This is a discharge machining electrode with an extremely small diameter! Minimum diameter φ0.01, made of carbide.
This is a carbide electrode material with a minimum diameter of φ0.01, used for electrical discharge machining. A high-hardness carbide electrode is used when drilling straighter, narrower holes.
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. It is rare for carbide alloy to be used as electrode material, but there are cases where carbide electrodes with high hardness are employed when drilling finer holes straight. ■ Material: Carbide alloy ■ Specifications: Minimum diameter φ0.01 ■ Step length: 2 mm ■ Outer diameter precision: ±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.

Applications/Examples of results
Compared to copper and copper alloys commonly used as electrode materials for conventional electrical discharge machining, cemented carbide cannot be said to have good electrical conductivity. However, leveraging the extremely high hardness of cemented carbide (around HRA90), we have developed electrical discharge machining electrodes for ultra-small diameter holes to meet the demand for drilling straighter and finer holes.
