Metallic Electrodes

Range of Metallic tubular electrodes:

For micro EDM & start hole application available USA make Copper, Brass, Copper Multi-Hole, Brass Multi-Hole $ Tungsten Copper Tubes of various diameters and lengths.

Precision Copper & Brass Single Hole Tubular Electrodes

99.9% pure electrolytic copper tubes of diameter ranging from 0.20mm to 6mm in steps of 0.10mm, & length 400mm. TOLERANCE 0.D., ± 0.005mm to 0.03mm

Copper & Brass Multi-hole (Kor-less) Tubular Electrodes

Copper & Brass Multi-Hole (Kor-Less) Electrodes have a unique design which eliminates the standing spike, normally experienced with tubing type electrodes. Copper & Brass Multi-Hole (Kor-Less) Electrodes are especially useful in “blind” bottom type applications or “through-hole” application.

99.9% Pure Electrolytic Copper & Brass Multi-Hole (Kor-Less) tubes of diameter ranging from 0.50mm to 6mm in steps of 0.10mm, & length 400mm. TOLERANCE 0.D., ± 0.015mm


Solid Copper Electrodes - From 0.20mm to 6mm in step of 0.10mm Length max 400mm

Tungsten Copper Tubular Electrodes:

For EDM drilling of hard metals like carbides or heat-treated metals. Diameter available 0.50mm to 6mm, in step of 0.10mm and length 177.8 mm. Tolerance 0.D. ± 0.015mm

Solid Tungsten Copper Tubular Electrodes:

For EDM drilling of hard metals like carbides or heat-treated metals. Diameters available 0.50mm to 6mm, in steps of 0.10mm and length 177.8mm. Tolerance 0.D. ± 0.015mm
