The "m" (medium) class is the most common standard used in CNC machining. It provides a balanced approach between manufacturing cost and part functionality. Nominal Size Range (mm) Tolerance (± mm) Over 3 to 6 Over 6 to 30 Over 30 to 120 Over 120 to 400 Over 400 to 1000 Over 1000 to 2000 Over 2000 to 4000 Source: ZEISS Quality Forum ISO 2768-2: Geometrical Tolerances (Class H)

A brief comparative table (conceptual):

The "h" class defines the general tolerances for geometric characteristics. : Up to 10 mm: 0.1 mm 10 to 30 mm: 0.2 mm 30 to 100 mm: 0.4 mm 100 to 300 mm: 0.8 mm 300 to 1000 mm: 1.2 mm iso 2768-mh tolerance chart
