The EAGLE CUTTING TOOL SB-WB1.000 is a 1-inch by 6-inch long spade bit designed for boring large-diameter holes through wood framing, studs, and structural members. The extended 6-inch length gives tradespeople the reach needed to drill through thick assemblies without extensions. Electricians, plumbers, and HVAC installers rely on spade bits like this when routing conduit, pipe, or flex duct through wood framing during rough-in work. The 1-inch cutting diameter is a common size for standard trade applications.
This spade bit is suited for residential and light commercial rough-in work where clean, fast holes through dimensional lumber are required. Typical applications include drilling through wall plates, floor joists, and ceiling framing for wire runs, pipe chases, and duct penetrations. The 6-inch overall length provides clearance in tight framing cavities where shorter bits cannot reach the target depth in a single pass.
Designed as a standard hex-shank spade bit compatible with corded and cordless drills accepting a 1/4-inch or larger hex-shank bit holder. Suitable for use in wood and wood-composite framing materials.
This bit is installed and used by electricians, plumbers, and HVAC technicians during rough-in phases. Ensure the drill is set to an appropriate speed for large-diameter spade bits in wood — high torque at moderate RPM reduces splintering and bit deflection. Secure the workpiece before drilling and clear chips regularly to prevent binding. Follow all applicable NEC, IPC, or IFGC clearance requirements for hole placement near structural members.
