Irwin 1890711 Installer Drill Bit 1/2x18 Alloy Steel

Product Description

The IRWIN INDUSTRIAL TOOL CO 1890711 is a long installer drill bit designed for fast, clean boring through wood, plaster, and metal lath during wire installation work. Measuring 0.5 inches in diameter and 18 inches in length, the bit features a degree point geometry that bites quickly into material without excessive force. A hole in the flute allows the installer to thread wire directly through the bit and pull it back through the drilled path in one motion. Constructed from premium alloy steel, this bit is built to hold up through repeated boring in mixed materials common in residential and light commercial rough-in work. It is packaged and sold in a 10-count pouch.

This installer bit is suited for electricians, low-voltage technicians, and telecom installers running small-gauge wire through finished and unfinished assemblies. Typical applications include routing wire for telephone lines, cable TV, computer networking, and security systems through walls, ceilings, and floors. The long 18-inch shank provides reach through standard framing and cavity depths without the need for extension accessories. The flute-hole wire-pulling feature reduces the number of steps required to complete a wire pull, making it a practical choice for high-volume installation work.

Installation Notes

Installation should be performed by a qualified electrician or low-voltage technician in accordance with applicable NEC requirements for the wire type being routed.

Use appropriate personal protective equipment when boring through plaster or metal lath. Thread wire through the flute hole before withdrawing the bit to complete the pull in a single motion.
