Eagle Cutting Tool SB-WB1.125 Spade Drill Bit

Product Description

The EAGLE CUTTING TOOL SB-WB1.125 is a spade drill bit designed for boring large-diameter holes through wood and wood-composite materials. The bit measures 1.125 inches in diameter with a 6-inch overall length, giving it extended reach for deep boring applications where a standard-length bit cannot access the work area. At 0.14 pounds, it is lightweight enough for extended overhead or confined-space use. Electricians, plumbers, and HVAC technicians rely on this style of bit when running conduit, pipe, or duct penetrations through framing members and dimensional lumber.

This spade bit is suited for residential and light commercial rough-in work where 1.125-inch clearance holes are required. Common applications include drilling through wall studs, floor joists, and top plates to route wiring, small-diameter pipe, or flex duct. The 6-inch length provides enough reach to penetrate double framing members or thick structural lumber without requiring an extension. It is typically driven with a standard corded drill or heavy-duty cordless drill operating at appropriate low-speed, high-torque settings.

Key Features

• 1.125-inch cutting diameter for oversized rough-in hole boring
• 6-inch overall length for extended reach into deep framing cavities
• Lightweight at 0.14 pounds for reduced fatigue during repetitive drilling
• Spade-style geometry suited for fast material removal in wood and wood composites

Compatibility

Designed as an OEM-style replacement or standard trade spade bit compatible with drills accepting a standard hex or straight shank drive configuration appropriate for spade bits of this diameter.

Installation Notes

This bit is installed and used by electricians, plumbers, and HVAC technicians during rough-in phases of construction or remodel. Secure the workpiece before drilling and use a drill with sufficient torque capacity for 1.125-inch diameter boring. Wear appropriate eye and hand protection, as spade bits can grab in dense material. Follow all applicable NEC, IPC, and IFGC clearance requirements when routing trade work through structural members.
