Product details

The DIN 338 Stepstar metal drill bit set from Heller is a high-quality selection of spiral drill bits specifically designed for processing various metals. With a special cobalt alloy (HSS-Co), these drill bits offer outstanding service life and efficiency. They are ideal for precise drilling without the need for a pilot hole, significantly simplifying the application. The innovative three-flat shank starting from 5 mm ensures that the drill bits are held securely in the chuck, preventing slippage. This is particularly advantageous when used with handheld cordless drills. The set is suitable for a variety of materials, including stainless steel, steel, iron, cast iron, non-ferrous metals, aluminum, as well as wood and plastic, making it a versatile addition to any workshop.

  • High-quality cobalt alloy for maximum service life
  • Accurate drilling without pilot holes
  • Three-flat shank from 5 mm for optimal grip in the chuck
  • Suitable for a variety of materials, including stainless steel and aluminum.
