Product details

The DIN 338 Stepstar metal drill bit set from Heller is a high-quality selection of drills specifically designed for processing various materials. With a total of 19 pieces, this set offers a comprehensive solution for precise drilling in metal, wood, and plastic. The drills are made from high-quality cobalt steel, ensuring a long service life and durability. Thanks to the special geometry of the drills, pinpoint drilling without pre-drilling is possible, which increases efficiency and accuracy during use. The three-flat shank starting at 5 mm ensures that the drills are held securely in the chuck and prevents slipping, which is particularly advantageous for handheld cordless drills. This set is ideal for professional users as well as DIY enthusiasts who value quality and precision.

  • Made from high-quality cobalt steel for maximum longevity
  • Pinpoint drilling without pre-drilling possible
  • Three-flat shank starting at 5 mm for optimal grip in the chuck
