Irwin IWAX236PC Spade Drill Bit Set 6 Pc Hss

Product Description

The IRWIN IWAX236PC is a 6-piece spade drill bit set designed for boring clean holes in wood and wood-composite materials. The set spans six bit sizes ranging from 0.5 inches to 1.25 inches, covering the most common rough-in and finish hole diameters used in residential and light commercial work. All bits are manufactured from high-speed steel with a bright, uncoated finish. Spade bits in this range are a standard tool for electricians and plumbers routing cable or pipe through framing, as well as carpenters and general contractors working structural or finish applications.

This set is suited for residential framing, rough-in electrical, and plumbing applications where drilling through wood studs, plates, and joists is required. The six-size progression lets a technician work through a range of conduit knockouts, cable pass-throughs, or pipe bores without swapping between separate sets. The uncoated high-speed steel construction handles standard softwood and hardwood framing at typical drill speeds without issue.

Key Features

• 6-piece set covering 0.5 inches through 1.25 inches in six incremental sizes
• High-speed steel construction for durability in wood and wood-composite materials
• Bright, uncoated finish — no coating to chip or flake during high-friction boring
• Spade-style geometry optimized for fast, aggressive wood drilling
• Inch-system sizing aligns with standard NEC and IPC rough-in hole requirements

Compatibility

Designed for use in standard 3-jaw or keyless drill chucks accepting spade bit shanks. Suitable for corded or cordless drills used in wood drilling applications.

Installation Notes

Spade bits are installed and removed by hand in a standard drill chuck — no special tools required. Electricians and plumbers should confirm hole placement meets applicable NEC or IPC clearance requirements before drilling through structural members. Keep work area clear of nails or embedded fasteners, which can damage the bit tip or cause binding. Secure the workpiece before drilling to prevent kick or splitting.
