This British Standard specifies requirements for the mounting and accuracy of tool-holding chucks for use in machine tools and portable power tools and in particular to the five types of these chucks described in Clause 2. Examples of typical chuck capacities by types, and related mounting details are shown in Appendix A.
NOTE 1 The millimetre and inch dimensions given in Table 1, Table 2, Table 3 and Table 4 are sufficiently close conversions that chucks dimensioned in millimetres may be used with spindles dimensioned in inches and vice versa.
NOTE 2 In Clause 4, all the millimetre dimensions relate to chucks whose rated capacities are stated in millimetres and the inch dimensions to those whose rated capacity is stated in inches. Corresponding values are in general equivalent to each other but are not accurate conversions.
NOTE 3 More accurate conversions should be based on the data in BS 350, “Conversion factors and tables”.
