This pin gauge is made from cemented carbide and makes it possible to accurately measure inside diameters down to the micron order.
The ultra-precision class can be used as a master pin gauge.
It is possible to make them to the desired size ranging from φ0.1 mm to 10 mm for the outer diameter (φD), and from 40 to 60 mm in overall length.
“Calibration certification” and “traceability system diagrams” can be issued as necessary (a separate fee is required).
If we receive your desired measurements or precision, we will calculate an estimate.
Please feel free to consult with us.


♦Super precision grade can be used as a master pin gauge.
ØOutside diameter (φD) 0.1 to 10mm, total length 40 to 60mm can be manufactured in your desired size.
φ6.001 to φ10.000 can be made by individual order.
Material: Zirconia material is available in addition to cemented carbide.
