Dewalt DW1665 Auger Bit 5/8 Inch Short

Product Description

The DEWALT DW1665 is a 5/8-inch short power ship auger bit designed for fast, aggressive boring through wood framing, lumber, and rough construction materials. Ship auger bits use a single-spur, open-flute design that clears chips efficiently and reduces clogging during deep or repeated bores. The short configuration gives electricians, plumbers, and HVAC installers better control in tight spaces where a full-length auger bit would not fit. This bit weighs 0.11 pounds and is sold individually. It is intended for use with a corded or heavy-duty cordless drill in professional trade applications.

The DW1665 is well suited for drilling through wall plates, joists, and studs during rough-in work. Electricians use ship auger bits to run conduit and wire through framing. Plumbers rely on them for drain and supply line penetrations. HVAC techs use them for refrigerant line sets and low-voltage control wiring pass-throughs. The short length makes it especially practical in confined wall cavities, crawl spaces, and mechanical chases where swing room is limited.

Key Features

• 5/8-inch bore diameter for standard trade rough-in applications
• Short auger length improves control in confined framing cavities
• Open-flute ship auger design clears chips and reduces clogging
• Lightweight at 0.11 pounds for extended overhead or confined-space use
• Single-unit packaging — sold as each

Compatibility

Designed as a replacement or supplemental ship auger bit compatible with standard hex or round-shank drill chucks used in professional corded and cordless drills. Verify shank type against your drill chuck before installation.

Installation Notes

This bit is installed and operated by a journeyman electrician, plumber, or HVAC technician as part of rough-in drilling work. Ensure the drill is powered off and the bit is fully seated in the chuck before use. Wear appropriate eye protection when boring through framing lumber, as chip ejection is aggressive with open-flute auger designs. Follow applicable building codes, including NEC, IPC, and IFGC requirements, when routing penetrations through fire-rated assemblies.
