Diablo DAG1130 1" x 7-1/2" High-Speed Auger Bit

Self-Feeding Power. Dual-Cutting Precision. Up to 2X More Holes Per Charge.

The Diablo DAG1130 is engineered to redefine high-speed wood drilling. Featuring a specialized self-feeding screw tip, this 1-inch auger bit pulls itself through the toughest timbers, landscape ties, and pressure-treated lumber with minimal effort. Designed specifically for high-torque cordless drills, the DAG1130 maximizes battery efficiency while delivering clean, burr-free holes in a single pass.

For the professional at The Fastener Group, the DAG1130 is the solution for deep-hole applications. Its dual-cutting edge design slices through wood fibers faster than standard bits, while the wide-flute geometry ensures rapid chip evacuation to prevent clogging and stalling. Whether you are running wire through joists or bolting heavy timbers, the DAG1130 delivers industrial-grade speed and longevity.

Key Features & Professional Benefits:

• Self-Feeding Screw Tip: Effortlessly pulls the bit into the wood, reducing user fatigue and ensuring a consistent feed rate without excessive pressure.
• Dual-Cutting Edges: Produces cleaner, faster holes by shearing wood fibers on both sides of the bit, resulting in a smooth finish with no "break-out."
• Optimized for Cordless Drills: Engineered to require less torque, allowing you to get up to 2X more holes per battery charge compared to standard auger bits.
• Wide-Flute Design: Enhanced chip removal prevents heat buildup and bit stalling, making it the ideal choice for deep-hole drilling in wet or sap-heavy lumber.
• Induction Hardened Steel: Provides superior durability and remains sharp significantly longer than traditional carbon steel bits.
• Quick-Change Hex Shank: Ensures a secure, slip-free grip in all 1/2" drill chucks and impact drivers (high-torque models recommended).
