Irwin IWAX3018 Ship Auger Bit 0.875 Inch Hex Shank

Product Description

The IRWIN IWAX3018 is a ship auger bit from the SPEEDBOR SUPREME series, designed for boring clean, deep holes through wood framing, timbers, and structural lumber. Built from high-speed steel with an oxide coating, this bit delivers controlled cutting performance in demanding jobsite conditions. It features a 0.875-inch hole diameter, a 5-inch flute length, and a 7.5-inch overall length. The standard point type and hex shank make it fast to seat in compatible drill chucks. Electricians, plumbers, and carpenters rely on this type of bit when routing wiring or pipe through structural members where a standard twist bit will not reach deep enough.

The IWAX3018 is suited for residential and light commercial construction and renovation work. Typical applications include drilling through wall plates, floor joists, and ceiling framing to route conduit, pipe, copper tubing, or electrical cable. The hex shank prevents slipping in the chuck under torque load. The 5-inch twist length provides enough depth to penetrate most single framing members in one pass without repositioning.

Key Features

• 0.875-inch cutting diameter for standard framing penetrations
• High-speed steel construction with oxide coating for corrosion resistance and extended bit life
• 5-inch flute length clears chips efficiently during deep boring
• 7.5-inch overall length reaches into tight framing cavities
• Hex shank design locks into drill chucks and quick-change systems to prevent slipping under load
• Standard point type for accurate starting on wood surfaces

Compatibility

Designed as an OEM-style replacement ship auger bit compatible with standard hex-shank drill chucks and quick-change bit holders used in corded and cordless drills.

Installation Notes

Ship auger bits of this type are installed by electricians, plumbers, and carpenters using corded or cordless drills rated for auger-style bits. Confirm the drill chuck accepts a hex shank before use. When boring through framing near electrical wiring or plumbing, de-energize circuits and shut off water supply before drilling to avoid contact. Keep the bit clear of nails and fasteners, as metal contact can chip the cutting edge or cause the bit to grab unexpectedly.
