L H Dottie Co SPD1 Spade Drill Bit 1x6 Inch

Product Description

The L H Dottie Co SPD1 is a 1-inch by 6-inch spade drill bit designed for boring large-diameter holes through wood framing, blocking, and rough construction materials. The flat paddle-style blade cuts efficiently at standard drill speeds and is compatible with most corded and cordless power drills equipped with a 3/8-inch or 1/2-inch chuck. Electricians, plumbers, and HVAC installers rely on spade bits like the SPD1 to run conduit, pipe, and ductwork penetrations through structural members quickly and cleanly. The 6-inch length provides enough reach for single-stud penetrations without an extension.

The SPD1 is suited for residential and light commercial rough-in work where a clean, fast hole is needed through dimensional lumber, engineered wood panels, and similar materials. It is a common tool-of-trade for electricians routing wire runs, plumbers establishing drain and supply line paths, and HVAC technicians creating duct and refrigerant line penetrations through wall and floor assemblies. Sold individually, it is easy to stock as a single replacement or add-on bit.

Installation Notes

Spade bits are installed by trade professionals including electricians, plumbers, and HVAC technicians during rough-in phases. Ensure the drill is powered off and the bit is fully seated and secured in the chuck before operation. Maintain steady feed pressure and reduce speed when approaching the exit face of the material to minimize tear-out. Always verify that no concealed utilities are present in the work area before drilling into walls, floors, or ceilings.
