Crescent CDFP-SET6 6-Piece Impact-Rated Flat Spade Drill Bit Set (3/8" to 1")

The Crescent CDFP-SET6 6-piece flat spade drill bit set bores clean, fast utility pass-through holes across timber framing, softwood studs, engineered joists, and plywood panels with a full 6-inch drilling depth. Engineered with advanced chip-clearing cutting grooves and a reinforced spur-and-point geometry, each spade bit expels heavy wood chips rapidly to prevent hole binding and maximize drilling velocity. Outfitted with an impact-rated 1/4-inch quick-release hex shank featuring an engineered torsion flex zone to absorb high torque spikes from cordless impact drivers, this 6-piece wood boring collection covers diameters from 3/8 inch to 1 inch to equip residential electricians, mechanical plumbers, and framing carpenters with aggressive, jam-free hole-making performance.

Best Used For:

  • Electrical Wire and Conduit Routing: Boring 1/2-inch, 5/8-inch, and 3/4-inch utility penetrations through wall studs, headers, and floor joists for multi-conductor Romex and low-voltage cable runs.
  • Plumbing Supply Line Rough-Ins: Drilling aligned 7/8-inch and 1-inch clearance holes through framing timbers for PEX water lines, copper tubing, and CPVC piping.
  • General Framing and Subfloor Boring: Rapidly drilling clean holes through dimensional lumber (2x4, 2x6), OSB sheathing, and plywood subflooring without motor bogging.

Key Performance & Safety Features

  • Reinforced Tip Geometry: Specially engineered center pilot point and cutting spurs resist chipping and premature dulling, extending overall tool life.
  • Advanced Cutting Grooves: Precision-milled paddle face grooves accelerate chip evacuation to reduce friction and eliminate hole packing.
  • Impact-Rated Torsion Zone: Engineered shank flex zone absorbs peak rotary impact shocks to prevent shank breakage in high-torque drivers.
  • 1/4-Inch Quick-Release Hex Interface: Locks firmly into 1/4-inch impact driver quick-change chucks and 3-jaw drill chucks without slipping under heavy loads.
  • High-Speed Material Evacuation: Optimized paddle bevel slices wood fibers cleanly, producing smooth entry holes and clean exits.
  • 6-Piece Comprehensive Range: Provides all high-demand residential trade diameters including 3/8", 1/2", 5/8", 3/4", 7/8", and 1" in one organized set.
