Freud DAG1020 Auger Bit 5/16 X 7-1/2 Inch 2 Pack

Product Description

The FREUD DAG1020 is a 5/16-inch by 7-1/2-inch auger bit engineered for drilling through nail-embedded wood in demanding jobsite conditions. The self-feeding dura-tip pulls the bit forward on contact, reducing feed pressure and keeping the operator in control. Dual cutting edges work together to produce a clean, consistent bore through lumber that contains fasteners. Deep spiral flutes clear chips aggressively, maintaining cutting speed across multiple holes on a single battery charge. This bit is sold as a 2-pack and is compatible with both cordless and corded impact drivers and drill drivers. Electricians, plumbers, HVAC installers, and general contractors rely on this bit when running rough-in through framed walls and joists.

The DAG1020 is suited for residential and light commercial rough-in work where drilling through dimensional lumber, engineered wood, and reclaimed material with embedded nails is routine. Typical applications include running conduit, pipe, or duct penetrations through wall studs and floor joists during new construction or retrofit work. The 7-1/2-inch length provides adequate reach for standard framing members without requiring an extension. The 5/16-inch diameter is a common size for low-voltage wiring, small-bore plumbing, and light conduit pass-throughs.

Installation Notes

This bit is installed and operated by licensed electricians, plumbers, HVAC technicians, and carpenters during rough-in phases. Confirm the driver chuck accepts the bit shank before use, and verify that the workpiece is secure before applying power. When drilling through structural members, follow applicable building codes regarding notching and boring limits for joists and studs. Wear appropriate eye protection when drilling through nail-embedded material, as metal fragments may be ejected.
