Irwin Industrial Tool Co 1890709 Installer Drill Bit

Product Description

The IRWIN INDUSTRIAL TOOL CO 1890709 is a long installer drill bit designed for boring through structural materials and pulling wire in a single pass. Built from alloy steel, it measures 3/8 inch in diameter and 18 inches in length, giving technicians the reach needed to work through wall cavities, ceiling assemblies, and floor structures. A degree point geometry accelerates entry into wood, plaster, and metal lath without requiring excessive pressure. The flute includes a wire-pulling hole, allowing the installer to feed wire back through the bore immediately after drilling. Electricians, low-voltage technicians, and security system installers rely on this type of bit for clean, efficient rough-in work.

This bit is suited for residential and light commercial installation work where small-diameter wire must be routed through framed walls, finished ceilings, or subfloor assemblies. Typical applications include telephone wiring, cable television runs, structured network cabling, and security system wire installation. The 18-inch shaft length provides access through standard framing dimensions without requiring a flex shaft extension in most single-stud scenarios. The package quantity is 10 units per package.

Installation Notes

This bit is typically installed and used by licensed electricians, low-voltage technicians, and security system installers working under applicable local codes. Confirm that utilities including electrical wiring, plumbing, and gas lines are located and avoided before boring into walls, ceilings, or floors. Eye protection should be worn during drilling operations, particularly when boring through plaster or metal lath. Inspect the bit for wear or damage before each use and replace if the point or flute shows deformation.
