L H Dottie Co SDF118 Speed-d-feed Spade Bit 1-1/8 Inch

Product Description

The L H Dottie Co SDF118 is a 1-1/8 inch Speed-D-Feed spade bit designed for fast, aggressive boring through wood framing, sheathing, and dimensional lumber. The self-feeding screw tip pulls the bit through material without requiring constant downward pressure, reducing fatigue on long drilling runs. Electricians, plumbers, and HVAC installers use this style of bit when running wire, conduit, pipe, or ductwork through wood stud walls and floor joists. The 1-1/8 inch cutting diameter makes it well suited for standard trade rough-in work where moderate hole sizes are required.

This bit is used in residential and light commercial construction and retrofit applications. It is a common choice during rough-in stages when trade contractors need to bore multiple holes through framing members in a single work session. The self-feeding design is compatible with standard corded and cordless drill/drivers and right-angle drills, which are the typical tools used in framing and mechanical rough-in environments.
