1-1/8" x 8" Nail Busting Auger Bit

1-1/8" X 8" NAIL BUSTING AUGER BIT

Built for boring through wood where hidden nails can stop ordinary wood bits, the Benchmark Abrasives 1-1/8" x 8" nail busting auger bit combines fully heat-treated steel construction with a self-feed screw point and resharpenable cutting head. The screw point helps pull the bit into the work while the auger flute carries chips away from the cutting area for efficient hole boring.

The black oxide finished flute provides a durable working surface, while the 7/16" hex shank provides a secure grip for compatible drill chucks. Designed for wood and nail-embedded wood, this auger bit is well suited for construction, remodeling, electrical, plumbing, and other trades where larger holes must be bored through framing and timber that may contain nails.

Product Specifications

Features

• Nail-busting design – Made for boring through wood and nail-embedded wood encountered in framing and renovation work.
• Self-feed screw point – Helps pull the auger into the wood for controlled, efficient boring.
• Fully heat-treated construction – Built for demanding wood-boring applications.
• Black oxide flute – Provides a durable finish on the auger flute.
• Chip-clearing flute design – Carries wood chips away from the cutting area as the bit advances.
• Resharpenable head – Allows the cutting head to be sharpened as needed to help maintain cutting performance.
• 7/16" hex shank – Designed for compatible drill chucks capable of securely accepting the larger hex shank.

Applications & Performance

The 1-1/8" Nail Busting Auger Bit is designed for drilling controlled holes through wood and nail-embedded wood. Typical applications include:

• Boring through wall studs, joists, framing, and timber
• Creating pathways for electrical wiring
• Plumbing and mechanical installation work
• Construction and remodeling
• General wood boring where embedded nails may be encountered
• Drilling access holes for hardware and other installations

The self-feed screw point draws the bit into the wood while the auger flute clears chips from the hole. Use this bit for wood and nail-embedded wood; choose dedicated bits for metal and masonry.

Materials

Recommended Materials:

• Softwood
• Hardwood
• Dimensional lumber
• Framing lumber
• Timber
• Nail-embedded wood

Select the cutting diameter based on the finished hole required for the application. The 1-1/8" cutting diameter determines hole size, while the 7/16" hex shank determines which drill chucks can hold the bit.

Machine Compatibility

Designed for drills with a chuck capable of securely accepting the 7/16" hex shank and with adequate auger capacity for a 1-1/8" bit.

Compatible examples include:

• Makita® XAD05Z 18V LXT Right-Angle Drill
• Makita® XAD03Z 36V (18V X2) LXT Right-Angle Drill
• Milwaukee® 2809-20 M18 FUEL SUPER HAWG

Compatibility examples are based on published chuck specifications and auger capacities. Always verify the exact tool model, chuck engagement, and manufacturer operating limits before use. When using a hammer drill, operate in rotary drilling mode with hammer action turned off.

Important: The 7/16" hex shank does not directly fit standard 1/4" hex impact-driver chucks.

Safety Tips

• Always wear appropriate eye protection, hearing protection, and other PPE required for the application.
• Secure the workpiece before drilling whenever practical.
• Disconnect power before changing bits, and tighten the chuck securely before drilling.
• Use auxiliary handles when required by the drill manufacturer, especially with high-torque right-angle drills.
• Start at low speed with the screw point against the wood.
• Keep hands and loose clothing away from the rotating bit.
• Use rotary drilling mode with hammer action off when using compatible hammer drills.
• Follow the drill manufacturer's recommended auger capacities, operating speeds, and safety instructions.
• Do not use a tool whose published auger capacity is smaller than the bit diameter.
• Inspect the cutting edges and shank before each use. Do not use a damaged or improperly secured bit.
