- Can be used as accuracy inspection master for measurement equipment, inspection equipment etc.
- Because it is a squareness master, it can be used as a parallelism master.
- The use surface has Precision lapping finishing
- Precision surface is the outer circumference square. The Accuracy surface is 10mm minused from the outer circumference.
- Because it is made of Granite, effects of changes in temperature is minimal.
