Irwin IWAX3019 Ship Auger Bit 1 Inch Hex Shank Hss

Product Description

The IRWIN IWAX3019 is a ship auger bit from the SPEEDBOR SUPREME series, designed for boring large, clean holes through wood framing, timber, and structural lumber. Built from high-speed steel (HSS) with an oxide coating, this bit delivers durability under repeated use in demanding jobsite conditions. It features a 1-inch hole diameter, a 7.5-inch overall length, and a 5-inch flute length that clears chips efficiently during deep boring. The hex shank provides a secure, slip-resistant grip in standard drill chucks and impact-compatible holders. Licensed electricians, plumbers, and general contractors commonly use ship auger bits when running conduit, pipe, or cable through wood framing members.

The IWAX3019 is suited for residential and light commercial construction and renovation work. Its ship auger bit design excels in through-boring applications where a standard twist bit or spade bit would struggle, particularly in thick dimensional lumber, engineered wood, or stacked framing. The standard point type ensures accurate entry without requiring a pilot hole. This bit is typically deployed by electricians fishing wire through joists and studs, plumbers routing supply or drain lines, and HVAC installers running refrigerant line sets or low-voltage control wiring.

Key Features

• 1-inch hole diameter for full-size bore in a single pass through framing lumber
• High-speed steel construction with oxide coating for corrosion resistance and extended edge life
• 5-inch flute length promotes efficient chip ejection during deep cuts
• 7.5-inch overall length reaches into tight framing cavities without extensions
• Hex shank seats securely in drill chucks and compatible hex-drive holders
• Standard point type for accurate, no-wander entry into wood surfaces

Compatibility

Designed as an OEM-style replacement and general-use ship auger bit compatible with standard 3-jaw drill chucks and hex-drive drill systems accepting a hex shank.

Installation Notes

Ship auger bits are installed by electricians, plumbers, and HVAC technicians working on framing rough-in. Always disconnect power at the breaker or shut off water supply before boring near existing wiring or piping. Use a drill with adequate torque and a firm two-hand grip, as large-diameter bits in wood can produce significant kickback if the bit binds. Inspect the bit for wear or damage before each use and do not force a dull bit through dense material.
