Crescent Solid Auger Drill Bit CDAG-1349 1 1/4 Inch Boring Tool (Quarter Quick Release Hex Shank 13 Overall Length High Speed Steel Timber Framing)

Crescent CDAG-1349 1-1/4" x 13" Solid Auger Drill Bit with 1/4" Quick-Release Hex Shank

The Crescent CDAG-1349 1-1/4-inch by 13-inch solid auger drill bit bores tearout-free passages through structural framing lumber, heavy floor joists, and double top plates for installing commercial plumbing lines, rigid electrical conduit, and large multi-conductor wire bundles. Engineered from triple-sharpened high-speed steel with an optimized precision cutting spur, this heavy-duty wood-boring accessory yields 40 percent more cut cycles per battery charge and penetrates dense timbers up to 10X faster than conventional spade bits. Outfitted with an expansive 12-inch usable drilling depth, deep dual-flute evacuation channels that rapidly clear thick wood chips to eliminate internal binding and thermal friction, and an impact-rated 1/4-inch quick-release hex shank, it equips commercial electricians, mechanical plumbers, and framing carpenters with smooth, continuous boring across cordless impact drivers and standard rotary drills.

Best Used For:

• Commercial Plumbing and Drain Line Rough-Ins: Boring clean 1-1/4-inch clearance holes through wall studs, sole plates, and joists to route 1-inch nominal CTS piping, rigid PEX conduits, and primary sink drain lines without binding.
• Heavy Electrical Conduit and Feeder Routing: Drilling continuous stud-to-stud pathways to run 1-inch trade size thinwall EMT conduit, armored feeder cables, or large bundles of branch wiring.
• Deep Structural Timber and Beam Penetrations: Boring through dense dimensional lumber, engineered glulam headers, and doubled rim 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.

Technical Specifications

Pro-Tip: The 1-1/4-inch diameter removes significant wood volume; when using a cordless impact driver, operate at maximum trigger speed and let the threaded screw lead feed itself through the stud without leaning your body into the drill to maintain a perfectly perpendicular hole and extend battery runtime.
