What is a tungsten carbide pin gauge?
In production lines that require high-intensity and high-volume inspection, the wear resistance of gauges directly determines quality control costs and product consistency.
Mihe Precision (MISHUTE) Tungsten Carbide Pin Gauges are made from selected ultra-fine grain cemented carbide, specifically designed to solve the “dimensional drift” problem of traditional white steel pin gauges caused by frequent friction.
Tungsten carbide is known for its extremely high hardness and rigidity. Even when passing through metal workpiece bores over long periods and at high inspection frequencies, its wear rate remains extremely low, ensuring long-term dimensional accuracy and stability.
Our tungsten carbide pin gauges are especially suitable for metal cutting, mold manufacturing, and automated inspection lines. Each gauge is precision ground and polished by Mihe engineers in a 20°C constant-temperature environment and comes with a traceable factory inspection report, making it one of the most durable inspection tools in precision manufacturing.
Key Features
- Exceptional Hardness & Wear Resistance：With a hardness exceeding HV 1500, it is significantly higher than GCr15 bearing steel. When measuring hard materials such as hardened steel and titanium alloys, its surface is highly resistant to scratching and wear, ensuring the long-term reliability of Go/No-Go gauge inspection.
- Superior Dimensional Stability：Cemented carbide has an extremely high elastic modulus and is not easily subject to elastic deformation caused by minor force or temperature fluctuations. This enables it to provide more stable measurement performance than steel gauges in micron-level precision inspection.
-
Precision Lapped Surface Finish：The surface roughness reaches Ra ≤ 0.02 μm. This extremely high level of surface finish not only reduces friction during measurement, but also prevents the adhesion of metal chips, ensuring smooth and highly accurate bore diameter inspection.

FAQ about Tungsten Carbide Pin Gauges
If you require excellent drop resistance and high cost-effectiveness for general operating environments, tungsten carbide is the best choice. If you need anti-magnetic and anti-corrosion properties, or if your measurement environment has significant temperature fluctuations, ceramic pin gauges are the better solution. Both options offer a service life far longer than standard steel gauges.
Tungsten carbide has higher toughness than ceramic, but it can still chip under severe lateral impact. It is recommended to use a handle during operation and avoid using the gauge as a prying or striking tool.
The cost of cemented carbide raw materials and the difficulty of precision grinding are significantly higher than those of bearing steel. However, in the long run, tungsten carbide gauges offer a service life 5–10 times longer than steel gauges, reducing downtime for recalibration and frequent replacement costs. As a result, the overall cost per use is actually lower.
Yes. We have a fully equipped production line supporting custom diameters from 0.1 mm to 30 mm (e.g., 5.012 mm), while maintaining Class X accuracy and fast lead times.
