Crescent CDAG-1343 15/16" x 13" Solid Auger Drill Bit with 1/4" Quick-Release Hex Shank The Crescent CDAG-1343 15/16-inch by 13-inch solid auger drill bit bores tearout-free utility penetrations, large electrical service feeds, and commercial plumbing lines 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 and Heavy-Gauge Electrical Rough-Ins: Boring clean 15/16-inch diameter pass-through holes in timber studs and double top plates to pull large service entrance cables, armored MC cable, or bundled branch circuits without insulation chafing. Plumbing and Heavy Water Line Installation: Sinking clearance pathways through sole plates, rim joists, and subfloors for 3/4-inch nominal PEX tubing, copper pipe, and drain lines. 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.
