EDM Guides

Precision EDM Guides for High-Performance Machining

Erodex is a trusted supplier of EDM guides to manufacturers in the UK and around the world. Whether you’re performing Fast Hole Electrical Discharge Machining (EDM) or working on critical aerospace and gas turbine components, our precision-engineered guides provide the alignment, durability, and performance required for the most demanding applications.

We specialise in ceramic single-point guides, support sleeves, and custom EDM guide solutions, designed to maximise accuracy, reduce wear, and support continuous, high-speed electrode operation.

What Are EDM Guides?

EDM guides are precision components used to align and support EDM tubing and electrodes during machining. Most commonly used in Fast Hole EDM, these guides ensure the electrode remains true throughout the drilling process, reducing vibration, tool deflection, and wear.

Made from high-performance ceramics, Erodex guides offer long service life, outstanding thermal resistance, and consistent, repeatable machining results.
