Greenlee 50122606 Self-Feeding Spade Bit, 3/4" Diameter, Hex Shank

Greenlee 50122606 Self-Feeding Spade Bit, 3/4" Diameter, 6-1/4" Length

The Greenlee 50122606 is a self-feeding spade bit built for electricians and tradespeople who need to bore clean, accurate holes through hardwood, softwood, plywood, and drywall. This bit measures 6-1/4" (158.800 MM) in overall length with a 3/4" (19.100 MM) bit diameter, giving installers the reach and cutting capacity needed for common electrical rough-in work such as running cable and conduit through framing members. The bit features a 1/4" (6.400 MM) hexagonal shank, which provides a secure, slip-resistant fit in drill chucks and impact-rated drivers, helping maintain consistent boring speed and reducing bit walk during use. Compact overall product dimensions of 8.800 IN length, 3.000 IN width, and 0.100 IN height keep the bit manageable for job-site storage and transport between rough-in tasks.

Key Features
