/16 quick-change shank fits standard drill chucks for fast swaps on site. The bit is sold new and ships direct from the manufacturer.

Lightweight build and reduced kick-back

The auger’s lightweight construction lessens load on cordless drills, extending battery runtime during repetitive drilling. By nearly eliminating the sudden kick-back common with traditional ship augers, it improves operator control and reduces wrist strain. The cutting geometry stays effective in dense framing lumber. California Proposition 65 warnings apply to this product.

Replaces standard ship augers in nail-heavy work

The Duo upgrades from single-flute ship augers when the job regularly hits embedded fasteners, because the twin cutters fracture nails instead of binding. The jump is worth it for remodel crews pulling wire through older walls where nail density is unpredictable. It is not suited for clean-wood boring where a conventional auger cuts faster, nor for holes larger than the 3/4" diameter this bit provides.

Questions about this item

How do I fit the 7/16 quick-change shank into my drill, and what step do people miss?

Insert the 7/16 quick-change shank fully into the chuck until it locks; the step often missed is pulling the collar back completely before insertion so the shank seats past the detent.

What maintenance will the Nail Chipper Duo Auger need after extended use?

The cutting edges can be resharpened when they dull from nail contact; no other scheduled maintenance is required for the 18" OAL bit.

What limit appears first when drilling continuously through nailed studs with this 3/4" DIA auger?

Heat buildup in the cutting lips reduces chip clearance first; pause to let the steel cool and clear shavings before the edge loses temper.
