L H Dottie Co BLH5618 Bell Hanger Drill Bit

Product Description

The L H Dottie Co BLH5618 is a bell hanger drill bit designed for boring through wood framing, joists, and structural members during low-voltage wiring and cable routing installations. The bit measures 5/16 inches in diameter and 18 inches in length, giving technicians the reach needed to fish wire through wall cavities and floor assemblies without relocating the drill. Electricians, alarm installers, and low-voltage contractors rely on this bit type when running doorbell, speaker, or communication cable through tight structural bays.

This bit is used in residential and light commercial construction and retrofit work where long-reach boring is required through wood framing. It is well-suited for pre-wire and rough-in stages of electrical and low-voltage installations, particularly when working in stud bays, between floors, or above drop ceilings. The 18-inch length allows single-pass drilling through typical dimensional lumber without an extension.

Key Features

• 5/16-inch diameter sized for standard low-voltage and communication cable routing
• 18-inch length provides extended reach through wall and floor framing
• Bell hanger design engineered for wood-boring applications in structural framing
• Sold individually, one bit per unit

Compatibility

Designed as an OEM-style replacement and standard accessory bit compatible with common 3/8-inch and 1/2-inch chuck corded or cordless drills used in electrical and low-voltage trade work.

Installation Notes

Bell hanger bits are typically used by licensed electricians and low-voltage technicians during rough-in. Before drilling, verify stud and joist locations and check for existing wiring, plumbing, or gas lines within the framing cavity. Follow applicable NEC guidelines for cable routing and protection when passing wires through structural members. Wear appropriate eye protection and secure the workpiece before drilling.
