High-Quality EDM Electrode Tubes (Brass & Copper)
EDM tube is a consumable for EDM drilling machines, also known as: EDM copper tube, EDM brass tube, EDM drilling tube, EDM electrode tube.
Our EDM tubes are widely used in high-speed EDM small-hole drilling machining, especially for:
Deep hole drilling
Precision micro-hole machining
Mold manufacturing
Aerospace components
Tool & die applications
They provide stable spark performance, smooth chip removal, and consistent hole accuracy.
