Stewart Fastener 16SA Ship Auger Bit 1x18

Product Description

The STEWART FASTENER 16SA is a ship auger bit designed for boring deep, clean holes through wood and wood-composite materials. Measuring 1 inch in diameter and 18 inches in length, this bit is built for applications that require extended reach beyond what standard auger bits provide. The 16SA is used by carpenters, electricians, plumbers, and general contractors who need to drill through framing members, joists, or structural wood to route pipe, conduit, or cable. The elongated shaft delivers the depth needed for through-framing work in a single pass.

This ship auger bit is suited for residential and commercial construction and renovation work. Its 18-inch length makes it particularly useful for drilling through double or triple framing members, thick beams, or stacked lumber where shorter bits cannot reach. It is commonly used in rough-in work for plumbing drain lines, electrical rough-in through framing, and HVAC flex-duct or pipe penetrations through wood structure. The 1-inch diameter accommodates a range of pipe and conduit sizes used in standard trade rough-in applications.

Key Features

• 1-inch cutting diameter for standard trade rough-in hole sizing
• 18-inch overall length for deep-reach boring through thick framing
• Ship auger design provides clean entry and efficient chip clearing in wood
• Compatible with standard hex-shank or spade-tip bit drivers and heavy-duty drills
• Catalog number 16SA for direct OEM and distributor ordering

Compatibility

Designed for use with heavy-duty corded drills and right-angle drill drivers that accept standard ship auger bit shanks. Suitable for softwood, hardwood, and engineered lumber applications typical in residential and commercial framing.

Installation Notes

Ship auger bits of this length are typically operated with a heavy-duty right-angle drill or high-torque corded drill to maintain control through deep cuts. Ensure the workpiece is secured before drilling to prevent kickback. When drilling through framing for plumbing or electrical rough-in, follow applicable code requirements for hole placement and edge-distance minimums per the IPC, IFGC, or NEC as appropriate to the trade. Keep the bit clear of embedded fasteners or metal connectors before starting the bore.
