L H Dottie Co SPD112 Spade Drill Bit 1.5x6 Inch

Product Description

The L H Dottie Co SPD112 is a spade drill bit sized at 1-1/2 inches wide by 6 inches long, designed for boring large-diameter holes through wood framing, engineered lumber, and similar substrates. Spade bits in this size range are standard tools for electricians, plumbers, and HVAC techs who need to run conduit, pipe, or duct penetrations through studs and joists. The flat paddle-style cutting head removes material quickly with a standard corded or cordless drill driver. The 6-inch length provides added reach for deeper penetrations without requiring an extension.

This bit is well suited for residential and light commercial rough-in work where large-diameter holes are required through wood members. Electricians use spade bits in this range to pull wire or conduit through framing. Plumbers and HVAC installers rely on them for pipe and flex-duct penetrations. The 1-1/2-inch diameter is a common size for 1-1/4-inch pipe clearance and similar trade applications. Sold individually as a single unit.

Installation Notes

Licensed electricians, plumbers, and HVAC technicians typically use spade bits during rough-in framing stages before drywall installation. Ensure the drill is powered off and the bit is fully seated in the chuck before operation. Use appropriate eye protection and secure the workpiece before drilling. Follow applicable NEC, IPC, or IFGC clearance requirements when placing penetrations through structural members.
