Diablo Auger Drill Bit DAG1070 5/8 Inch Wood Boring Tool (7-1/2 Inch Length 7/16 Hex Shank Dura-Tip Dual Edge Nail-Embedded Clean Hole Boring)

Diablo DAG1070 5/8" x 7-1/2" Dura-Tip Self-Feed Nail-Embedded Wood Auger Drill Bit

The Diablo DAG1070 5/8-inch wood auger drill bit bores clean cable passages through timber studs, drills through-holes for 1/2-inch threaded anchor bolts, penetrates dense structural joists, and drills nail-embedded framing lumber without jamming. Measuring 7-1/2 inches in overall length with a 5-1/2-inch drilling depth and an impact-rated 7/16-inch quick-change hex shank, this high-speed steel boring tool features a threaded Dura-Tip self-feeding screw point and dual cutting spurs to cut smoothly through embedded framing fasteners. Designed with a two-step cutting action that minimizes breakthrough blowout, deep spiral flutes for rapid chip ejection and longer cordless tool runtime, and precision Swiss engineering, it provides residential electricians, framers, and deck builders with clean, fast hole-boring performance across heavy timber assemblies.

Best Used For:

• Electrical Rough-In and Cable Routing: Boring 5/8-inch clean holes through double top plates, studs, and floor joists for 12/2 and 14/2 Romex branch wiring.
• Deck Framing and Structural Carriage Bolt Holes: Drilling clean pass-through channels in multi-ply 2x10 joists and 4x4 support posts for 1/2-inch structural bolts.
• Nail-Embedded Remodeling and Demolition Framing: Boring through reclaimed lumber, floor plates, and structural posts containing hidden framing nails without tip chipping.

Key Performance & Safety Features

• Self-Feeding Dura-Tip™ Point: Threaded lead screw draws the bit effortlessly through dry and pressure-treated lumber, eliminating feed strain while penetrating embedded nails.
• Dual Precision Cutting Edges: Twin outer scoring spurs slice clean hole perimeters before chip removal to prevent wood splintering and exit blowout.
• Two-Step Cutting Action: Progressive cutting profile reduces rotational torque resistance, significantly lowering battery drain on cordless drill drivers and impact wrenches.
• Deep Chip Evacuation Flutes: Wide polished flutes quickly eject wood shavings out of deep holes to eliminate clogging and reduce friction heat.
• 7/16-Inch Quick-Change Hex Shank: Heavy-duty power hex shank provides non-slip chuck grip and locks securely into 7/16" quick-change adapters, drill chucks, and high-torque impact tools.
• High-Speed Steel Construction: Premium heat-treated steel core withstands heavy torsional impact forces from compact cordless power tools.

Technical Specifications

Pro-Tip: When boring through stacked wall plates or deep framing headers, keep the drill motor aligned straight and let the threaded Dura-Tip pull the bit steadily at medium RPM; avoiding manual rocking maintains true concentricity and allows the deep flutes to clear chips efficiently without packing.
