The Irwin 1789225 is a left-hand drill bit made from high-speed steel, designed for drilling and fastener removal tasks. Left-hand bits are especially useful when you need to extract broken right-hand threaded studs and bolts—a common repair challenge. This bit combines strength, heat resistance, and wear resistance in a single tool that handles demanding drilling applications.

Whether you're a professional tradesperson or a DIY enthusiast tackling home improvement projects, this left-hand drill bit reduces frustration by minimizing bit walk and allowing faster penetration into materials. The 135-degree split point design cuts down on feed pressure, making drilling easier and more efficient while helping prevent work hardening in the material.

Features and Benefits

  • High-Speed Steel Construction: Offers excellent strength, heat resistance, and wear resistance for heavy-duty applications and repeated use.
  • 135-Degree Split Point: Reduces feed pressure and allows easier penetration without work hardening, minimizing bit walk during operation.
  • Black Oxide Finish: Provides corrosion resistance, keeping the bit in top condition even after repeated use and in wet environments.
  • Left-Handed Design: Specifically engineered for extracting broken right-hand threaded fasteners and studs.
  • Screw Extractor Compatible: Can be used with screw extractors for enhanced fastener removal capability.
  • Versatile Materials: Suitable for drilling into mild steel, wood, and plastic.
