Dottie BLH3612 3/16 X12 Bell Hanger Drill Bit

Make quick, precise cable passes through studs and headers with the Dottie BLH3612 3/16 x12 bell hanger drill bit — engineered for professional security, surveillance and low-voltage installers. This bell hanger drill bit creates consistent 3/16" (0.19") holes ideal for running small-gauge wires, coax, and thin networking conductors while minimizing rework and cable snags. Constructed from high carbon steel, the BLH3612 resists wear on wood and metal and holds its aggressive point for fast starts and smooth penetration.

The tapered flute geometry promotes rapid chip removal to prevent clogging and binding, so technicians spend less time cleaning bits and more time completing monitoring and cabling tasks. At 12" length, it reaches through studs and headers for efficient fishing of wires during surveillance camera, security panel, and low-voltage network installs. Durable, reliable and purpose-built, this Dottie bell hanger bit reduces friction, speeds installs and helps maintain neat, professional cable runs. Add the BLH3612 to your toolkit to streamline security and surveillance cabling operations — order today.
