DeWalt DW1688 1-1/16" x 17" Power Ship Auger Wood Boring Bit

The DeWalt DW1688 1-1/16-inch by 17-inch power ship auger bit bores deep, straight holes through heavy structural framing timbers, utility poles, laminated veneer lumber (LVL), and nail-embedded reclaimed wood. Manufactured from heat-treated and tempered alloy tool steel, this industrial wood-boring bit features dual cutting edges that slice through hidden framing nails and structural fasteners without catastrophic tooth fracture. Outfitted with an aggressive self-feeding lead screw spur, a high-clearance hollow center flute for fast chip evacuation, and a standardized 7/16-inch ball groove quick-change shank, it equips commercial electricians, plumbers, utility linemen, and timber framers with rapid penetration rates and jam-free deep-hole drilling performance.

Best Used For:

  • Commercial Electrical and Utility Rough-Ins: Drilling 1-1/16-inch pathway holes through stacked structural wall plates, floor joists, and utility poles to pull heavy electrical feeder cables and conduit.
  • Plumbing and Mechanical Line Penetrations: Boring clean, continuous chases across multiple dense framing studs and timber beams for water supply lines and copper piping.
  • Timber Framing and Heavy Wood Fabrication: Boring deep bolt-through holes in structural glulam beams, railroad ties, landscape timber retaining walls, and recycled nail-embedded lumber.

Key Performance & Safety Features

  • Nail-Ready Dual Cutting Edges: Hardened cutting wings withstand high-energy impacts against embedded framing nails, wire staples, and hidden screws without chipping.
  • Aggressive Self-Feeding Screw Point: Threaded lead spur draws the bit steadily into tough lumber with minimal forward push pressure required from the operator.
  • Hollow Center Deep Flute Design: Wide spiral chamber expels heavy wood chips and damp shavings rapidly upward to eliminate binding and friction heat in deep runs.
  • Tempered Hardened Alloy Steel: High-strength metallurgy resists torsional twisting and shaft bending under extreme high-torque drill and impact workloads.
  • 7/16-Inch Quick-Change Ball Groove Shank: Precision-machined shank locks securely into 7/16-inch quick-release chucks and high-torque right-angle drill adapters without slipping.
  • Extended 17-Inch Reach Architecture: Full 17-inch overall length provides the necessary depth clearance to bore through thick structural wood posts and multi-stud assemblies in a single pass.

Pro-Tip: When boring deep structural holes through dense green or pressure-treated timbers, maintain high motor RPM and feather the feed slightly; clearing wood chips every 4 to 6 inches prevents flute packing and keeps the dual cutting edges running at peak speed.
