Diablo Auger Drill Bit DAG1010 1/4 Inch Wood Boring Tool (7-1/2 Inch Length 3/16 Hex Shank Dura-Tip Dual Edge Nail-Embedded Clean Hole Boring)

Diablo DAG1010 1/4" x 7-1/2" Dura-Tip Self-Feed Nail-Embedded Wood Auger Drill Bit

The Diablo DAG1010 1/4-inch wood auger drill bit drills precise pilot holes for heavy timber screws, bores small-diameter wiring paths through structural framing, penetrates dense hardwoods, and drills through nail-embedded timber without binding. Measuring 7-1/2 inches in total length with a 5-1/2-inch usable drilling depth and an impact-rated 3/16-inch quick-change power hex shank, this high-speed steel boring accessory features a threaded Dura-Tip self-feed screw point and dual cutting spurs to slice directly through hidden fasteners. Outfitted with a two-step cutting action that reduces rotational friction to maximize cordless tool battery runtime, deep high-volume flutes for instant chip evacuation, and precision Swiss engineering, it provides residential remodelers, framers, and cabinetry installers with clean, burr-free boring across structural timber assemblies.

Best Used For:

• Structural Fastener Pilot Hole Drilling: Boring 1/4-inch pilot channels in timber framing, structural ledger boards, and deck posts for 5/16-inch and 3/8-inch lag screws.
• Cabinetry and Trim Carpentry Framing: Drilling clean, tearout-free pass-through holes in dense hardwood face frames, structural studs, and plywood subflooring.
• Nail-Embedded Remodeling and Demolition Framing: Penetrating old-growth studs, wall plates, and reclaimed lumber containing hidden framing nails without bit tip damage.

Key Performance & Safety Features

• Self-Feeding Dura-Tip™ Point: Threaded lead screw draws the bit effortlessly through dry and green wood fibers, eliminating feed strain while penetrating embedded nails.
• Dual Precision Cutting Edges: Twin outer scoring spurs slice clean hole perimeters before chip removal to prevent splintering and exit blowout.
• Two-Step Cutting Geometry: 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 buildup.
• 3/16-Inch Quick-Change Hex Shank: Impact-rated power shank prevents chuck slippage and fits securely into quick-change chucks, impact drivers, and drill drivers.
• High-Speed Steel Metallurgy: Premium heat-treated steel core withstands heavy torsional impact forces from compact cordless power tools.

Technical Specifications

Pro-Tip: When drilling small-diameter pilot holes in dense hardwood posts, let the Dura-Tip self-feeding screw point pull the bit naturally at moderate RPM; avoiding excessive downward pressure ensures smooth chip ejection along the 5-1/2-inch flutes without bit binding.
