3 Dimensions
3.1 General
All dimensions and tolerances are given in millimetres; tolerancing is according to ISO 8015. Tolerances not specified shall be of tolerance class “m”in accordance with ISO 2768-1 and of class “k” in accordance with ISO 2768-2.
3.2 Retention knobs, shank form AD, for centric inner cooling lubricant supply The dimensions of retention knobs for shanks of form AD shall be in accordance with the dimensions shown in Figure 1 and given in Table 1.
For shank forms AF and UF without a hole, it is possible to install a data medium hole; AF then becomes AC and UF becomes UC.
If a data medium hole is needed for form JF, the dimensions shall be defined by the manufacturer according to the data medium used. The location shall be as shown in Figure 7.See Figures 2 and 4 and Tables 2 and 4.The general dimensions are given in Table 6.ISO 7388-3 pdf download.
