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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide tip welded to hardened steel shaft for strength and durability in masonry\u003c\/li\u003e\n\u003cli\u003eCrossbored through the bit body for direct wire pull-through after drilling\u003c\/li\u003e\n\u003cli\u003e3\/8-inch diameter produces a clean passage suitable for most low-voltage and signal cables\u003c\/li\u003e\n\u003cli\u003e18-inch length provides reach through thick concrete and CMU walls\u003c\/li\u003e\n\u003cli\u003eNot intended for use in wood or metal — dedicated masonry application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard rotary hammer or hammer drill chucks accepting 3\/8-inch shank bits for masonry and concrete applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician or low-voltage technician in accordance with applicable NEC requirements.
