The MILWAUKEE ELECTRIC TOOL CORP 48-13-1120 is a self-feeding auger bit designed for boring clean, accurate holes in wood framing, rough lumber, and similar materials. Measuring 1-1/8 inches in diameter and 6-1/2 inches in length, this bit is built for repetitive production drilling in residential and light commercial construction. The self-feeding tip pulls the bit through material with reduced operator effort, maintaining consistent hole geometry without wandering. At 6.15 pounds per package of six units, each individual bit is lightweight enough for extended overhead or awkward-angle drilling. Electricians, plumbers, and general carpenters regularly reach for this style of bit when running conduit or pipe through structural members.
This auger bit is well suited to through-drilling wood studs, joists, and plates for wire, pipe, and conduit runs. The 1-1/8-inch diameter accommodates common rough-in clearance requirements encountered in residential wiring and plumbing rough-in work. The 6-1/2-inch overall length provides enough reach to clear double plates and thick framing members without requiring an extension. Packaged in a quantity of six, it supports crew-level tool distribution or replacement stocking on active job sites.
Designed as an OEM-style auger bit compatible with standard hex or round-shank drill chucks found on corded and cordless right-angle drills and standard drill drivers used in framing and rough-in applications.
This bit is typically used by electricians, plumbers, and carpenters during rough-in framing stages. Secure the bit fully in the drill chuck before operation and verify the chuck is tightened. Keep drilling speed consistent to avoid binding, and back the bit out periodically to clear chips from deep holes. Follow applicable NEC or IPC clearance requirements when boring through structural members for wire or pipe routing.
