These EDM Electrodes or EDM Supplies then conduct electricity through them down to the work-piece which is the part that you want to drill a hole into. A shorthand term for this process is called Holepop, Holeburning or Holepopping. Most people call it EDM Drilling or Small Hole EDM.

For almost 15 years now, HOLEPOP.com is the EDM Supply underdog that has sold millions of EDM Electrodes to machine shops that manufacture for many different industries. Such as Medical, Tool and Die, Aerospace, Plastic Injection Molding, Defense, Satellite, and even Consumer products. Everyday we are amazed to find new uses and new applications that our EDM Consumable parts are used for.

To see the different uses and applications please visit our Applications page. HOLEPOP.com specializes in only selling High Precision Brass and Copper tubing.  Brass and Copper is the most common EDM Consumable material because it is able to work the best on most metal types. Brass is best used for Tool Steels, Stainless, Titanium, Carbon, Invar, Aluminums and Work Hardened materials that have been heat treated so they cannot easily be machined. Copper is used best on exotic types of metals such as Tungsten and Carbide, these metals are extremely hard and cannot be machined or drilled through using conventional type drilling, only EDM Drilling.

This tubing has a Single hole or Multi Channel (Coreless) set of holes down through the entire length of the tubing for water to pumped through which is used as a coolant to keep the electrode from getting too hot and warping or melting. This also flushes the burnt and disintegrated material out of the bottom of the hole which allows the EDM Drilling to continue deeper into the work piece, also keeping the hole straight and accurate. These EDM electrodes / tubing are designed specifically certain types of applications and can be viewed on our Products
Page. All of our Products are Guaranteed against any defects and are guaranteed to be within the specified tolerances. They are manufactured using an Extrusion process which is under strict ISO 9001 Guidelines.
