Lenox 145470081416 Auger Drill Bit 7/8 Inch 18 Inch

Product Description

The LENOX 145470081416 is a ship-type auger drill bit designed for boring through wood, including nail-embedded lumber common in remodel and rough-in work. It measures 7/8 inch in drill diameter with an 18-inch overall length and a 12-inch twist flute, giving tradespeople the reach needed for drilling through wall plates, joists, and framing members. The bit is constructed from bi-metal with a high-speed steel cutting edge, which increases wear resistance when the edge contacts embedded fasteners. A parabolic screw tip pulls the bit through material with reduced effort and can be resharpened to extend service life. The 1/2-inch shank fits standard chuck sizes used by electricians, plumbers, and HVAC technicians for wire and pipe routing.

This auger bit is suited for residential and light commercial construction and service work where long-reach boring is required. Typical applications include drilling through wood framing for conduit, drain lines, refrigerant line sets, or low-voltage wiring runs. The 18-inch length allows single-pass drilling through double top plates or thick structural members without requiring extensions. It is sold individually and is appropriate for any trade requiring through-framing penetrations.

Key Features

• 7/8-inch drill diameter with 18-inch overall length for deep single-pass boring
• High-speed steel cutting edge resists wear in nail-embedded wood
• Bi-metal construction balances toughness and cutting performance
• Parabolic screw tip pulls the bit through material quickly with less applied force
• 12-inch twist flute length for efficient chip evacuation
• Resharpenable design extends usable service life

Compatibility

Designed for use in any 1/2-inch keyed or keyless drill chuck. Suitable for boring through softwood, hardwood, and nail-embedded wood framing in residential and commercial construction applications.

Installation Notes

This bit is installed by electricians, plumbers, and HVAC technicians for routing penetrations through wood framing. Confirm the chuck is fully tightened before operation and verify there are no live conductors or pressurized lines in the drilling path before starting. Reduce feed pressure when the tip contacts a nail or knot to avoid bit deflection or chuck slippage. The bit can be resharpened with a file or bench grinder when cutting performance decreases.
