Dewalt DW1594 Spade Bit 7/8 X 16 Inch Wood Boring

Product Description

The DEWALT DW1594 is a 7/8-inch by 16-inch spade bit designed for boring through wood framing, studs, joists, and other lumber. The extended 16-inch length allows electricians, plumbers, and HVAC installers to drill through deep framing members and wall assemblies in a single pass without extensions. The 7/8-inch diameter is a common size for routing conduit, pipe, and flex duct penetrations through structural lumber. At 0.28 pounds, the bit is lightweight enough for overhead and confined-space work. It is sold individually and fits standard 3/8-inch and 1/2-inch drill chucks.

This bit is suited for rough-in trade work where long-reach wood boring is required. Electricians running branch circuits through wall framing, plumbers routing supply or drain lines, and HVAC technicians pulling refrigerant lines or low-voltage control wiring through studs and plates will find the extended reach of this bit practical for production drilling. It is appropriate for both residential new construction and light commercial framing applications.

Key Features

• 7/8-inch diameter for standard conduit, pipe, and flex penetration sizing
• 16-inch overall length for single-pass drilling through deep framing assemblies
• Lightweight at 0.28 pounds for reduced fatigue during overhead or repetitive drilling

• Sold individually — one bit per unit

Compatibility

Designed as an OEM-style replacement or direct-use spade bit for standard drill drivers and right-angle drills accepting a hex or round shank spade bit in 3/8-inch or 1/2-inch chuck sizes.

Installation Notes

Spade bits of this length are typically used by licensed electricians, plumbers, and HVAC technicians during rough-in phases. Always confirm the drilling path is clear of hidden utilities before boring. Secure the workpiece and use a drill with adequate torque to prevent bit binding in dense lumber. Consult applicable codes such as the NEC or IPC for minimum edge-distance and hole-size requirements when drilling through structural members.
