1 Inch x 12 Inch Wood Auger Drill Bit for Tree Stump Drilling | Carbon Steel, Hex Shank, Self-Feeding, Lumber & Tree Stump Drilling

The self-feeding screw point is the key to its performance. Unlike standard drill bits that require firm pressure to start, this auger bit pulls itself into the workpiece the moment it makes contact. The coarse-thread screw tip bites into wood fibers instantly, providing positive traction that eliminates walking and ensures accurate hole placement. Once engaged, the single-spur cutting edge takes over. This design feature scores the circumference of the hole before material is removed, creating a clean, well-defined edge that minimizes tear-out and splintering. The result is smooth entry and exit holes with a clean finish, whether working with soft pine or dense hardwoods like oak and maple. The deep spiral flutes are engineered for rapid chip evacuation. As the bit advances, wood chips are channeled up and out of the hole, preventing clogging that can lead to overheating, binding, or stalled drills. This efficient chip flow allows for faster drilling speeds and longer continuous operation without the need to frequently back out the bit to clear debris. This 1 inch x 12 inch auger bit is sized for a wide range of tasks. It is ideal for drilling through wall studs to run electrical wire or plumbing, creating mounting holes for floating shelf brackets, boring deep holes in lumber for joinery, and even drilling into tree stumps for removal applications. The 12-inch length provides the reach needed for these tasks while maintaining enough rigidity for precision work. Product Specifications: Bit Type: Wood Auger Drill Bit Diameter: 1 inch (26 mm) Overall Length: 12 inches (300 mm) Shank Type: Hex shank, 9 mm Material: High Carbon Steel Features: Self-feeding screw point, single-spur cutting edge, deep spiral flutes Applications: Softwood, hardwood, lumber, plywood, MDF, railroad ties, landscape timber, floating shelf installation, wiring through studs, tree stump drilling

• Self feeding screw point for fast starts: The sharp, coarse-thread screw point pulls the bit into the wood with minimal pressure, eliminating the need for a pilot hole. Starts instantly on contact without walking or skidding
• Precision ground for smooth holes: The single-spur cutting edge scores the hole circumference before the cutting edge removes material, resulting in clean entry and exit holes with minimal splintering—even in hardwoods
• Efficient chip removal design: Deep, wide flutes allow wood chips to flow freely out of the hole during drilling, reducing binding and heat buildup. This design enables faster drilling and longer continuous operation
• Heavy duty high carbon steel: Forged from high carbon steel with precision heat treatment, this auger bit maintains a sharp edge through repeated use. The solid center construction provides stability for straight, accurate holes
• Versatile 1 inch x 12 inch size: Well-suited for drilling through studs for wiring, installing hidden floating shelf brackets, boring deep holes in lumber, and tackling tree stumps. Hex shank prevents spinning in the chuck
