EDM Carbide Inserts

EDM carbide inserts are removable cutting tips that help to improve your EDM machine. These EDM power feed contacts promote faster machining and better finishes on the products. They are not brazed or welded to the tool body, so they can be removed. They are usually indexable, meaning that they can be exchanged, rotated, or flipped without disturbing the tool.
The EDM power feed contacts and wire cut carbide inserts are designed to produce high quality, strong products that typical EDM equipment can’t achieve. McWilliams carries a variety of contacts for your wire EDM machine from many popular brands, including Japax and Sodick.

What is Carbide?

Carbide, also called hard metal, is a popular manufacturing material because it offers beneficial characteristics. With its wear-resistance and superior strength, carbide is used for saws, drills, end mills, insert cutters and other machine parts.
Inserts are made from a mixture of tungsten carbide and other materials that have been cemented together by using cobalt to bind them together. Creating contacts using wire cut carbide provides a range of benefits. These include:
  • Higher cutting temperatures
  • Faster machining
  • Better finishes
  • Closer tolerances
  • Longer tool life
