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.
