Bes bellc3818 Carbide Bellhanger Drill Bit 3/8 X 18 in

Product Description

The BES bellc3818 is a carbide-tipped bellhanger drill bit designed for boring through masonry, stone, and concrete in trade installation work. The carbide tip is welded to a hardened steel shaft, providing the durability needed for repeated use in tough substrate. The bit measures 3/8 inches in diameter and 18 inches in length, giving electricians and low-voltage installers the reach needed to pass through thick walls, block, or concrete assemblies. A crossbore through the bit body allows wire to be threaded and pulled back through the hole immediately after drilling, reducing steps on the job.

This bit is used in residential and commercial electrical, alarm, and low-voltage wiring installations where cables or conductors must pass through concrete, block, brick, or stone walls. The 18-inch length is suited for thick CMU walls and stacked masonry assemblies common in commercial construction. Electricians, alarm technicians, and low-voltage installers reach for bellhanger bits when running wire through masonry without core drilling or conduit sleeves.

Key Features

• Carbide tip welded to hardened steel shaft for strength and durability in masonry
• Crossbored through the bit body for direct wire pull-through after drilling
• 3/8-inch diameter produces a clean passage suitable for most low-voltage and signal cables
• 18-inch length provides reach through thick concrete and CMU walls
• Not intended for use in wood or metal — dedicated masonry application

Compatibility

Designed for use in standard rotary hammer or hammer drill chucks accepting 3/8-inch shank bits for masonry and concrete applications.

Installation Notes

Installation should be performed by a qualified electrician or low-voltage technician in accordance with applicable NEC requirements. Wear appropriate PPE including eye protection when drilling into masonry or concrete. Confirm there are no embedded conduit, rebar, or utilities in the drill path before starting. After drilling, feed wire through the crossbore and retract the bit to pull the wire back through the wall.
