Crescent Solid Auger Drill Bit CDAG-1335 11/16 Inch Boring Tool (1/4 Quick Release Hex Shank 13 Overall Length High Speed Steel Wood Drilling)

Crescent CDAG-1335 11/16" x 13" Solid Auger Drill Bit with 1/4" Quick-Release Hex Shank

The Crescent CDAG-1335 11/16-inch by 13-inch solid auger drill bit bores clean, blowout-free passages through structural framing lumber, stacked wall studs, and heavy timber joists for running non-metallic electrical cable and water lines. Engineered from triple-sharpened high-speed steel with an optimized precision cutting spur, this wood-boring accessory yields 40 percent more cut cycles per battery charge and penetrates substrates up to 10X faster than conventional spade bits. Outfitted with an expansive 12-inch usable drilling depth, deep dual-flute evacuation channels that eliminate internal chip binding and thermal friction, and an impact-rated 1/4-inch quick-release hex shank, it equips commercial electricians, residential plumbers, and framing carpenters with smooth, continuous boring across cordless impact drivers and standard rotary drills.

Best Used For:

• Commercial and Residential Wiring Rough-Ins: Boring clean 11/16-inch diameter pass-through holes in timber studs and top plates to pull multiple electrical Romex runs or heavy armored cables without friction drag.
• Deep Timber Framing and Joist Penetrations: Boring through dense dimensional framing, engineered glulam beams, and doubled floor joists up to a full 12-inch working depth.
• Plumbing and Flexible Tubing Routing: Sinking clean, tearout-free conduit pathways through sole plates, rim joists, and subfloors for PEX water lines and small condensation drain pipes.

Key Performance & Safety Features

• Triple-Sharpened High-Speed Steel: Heavy-duty cutting edges stay sharp longer when cutting through dense construction timber, cutting up to 10X faster than generic flat spade bits.
• 40% More Cuts Per Battery Charge: Reduced-friction flute geometry and low-drag cutting spurs decrease motor draw to extend cordless tool operational life.
• High-Capacity Dual-Flute Evacuation: Deep dual flutes rapidly eject large wood chips away from the cutting spur to prevent bore packing and motor bog-down.
• Extended 12-Inch Boring Depth: Long 13-inch tool length allows tradesmen to bore completely through double top plates and deep wall studs without using an arbor extension.
• 1/4" Quick-Release Hex Shank: Precision-milled quick-change hex base eliminates chuck slippage in drill drivers and locks directly into high-torque cordless impact drivers.
• Precision Spur Clean Cutting Edges: Scored perimeter spurs slice cleanly through wood grains before chip lifting occurs, preventing backside exit breakout.

Technical Specifications

Pro-Tip: When boring deep holes through wet, pressure-treated lumber or stacked rim joists, maintain a high trigger speed while letting the self-feeding screw tip pull the bit forward; this allows the dual flutes to clear wet wood pulp cleanly without clogging the borehole.
