Lenox 1456207A1716 Ship Auger Bit 1-1/16 in Bi-metal

Product Description

The LENOX 1456207A1716 is a ship auger bit built for boring large-diameter holes through wood framing, timber, and similar materials. It measures 1-1/16 inches in cutting diameter with a 7-1/2 inch overall length and a 4 inch twist section. The 7/16 inch hex shank provides positive engagement in most standard drill chucks and impact drivers equipped for hex-shank tooling. Constructed from bi-metal with a high speed steel cutting edge, the bit resists wear and handles demanding drilling applications. A screw-point tip draws the bit into the material without the need for a pilot hole, improving feed control and reducing blowout on entry.

Ship auger bits are used by carpenters, electricians, plumbers, and HVAC installers when boring through structural lumber, wall plates, floor joists, and similar wood substrates. This bit suits residential and light commercial rough-in work where large clearance holes are needed for pipe, conduit, or wire runs. The 7-1/2 inch overall length fits standard drill applications without requiring an extension. The single cutting edge design keeps the cut clean and consistent in solid wood and engineered lumber.

Key Features

• 1-1/16 inch cutting diameter for large clearance holes through framing and timber
• Bi-metal construction with high speed steel cutting edge for extended wear resistance
• Screw-point tip draws the bit into the workpiece for controlled, consistent feed
• 7/16 inch hex shank seats securely in standard hex-chuck drills and compatible drivers
• 4 inch twist length efficiently clears chips during deep boring passes
• Bright uncoated finish — no coating buildup to interfere with chip evacuation

Compatibility

Designed for use in drills and drivers accepting a 7/16 inch hex shank. Extension capability is not supported for this bit. Suitable for drilling through softwood, hardwood, and engineered lumber in residential and commercial rough-in applications.

Installation Notes

Ship auger bits are typically used by carpenters, electricians, and plumbers during rough-in framing work. Secure the workpiece before drilling and confirm the drill chuck is properly seated on the hex shank before beginning a bore. Wear appropriate eye protection when operating large-diameter auger bits, as chip ejection is significant. Do not force feed the bit — allow the screw point to draw the bit at its natural rate to avoid binding or bit breakage.
