Milwaukee 48-13-7231 Bell Hanger Bit 5/16x18 in 6 Pack

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-13-7231 is a bell hanger drill bit designed for boring through wood framing, joists, and wall cavities during low-voltage wiring, HVAC control wiring, and plumbing rough-in work. The bit measures 5/16 inch in diameter and 18 inches in length, giving tradespeople the reach needed to feed wire or small-diameter tubing through structural members without disassembling framing. Sold in a package of 6, this bit is built for repetitive drilling tasks on the job site where bit wear is a real-world concern.

Bell hanger bits are a standard tool for electricians, low-voltage technicians, HVAC installers, and plumbers who need to route cables, control wiring, or small lines through wood framing. The 18-inch length is well suited for deep drilling through double top plates, multiple joists, or staggered stud walls in residential and light commercial construction. The 5/16-inch diameter is commonly used for thermostat wire, speaker cable, data cable, and similar applications where a clean, tight passage is required.

Key Features

• 5/16-inch diameter for thermostat wire, low-voltage cable, and similar routing tasks
• 18-inch length provides reach through deep framing assemblies and stacked structural members
• Package of 6 bits supports extended job site use and reduces downtime from bit wear
• Designed for use in standard drill chucks compatible with 5/16-inch shank bell hanger bits

Compatibility

Designed as a standard bell hanger drill bit for use in residential and light commercial rough-in applications where a 5/16-inch diameter, 18-inch length bit is required.

Installation Notes

Bell hanger bits are typically used by electricians, HVAC technicians, and low-voltage installers during rough-in framing stages. Always confirm that drilling locations avoid structural load-bearing members where codes restrict notching or boring, as referenced in the IRC and IBC boring and notching provisions. Use appropriate eye protection and ensure the drill is properly secured before beginning. Follow local building codes regarding minimum edge distances when boring through joists and studs.
