Notes:
If a feature is critical for a "press-fit" (like a bearing housing) or requires extreme precision for airtight seals, . In those specific cases, you must manually define a tighter tolerance (e.g., +/- 0.01mm) directly on that dimension. iso 2768-mh tolerance chart

is a combination designation used in engineering drawings to specify general tolerances for parts without individual tolerance indications. It combines two distinct parts of the ISO 2768 standard: "m" (medium precision) for linear and angular dimensions, and "H" (high precision) for geometrical features. Understanding the "mH" Designation . In those specific cases
: Unless specified, external broken edges (chamfers/radii) follow linear tolerance class m: ±0.1 to ±2.0 depending on size.
