Irwin 49914 Solid Center Auger Bit 7/8 Inch

Product Description

The IRWIN INDUSTRIAL TOOL CO 49914 is a 7/8-inch solid center auger bit engineered for boring clean, accurate holes in wood. The solid center construction provides extra rigidity during heavy-duty boring applications. With a 4.5-inch twist length and 7.5-inch overall length, this bit is suited for framing, rough-in work, and other through-bore tasks where straight, consistent holes are required. The full-length heat-treated steel body resists bending under load and strengthens the twist at the point of greatest strain, making it a reliable choice for professional carpenters, electricians, and plumbers boring through structural lumber.

This auger bit is designed for use in wood boring applications across residential and light commercial construction. Wide lands keep the bit tracking straight as it advances through the material. The flutes are ground behind the lands to channel chips inward and away from the outside diameter, reducing friction and producing a faster, cleaner cut. The coarse screw point pulls the bit into both hard and soft woods without requiring excessive feed pressure. It is packaged in a pouch and sold in a package quantity of six, making it practical for job-site stocking.

Key Features

• Solid center construction provides extra rigidity for heavy-duty boring
• Full-length heat-treated body resists bending and strengthens the twist under strain
• Wide lands keep the bit straight throughout the bore
• Flutes ground behind the lands funnel chips away from the outside diameter for a faster, cleaner cut
• Single spur cutting edge scribes the hole circumference for a smoother finish
• Coarse screw point for fast self-feeding in hard and soft woods

Compatibility

Designed as an OEM-style replacement or standard-stock auger bit for use with brace-style or hex-shank compatible boring tools in wood framing and rough-in applications.

Installation Notes

Installation of this bit is typically performed by carpenters, electricians, or plumbers during rough-in framing stages. Ensure the bit is fully seated and secured in the tool chuck before operation. Avoid forcing the bit through knots or embedded fasteners, which can cause deflection or tip damage. Disconnect power to any adjacent electrical circuits before boring through walls or framing members that may conceal wiring.
