Step drill bits (also known as "Christmas tree" bits) with a chip groove are designed for industrial drilling in thin materials, enlarging existing holes, smoothing edges, and creating several different holes with one tool. They are suitable for use on steel sheets, non-ferrous metals, plastics, and stainless steel (in HSSCo version).

Advantages:

  • One tool allows for the creation of several holes of different sizes.
  • Ideal for limited access to the drilled surface and large hole diameters.
  • Long product lifespan.
  • Industrial quality.

Applications: For alloy and non-alloy steels, cast steel, gray and ductile cast iron, sintered metal powders, alpaca, graphite, non-ferrous metals, plastics, as well as stainless and acid-resistant steel (step drill bits in cobalt version).
