Dewalt Accessories DW1584 Spade Bit 1-1/4 X 6 Inches

Product Description

The DEWALT ACCESSORIES DW1584 is a 1-1/4 inch by 6 inch spade bit engineered for high-demand wood boring applications. The full-length heat-treated shank resists bending and breaking under heavy use, while cutting spurs at the tip produce a clean, accurate hole finish. The Extreme Speed Channel clears chips rapidly, reducing heat buildup and improving drilling speed through thick stock. The 1/4 inch ball groove hex shank fits all quick-change chuck systems and locks securely to prevent slippage. Rated for use with impact drivers, this bit handles repeated high-torque cycles without shank failure. The package includes 3 bits.

This spade bit is suited for residential and light commercial work where electricians need to bore passage holes for wiring runs, plumbers need clearance holes for pipe installations, and deck builders need holes for lag bolts and fasteners. It performs in both natural wood and engineered wood materials including LVL, OSB, and dimensional lumber. The 6 inch length provides reach through standard wall and floor framing without requiring an extension.

Compatibility

Designed for use with impact drivers and standard 1/4 inch quick-change drill/driver systems. Suitable for boring passage holes in natural wood, LVL, OSB, and other engineered wood materials in electrical, plumbing, and general carpentry applications.

Installation Notes

Licensed electricians and plumbers typically install this bit when boring framing for wire or pipe runs in accordance with NEC and IPC clearance requirements. Confirm the quick-change chuck is fully seated and the ball groove is engaged before drilling. Keep steady forward pressure to allow the cutting spurs to score the wood cleanly and reduce tearout on the exit face. Do not force the bit if chip buildup stalls rotation — retract periodically to clear the channel.
