Fast Hole EDM Services - Small Hole EDM Drilling

Used for the wire EDM process, fast hole EDM drilling was designed for producing fast, accurate multiple small, holes - start holes for wire EDM operations. Ramtec employs this combination of fast hole edm and wire electrical discharge machining (EDM) because it is often more economical to use for hardened materials.

Small holes that were once almost impossible to drill by conventional machine tools are now being performed with ease. with the capability of drilling through virtually any material. It is conceptually similar to sinker EDM, but the electrode is a rotating tube conveying a pressurized jet of dielectric fluid. Fast hole drilling is particularly advantageous when drilling holes on curved or angled surfaces as the electrode does not need to exert any pressure on the surface.

Various grades & sizes that are pre-hardened, is always in-stock to ensure smooth workflow for us and our customers. If you need a broken die or mold part repaired or replaced quickly.

On-time delivery is assured and rush orders delivered within 24 hours, if necessary.
