Start-hole EDM is a fast and economical process for machining metal. Copper, brass, or carbide electrodes remove material by means of electrical impulses. Start hole drilling is used as preparation for fine wire or wire erosion work as well as for shooting precise and small range holes with a minimum diameter of only 0.10 mm. These holes can be made in hardened materials, hard metal, and other electroconductive materials. If you are looking for a particularly economical process to produce drill holes in very thin or very thick materials, we’re your competent partner.
