For a 100mm shaft (Class "m"), the tolerance is ±0.3mm. If you need tighter than this, you must specify the dimension individually (e.g., 100 +0.02/-0.00 ). Table 2: Angular Dimensions Angles (e.g., a 45° chamfer) have their own rules. The tolerance depends on the length of the shorter side of the angle.
