The Irwin 81159ZR #59 Jobber Drill Bit is a precision wire gauge drill bit made from high-speed M-2 steel, designed to drill exact-sized holes for tapping and other demanding applications. This bit creates non-fractional sized holes where standard fractional sizes won't work, making it essential for automotive repair, maintenance operations (MRO), and precision drilling tasks in both portable drills and stationary drill presses.
High-speed steel construction resists heat and wear, allowing you to work through tough materials without premature dulling. The 118° tip geometry delivers optimal cutting action for smooth drilling in wood, metal, and plastic.
Features and Benefits
- High-Speed M-2 Steel: Provides exceptional strength, heat resistance, and wear resistance for extended tool life and consistent drilling performance across multiple applications.
- 118° Tip Geometry: The standard point angle delivers optimal cutting action and smooth drilling in wood, metal, and plastic materials.
- Jobber Length Design: The 1-5/8 inch length balances drilling depth capability with easy maneuverability and is suitable for a variety of drilling applications.
- Exact Size Drilling: Creates precise #59 (0.041 inch diameter) holes for tapping and applications where non-fractional sizing is critical.
- Straight Shank: Straight shank design for easy compatibility with standard drill chucks.
- Individual Unit: Sold as a single bit, allowing you to replace or stock specific sizes as needed without purchasing full sets.
