Irwin IWAX128PC 8pc Spade Bit Set 3/8 to 1-1/2 in

Product Description

The IRWIN INDUSTRIAL TOOL CO IWAX128PC is an 8-piece pro spade drill bit set built for electricians, plumbers, carpenters, and other trade professionals who need fast, clean through-holes in wood framing, sheeting, and structural members. Each bit measures 6 inches in length and features a 1/4 inch hex shank for use in standard drills and 1/4 inch quick-change adapters. The set spans eight sizes from 3/8 inch up to 1-1/2 inch. A patented Micro Groove cutting edge combined with a double spur design scribes the hole perimeter before material is removed, producing a cleaner bore and reducing vibration at the tool.

This set is suited for residential and light commercial rough-in work where multiple hole sizes are needed in a single job. Electricians running cable and conduit through studs and joists, plumbers boring for pipe runs, and HVAC techs cutting penetrations for duct or refrigerant line sets will find the full size range covers most standard trade applications. The rugged storage case with rubber over-mold construction and sliding latch keeps the set organized and protected on the job site or in a service van.

Installation Notes

Spade bits are installed by trade professionals using corded or cordless drills. Ensure the workpiece is secured before drilling to prevent movement. Keep bits clear of embedded fasteners, which can damage cutting edges. Follow applicable codes such as NEC or IPC when sizing penetrations for electrical or plumbing rough-in work.
