Abstract

Specifies the dimensions of both forged collared shanks and corresponding chuck bushings. Values are given for five nominal sizes. This second edition cancels and replaces the first edition (1974), which has been technically revised (extension of the range of sizes and specification of the size of the internal diameter at the forged collar).
