Diablo 1/4 Inch x 18 Inch Installer Drill Bit for Wood Wire Cable Installation 3-Flat Shank High Performance Long Reach Boring Bit DIB1050

Streamline Your Wiring Projects with Diablo’s High-Performance Extended Reach Installer Bits

The Diablo DIB1050 1/4-Inch x 18-Inch Installer Drill Bit is the professional’s definitive tool for fast, efficient wire and cable installation. Specifically engineered for technicians and electricians, this bit features an ultra-sharp tip that maximizes durability while ensuring perfectly straight holes through clean wood or thick, stacked lumber. The 18-inch extended length provides the critical reach necessary to navigate through deep wall cavities, ceilings, and floors, making it indispensable for complex residential and commercial wiring runs.

To further enhance jobsite productivity, these bits are designed with black oxide coated flutes that prevent debris build-up and facilitate rapid chip evacuation. A specialized small hole integrated directly into the flute allows you to securely attach and pull wires or cables back through the newly drilled hole with zero effort. Built for maximum stability, the 3-flat shank eliminates bit spinning within the drill chuck, providing the high-torque performance required in both corded and cordless drill drivers for demanding installation environments.

Specifications

Pro-Tip: To ensure the easiest cable pull, drill your hole completely and clear the debris with a few back-and-forth passes of the bit. Before withdrawing the bit for the last time, thread your pull-wire through the small hole in the flute; as you pull the bit back out of the wall, your wire will follow through the hole perfectly, saving you time and frustration.
