Milwaukee 48-13-7137 Bell Hanger Bit 3/8 X 12 Inch

Product Description

The Milwaukee Electric Tool Corp 48-13-7137 is a self-feeding bell hanger drill bit designed for boring holes through wood, plastic, and metal. It measures 3/8 inch in diameter and 12 inches in length, making it well suited for routing wire and cable through framing, joists, and wall cavities. Electricians, low-voltage installers, and HVAC technicians use this bit when fishing conduit, speaker wire, or thermostat cable through tight spaces where a standard bit would fall short. The self-feeding tip pulls the bit forward with each rotation, reducing operator pressure and improving control in overhead or awkward-angle drilling situations.

This bit is commonly used in residential and light commercial construction and retrofit work. It is a go-to tool for electricians pulling branch circuits, bell and doorbell wiring installers, security system technicians, and HVAC techs routing low-voltage control wiring. Its slim 3/8-inch diameter leaves a clean, code-acceptable hole for most wire and cable passes through wood framing and engineered lumber. The 12-inch length provides the reach needed to clear typical 2x4 and 2x6 wall framing in a single pass.

Key Features

• Self-feeding tip reduces drilling pressure and improves control at difficult angles
• 3/8-inch diameter suits low-voltage wire, cable, and small conduit pass-throughs
• 12-inch length reaches through standard wood framing in one pass
• Compatible with wood, plastic, and metal substrates
• Sold in a package of 6 units, suitable for stocking a service van or job site kit

Compatibility

Designed as a standard 3/8-inch shank bell hanger bit compatible with corded and cordless drills and drill-drivers accepting a 3/8-inch round shank.

Installation Notes

This bit is installed and used by licensed electricians, low-voltage technicians, and HVAC installers during rough-in and retrofit wiring work. Always disconnect or de-energize circuits in the work area before drilling near existing wiring. Use appropriate eye protection and confirm there are no hidden utilities, plumbing, or structural members in the drill path before proceeding. Follow NEC and local code requirements for wire protection and hole sizing when routing conductors through framing.
