Crescent Solid Auger Drill Bit CDAG-1346 1 1/16 Inch Boring Tool (1/4 Quick Release Hex Shank 13 Overall Length High Speed Steel Wood Drilling)

Crescent CDAG-1346 1-1/16" x 13" Solid Auger Drill Bit with 1/4" Quick-Release Hex Shank

The Crescent CDAG-1346 1-1/16-inch by 13-inch solid auger drill bit bores tearout-free conduit pathways, heavy-gauge electrical service lines, and commercial plumbing runs through structural timber framing, stacked wall plates, and heavy floor joists. 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 lumber 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 Electrical Service Rough-Ins: Boring clean 1-1/16-inch diameter pass-through holes in timber studs and double top plates to pull heavy-gauge service entrance conductors, 3/4-inch flexible conduit, or multiple armored MC cables without insulation drag.
• Plumbing and Hydronic Pipe Rough-Ins: Sinking clearance pathways through sole plates, rim joists, and subfloors for 3/4-inch nominal CTS copper tubing, PEX water supply lines, and small drain pipes.
• Deep Structural Timber and Beam Penetrations: Boring through dense dimensional framing lumber, engineered glulam headers, and doubled floor joists up to a full 12-inch working depth.

Key Performance & Safety Features

• Triple-Sharpened High-Speed Steel: Heavy-duty cutting edges stay sharp longer when cutting through dense construction timber, boring 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.

Pro-Tip: The 1-1/16-inch diameter provides the ideal clearance margin for running 3/4-inch nominal water lines or electrical conduits through framing without snug binding; maintain high trigger RPM and let the self-feeding threaded spur pull the cutter through the timber naturally.
