IRWIN 3/8" x 18" Wood Installer Drill Bit with Wire Pulling Hole and 3-Flat Shank for Electrical, Plumbing, and Cable Routing Applications

The Professional Cable Solution: IRWIN Installer Bit for Fast, Clean Wood Boring

The IRWIN 3/8" x 18" Wood Installer Drill Bit is a specialized tool engineered for the demanding task of routing cable and wire through finished walls, ceilings, and floors. This extra-long bit provides the necessary reach (18 inches) to bore through multiple studs or joists, making it indispensable for electricians, low-voltage technicians, and remodelers. The primary time-saving feature is the hole located in the flute, which allows for the cable or wire to be easily attached and pulled back through the bore hole as the bit is withdrawn, streamlining the entire installation process.

Performance and durability are built into every detail. The bit features a robust 3-flatted shank that locks securely into the drill chuck, effectively preventing slippage and maximizing power transfer. The aggressive 82-degree point is designed for fast, smooth drilling into wood without walking or wandering, ensuring accurate hole placement every time. Constructed from high-carbon steel, this installer bit delivers the longevity and reliability required for continuous use across demanding construction and home renovation projects.
