It's a pin gauge thinner than a hair! A tiny pin gauge with a diameter of 0.01 millimeters!

The "High Precision Small Diameter Pin Gauge for Inner Diameter Measurement" is a carbide pin gauge that enables accurate inner diameter measurements on the micron order. 【Features】 ○ The ultra-precision grade can be used as a master pin gauge. ○ Custom sizes can be manufactured with an outer diameter (φD) of 0.1 to 10mm and a total length of 40 to 60mm. ○ Sizes from φ6.001 to φ10.000 can be made to order. ○ Can also be manufactured from zirconia material. 【Specifications】 [Ultra Precision Grade] ○ Length: 40 / 50 ○ Tolerance: 0.001 ○ Allowable Tolerance: ±0.3μm ○ Roundness: 0.3μm ○ Diameter Variation: 0.3μm ○ Surface Roughness: 0.05μmRa ○ Material: Carbide [Precision Grade] ○ Length: 40 ○ Tolerance: 0.001 ○ Allowable Tolerance: ±0.5μm ○ Roundness: 0.5μm ○ Diameter Variation: 0.5μm ○ Surface Roughness: 0.1μmRa ○ Material: Carbide [Standard Grade] ○ Length: 40 ○ Tolerance: 0.001 ○ Allowable Tolerance: ±1.0μm ○ Roundness: 0.8μm ○ Diameter Variation: 0.8μm ○ Surface Roughness: 0.2μmRa ○ Material: Carbide

Industry-leading, ultra-fine pin gauges thinner than a hair! We manufacture from a minimum diameter of φ0.01 millimeters! Calibration certificates and traceability diagrams can be issued as needed. If you specify your desired dimensions and accuracy, we will provide a quote. These are used for measuring the inner diameter of high-precision ultra-small holes and as master gauges for calibrating measuring instruments. They can also be used as punch pins for small diameter hole punching or as electrode materials for electrical discharge machining. We offer both "integrated type" and "holder (handle) type."

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.
