The IRWIN IR3041001 is a wood boring bit designed for drilling clean, precise holes through wood framing, sheeting, and dimensional lumber. At 1/2 inch in diameter and 6 inches in length, this bit handles standard rough-in boring tasks where electricians, plumbers, and HVAC installers need to pass conduit, pipe, or flex duct through wood members. The 6-inch length provides enough reach to clear typical stud and joist depths without extensions. It is a single-piece unit sold individually and is suited for use with standard corded or cordless drill drivers in trade installation work.
This bit sees regular use in residential and light commercial construction where tradespeople bore through wall studs, floor joists, and roof framing for utility rough-in. Electricians use it for wire and conduit runs. Plumbers use it for supply and drain line penetrations. HVAC technicians use it for low-voltage control wire and small-diameter refrigerant line routing. The 1/2-inch diameter is a common size for 1/2-inch conduit knockouts and PEX supply runs.
Designed as an OEM-style replacement and standard-use boring bit compatible with 3/8-inch or larger keyed and keyless drill chucks accepting round or hex-shank wood boring bits.
This bit is typically installed and used by licensed electricians, plumbers, and mechanical contractors during rough-in phases. Always verify that no live wires, energized conductors, or pressurized lines are present behind the boring surface before drilling. Consult NEC, IPC, or IFGC clearance requirements when boring near structural members. Use appropriate bit guards or depth stops when boring at angles to prevent grab and kickback.
