Key Features

  • Premium High-Speed Steel (HSS) Construction: Manufactured from durable high-speed steel for excellent hardness, toughness, and heat resistance, ensuring an extended tool life in rigorous use.
  • Advanced Black & Gold Surface Treatment: This functional coating reduces friction, improves chip flow, and enhances corrosion resistance, contributing to smoother drilling operations and increased bit durability.
  • 135-Degree Split Point Tip: Engineered for fast, clean starts and reduced "walking" on the workpiece, eliminating the need for center punching in most applications and improving overall accuracy.
  • Self-Centering Design: The 135-degree split point geometry allows the drill bit to start cutting immediately upon contact, requiring less thrust pressure and enhancing stability, especially in harder materials.
  • Jobber Length Design: Provides a versatile balance of reach and rigidity, making it suitable for a broad range of general-purpose drilling tasks in both shop and field environments.

Applications

This Tru Cut HDC.125 drill bit is ideal for professional technicians and mechanics working across various sectors. It excels in drilling common materials found in automotive repair, metal fabrication, and general industrial maintenance. Common use cases include creating pilot holes, drilling out broken bolts, or preparing surfaces for fasteners in materials such as steel, aluminum, cast iron, brass, and other machinable alloys. Its robust construction and precise cutting geometry make it suitable for use with hand-held drills, drill presses, and light machining applications.
