Product details

The HSS metal twist drill from Heller is a precise tool specifically designed for machining metal. With a diameter of 4 mm and an overall length of 75 mm, this drill offers an optimal combination of stability and efficiency. The drill is made from high-quality HSS (High-Speed Steel), making it particularly durable and resistant to wear. The rolled surface treatment enhances cutting performance and reduces friction during the drilling process. The 118-degree point angle allows for quick and precise penetration into the material, while the cylindrical shank ensures easy handling and compatibility with standard drills. This drill is ideal for use with various types of metal, including steel and iron, and is suitable for both professional and hobby applications.

  • Made from high-quality HSS for increased durability
  • Rolled surface treatment for improved cutting performance
  • 118-degree point angle for precise penetration into metal
  • Suitable for various types of metal, including steel and iron.
