Milwaukee 48-13-7131 Bell Hanger Drill Bit 5/16 in

Product Description

The MILWAUKEE 48-13-7131 is a 5/16-inch bell hanger drill bit designed for boring through wall cavities and structural members during low-voltage wiring installations. The bit measures 12 inches in length, providing the extended reach needed to drill through deep framing without repositioning. A wire-pulling hole at the tip allows the installer to attach cable directly to the bit and pull it back through the drilled path in a single motion. This bit ships as a single unit and is built for repeated use in residential and light commercial wire-routing work.

This bit is suited for electricians, alarm and security installers, data and telecom technicians, and HVAC controls technicians routing low-voltage signal cable. Common applications include pulling computer network cable, phone wire, security sensor wire, and similar small-diameter cabling through wood framing, top plates, and wall cavities. The extended 12-inch length makes it especially useful in retrofit and remodel scenarios where access is limited and standard-length bits fall short.

Key Features

• Aggressive tip geometry for faster cutting through wood framing members
• Non-stick coated flutes promote faster chip ejection and reduce binding during long-reach drilling
• Wire-pulling hole at the tip allows cable to be attached and pulled back through the hole in one step
• 3-flat shank prevents the bit from slipping in the chuck during high-torque drilling
• 12-inch length provides extended reach for drilling through deep wall assemblies

Compatibility

Designed for use in standard 3-jaw drill chucks accepting a 3-flat shank; compatible with corded and cordless drills used for bell hanger and low-voltage rough-in work.

Installation Notes

This bit is typically installed and used by licensed electricians, low-voltage technicians, or security system installers performing rough-in wiring. Confirm the drill path is clear of electrical conductors, plumbing, and other utilities before drilling. Follow applicable local building codes and NEC low-voltage wiring guidelines when routing cable through fire-rated assemblies. Wear appropriate eye protection to guard against chip ejection during drilling.
