Greenlee 34A Self-Feeding Spade Bit, Hexagonal Shank

The Greenlee 34A Self-Feeding Spade Bit is a forged and heat-treated boring bit built for electricians, carpenters, and tradespeople who need to cut clean holes through hardwood, softwood, plywood, and drywall. Featuring a 1/4 IN (6.4 mm) quick-change hexagonal shank, this bit is designed for use in 1/4 IN (6.4 mm) or larger power drills. Its innovative self-feeding design pulls the bit into the work material, requiring less operator effort and reducing vibration during use, which helps improve control and reduce fatigue on long jobs.
