EDM Carbide Contact Inserts

EDM carbide inserts are removable cutting tips that help to improve your EDM's performance. These EDM power feed contacts promote faster machining and result in more refined product finishes. Because carbide inserts are not brazed or welded to the tool body, they can be removed and replaced. They are usually indexable, meaning they can be exchanged, rotated, or flipped without disturbing the tool.

Why Choose Carbide Inserts for EDMs?

Carbide, also called hard metal, is a broad term for a class of chemical compounds in which carbon is combined with a metallic element to create an exceptionally strong material. Carbide is a popular manufacturing material because it offers beneficial characteristics, including high hardness, strength, and resistance to wear and corrosion. Because of these advanced properties, carbide is ideal for EDM inserts.

Benefits of EDM Carbide Points

Carbide inserts for EDMs are made from a mixture of tungsten carbide and other materials cemented together by using cobalt to bind them, resulting in a highly wear-resistant, durable insert. Creating contacts using wire-cut carbide provides a range of benefits, including:
  • Higher cutting temperatures
  • Faster machining
  • Better finishes
  • Closer tolerances
  • Longer tool life
