4 Configuration and dimensions
See hgure 1 and Table 1.
Dimensions and tolerances are expressed in millimetres. They are applicable after any coating (tolerance on shank diameter before coating is also specified for heat cured matrix coatings), but before the application of any lubricant.
Details of form not stated are left to the manufacturers discretion.
Tolerances of form and position shall be in accordance with ISO 7913.ISO 3185 pdf download.
