• Tolerance calculation for workpieces:
   - plain shaft
   - plain hole
   - thread shaft
   - thread hole
 
• Tolerance calculation for gages:
   - plain plug
   - plain ring
   - thread plug
   - thread ring

• Effective diameter tolerance, drilling hole size, external and internal diameter of the gage.

• Various norms available:
