Crescent Solid Auger Drill Bit CDAG-1333 5/8 Inch Boring Tool (1/4 Quick Release Hex Shank 13 Overall Length High Speed Steel Timber Drilling)

Crescent CDAG-1333 5/8" x 13" Solid Auger Drill Bit with 1/4" Quick-Release Hex Shank

The Crescent CDAG-1333 5/8-inch by 13-inch solid auger drill bit bores tearout-free wiring penetrations, utility conduits, and dowel passages through structural timber framing, floor joists, and treated lumber. Engineered from triple-sharpened high-speed steel with a precision-machined cutting edge, this high-velocity boring accessory delivers up to 10X faster penetration and yields 40 percent more drilled holes per battery charge cycle compared to standard spade bits. Outfitted with an expansive 12-inch usable drilling depth, deep dual-flute extraction channels that rapidly exhaust wood chips to reduce cutting friction, and an impact-rated 1/4-inch quick-release hex shank, it equips commercial electricians, residential plumbers, and framing carpenters with smooth, stall-free drilling across standard drills and high-torque impact drivers.

Best Used For:

• Electrical Cable Rough-Ins: Boring clean, consistent 5/8-inch holes through stacked 2x4 and 2x6 wall studs to pull non-metallic sheathed Romex cable without snagging.
• Deep Timber and Joist Penetrations: Drilling through thick structural beams, double floor joists, and deck framing members up to a full 12-inch drilling depth.
• Plumbing and PEX Water Line Routing: Sinking fast clearance pathways through sill plates, rim joists, and subflooring for flexible potable water lines and small tubing runs.

Key Performance & Safety Features

• Triple-Sharpened High-Speed Steel: Advanced cutting tooth profile stays sharp across dense hardwoods and delivers up to 10X faster cutting velocity than standard drill bits.
• 40% More Holes Per Charge: Low-friction cutting geometry and efficient chip flow reduce tool motor drag, significantly extending cordless drill battery runtime.
• Deep Dual-Flute Evacuation: High-capacity spiral flutes actively clear large wood shavings and chips away from the cutting tip to eliminate internal borehole packing and heat buildup.
• Extended 12-Inch Boring Depth: Long 13-inch overall shaft reaches through double top plates and deep wall cavities without requiring separate bit extensions.
• 1/4" Quick-Release Hex Shank: Precision-grooved hex shank prevents slippage inside three-jaw drill chucks and seats directly into standard quick-change impact drivers.
• Clean Hole Cutting Edges: Optimized peripheral cutting spurs score wood fibers before the main lift blade engages, preventing exit blowout and surface splintering.

Technical Specifications

Pro-Tip: When boring through stacked wall studs or deep rim joists with an impact driver, let the sharp cutting spur pull the bit through the wood at high RPM; avoid rocking the tool back and forth to maintain a concentric, bind-free channel.
