We have released a catalog for ultra-small diameter super hard discharge machining electrodes with a minimum diameter of φ0.01. These electrodes are used for discharge machining. Unlike electrodes made of copper or copper tungsten, they are made of cemented carbide. Super hard carbide electrodes are used when drilling finer holes straight due to their high hardness.

SANWA CREATION Co.,Ltd.

This is a micro-diameter carbide electrode for electrical discharge machining from Sanwa Creation. Although it is an electrode for electrical discharge machining, it is made of carbide alloy rather than copper or copper-tungsten. In cases where a straight hole needs to be drilled with a finer diameter, electrodes made of high-hardness carbide alloy are used. ■ Material: Carbide alloy 　　　　　　　　　　■ Specification: Minimum diameter φ0.01 and up 　　　■ Step grinding length: 2 mm ■ Outer diameter accuracy: ±0.001 mm 　■ Surface roughness: Ra0.2 µm ■ Shaft dimensions φ2 x 50L (standard) *Dimensions can be custom-made. Please feel free to consult with us.
