Greenlee 50203592 Hex-Shank Spade Bit, 1-1/4" x 6-1/4"

The Greenlee 50203592 Hex-Shank Spade Bit is a 1-1/4" (31.800 MM) diameter wood boring bit with an overall length of 6-1/4" (158.800 MM), purpose-built for electricians and tradespeople who need to bore clean, accurately sized holes for conduit, wiring, and cable runs through framing members and building materials. The bit is fitted with a 1/4" (6.400 MM) hexagonal shank that seats securely and resists slipping in standard drill drivers, keeping the bit centered and reducing wobble as it bores. Greenlee rates this spade bit for boring hardwood, softwood, plywood, and drywall, making it a versatile choice across the mix of materials found on residential and commercial jobsites during rough-in electrical work, panel installations, and general construction wiring tasks. Compact and lightweight, it measures 8.100 IN in length, 1.700 IN in width, and 0.100 IN in height, with a volume of 1.377 CI, so it stows easily in a tool bag or drill kit alongside other boring bits. As a Greenlee product, it is engineered to deliver dependable, repeatable performance on the job site where precise hole sizing and fast, clean material removal directly affect installation quality and labor time.
