Specifies cutters generally aligning with those given in BS 122: Part 3: 1974 and the equivalent ISO Standards, although there are marginal differences on bore tolerance, range of bores, and external dimensions. Some typical features are listed, including number of teeth and cutting edge angles. The latter are defined fully to encourage uniform description of the cutting edge geometry.

This standard specifies basic features, dimensions, and tolerances for cylindrical, side-and-face, slotting, shell end mill, and metal-slitting saw milling cutters.Keyway details are provided, and details of arbor keys and spigots, as well as of retaining bolts and tenons for shell end mill arbors are given in Appendices A and B.
