EDM Drilling Tubes and Accessories

SST offers a broad range of high-quality tubes in both single channel and multichannel design.  These are available in copper and brass and come in a wide variety of diameters, including half sizes. 

Single channel:  SST’s single-hole tubes are used primarily to start holes in the workpiece. They offer superior, consistent quality due to how they are drawn with a die.

Multi-channel:  The design of our multichannel, “I-type” two-channel design provides overall consistent wear on the tubes.
