Milwaukee 48-13-7237 Bell Hanger Bit 3/8x18 Inch 6 Pack

Product Description

The Milwaukee Electric Tool Corp 48-13-7237 is a bell hanger drill bit designed for boring through wood framing, plates, and structural members during low-voltage wiring and cable routing installations. Measuring 3/8 inch in diameter and 18 inches in length, this bit reaches deep into wall cavities and framing bays where standard-length bits fall short. It is sold as a pack of 6, making it practical for contractors and service techs who go through bits regularly on larger jobs. Electricians, alarm installers, and A/V and data cabling crews rely on bell hanger bits for clean, accurate passes through tight structural spaces.

This bit is used in residential and light commercial construction and retrofit work where low-voltage wiring, speaker wire, thermostat cable, coaxial cable, or structured wiring must be routed through wood framing. The 18-inch length makes it well-suited for drilling through double top plates, deep headers, or stacked framing without requiring an extension. The 3/8-inch diameter accommodates common wiring bundles and conduit drop applications. It fits standard 3/8-inch and 1/2-inch chuck drill drivers.

Key Features

• 3/8-inch diameter x 18-inch length for deep-reach drilling through wood framing

• Packed 6 units per package, reducing reorder frequency on multi-unit jobs

Compatibility

Designed as an OEM-style bell hanger bit for use with standard 3/8-inch or 1/2-inch chuck corded and cordless drill drivers used in low-voltage and electrical rough-in work.

Installation Notes

Bell hanger bits are typically installed and used by electricians, low-voltage technicians, and structured wiring contractors. Always confirm framing layout and check for existing wiring, plumbing, or obstructions before drilling. Use appropriate eye protection and follow applicable NEC and local code requirements when routing wiring through framing cavities. Bits should be inspected for wear or damage before each use and replaced if the cutting tip is chipped or the shank is bent.
