WoodOwl 05515 Nail Chipper Duo Auger

The WoodOwl 05515 Nail Chipper Duo Auger is a pneumatic accessory built for drilling through studs and framework that contain embedded nails. Its double-cut design chips away fasteners while producing a cleaner hole for conduit and wiring. The 18 inch overall length and 1-1/8 inch diameter suit deep boring tasks. A 7/16 quick-change shank allows fast bit swaps on compatible drills.

Practical limits of the double-cut auger design

The double-cut geometry reduces kick-back when the bit contacts nails, making it safer than traditional ship augers in fastener-heavy lumber. However, the cutting edges will dull faster when repeatedly hitting hardened steel, so frequent resharpening is necessary to maintain progress. The 18 inch length limits use to cavities and stud bays deep enough to accommodate the full bit.

Installation ease and common issues

The 7/16 quick-change shank fits standard quick-change chucks, so installation is a simple push-and-lock action. The lightweight construction reduces strain on the drill motor and battery during extended use. The most common issue is accelerated wear on the cutting lips when the bit encounters dense clusters of nails, requiring regular resharpening to keep the hole clean and the feed rate acceptable.

Questions about this item

Which WoodOwl 05515 size should I pick for drilling through nailed studs?

The 18 inch length and 1-1/8 inch diameter suit deep holes in framing where nails are present, and the 7/16 quick-change shank fits standard impact drivers.

How does the double-cut nail-chipper design behave when it hits a fastener?

The twin cutting edges chip through nails instead of grabbing them, which nearly eliminates the sudden kick-back common with traditional ship augers.

What does the 7/16 quick-change shank limit in practice?

It locks into 7/16 inch hex quick-change chucks, so the bit works with compatible impact drivers and drill adapters but not with round-shank or SDS chucks.
