L H Dottie Co 1816 Ship Auger Bit 1x18 Inch

Product Description

The L H Dottie Co 1816 is a ship auger bit designed for boring large-diameter holes through wood framing, timbers, and structural members. The 1-inch cutting diameter and 18-inch overall length give electricians, plumbers, and HVAC technicians the reach needed to drive wire, conduit, or pipe through deep framing bays and headers. Ship auger bits use a single-spur, single-flute design that pulls aggressively through dense or wet lumber without jamming. This bit is sold as a single unit and is a standard production tool on rough-in jobs where long-reach boring is required.

This bit is used in residential and light commercial rough-in work where trade professionals need to penetrate multiple studs, plates, or joists in a single pass. Electricians use it for wire chases, plumbers for supply and drain penetrations, and HVAC installers for low-voltage control wiring runs. The 18-inch length is particularly useful when clearance for the drill motor is limited and the full depth of a framing member must be reached.

Key Features

• 1-inch cutting diameter for standard trade rough-in hole sizes
• 18-inch length provides extended reach through deep framing assemblies
• Ship auger flute design clears chips and reduces binding in wood
• Single-unit packaging for individual tool replacement or kit supplementing

Compatibility

Designed as a standard hex-shank or round-shank ship auger bit compatible with corded and cordless drill drivers and right-angle drills commonly used in electrical, plumbing, and HVAC rough-in applications.

Installation Notes

Ship auger bits are installed and operated by licensed electricians, plumbers, and HVAC technicians during rough-in framing work. Secure the bit firmly in the drill chuck before operation and confirm the shank is fully seated to prevent slippage under load. When boring near structural members, follow applicable building codes regarding minimum edge distances for notching and boring. Always verify that no existing wiring, piping, or structural fasteners are present in the boring path before drilling.
