9、ernational Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee ha

10、s been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical

11、standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in acc

12、ordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Detai

13、ls of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an end

17、specifies the dimensions of the following three types of drills:a) parallel shank drills, stub series;b) parallel shank drills, jobber series;c) Morse taper shank drills.It comprises, for each type of drill mentioned above, three tables giving, respectively:a) the dimensions in millimetres;b) the di

18、mension in inches;c) the corresponding lengths, in millimetres and in inches, set out as functions of diameter steps.2 Normative referencesThere are no normative references in this document.3 Terms and definitionsNo terms and definitions are listed in this document.ISO and IEC maintain terminologica

19、l databases for use in standardization at the following addresses: IEC Electropedia: available at http:/www.electropedia.org/ ISO Online browsing platform: available at http:/www.iso.org/obp4 InterchangeabilityThe numerical tables have been drawn up in such a way as to ensure that the standard dimen

20、sions in millimetres and inches correspond as closely as possible.To this end, the complete range of diameters has been subdivided into a number of steps, the limits of which have been derived from the preferred number series for the metric values and converted directly from those for the inch value

21、s; the lengths and taper shank dimensions remain the same for the metric and the inch value within a given step.The recommended diameters in the two systems of units of measurement differ, however, and the number of recommended diameters in a given step also differs in one system from that in the ot

22、her.Finally, the tolerance on the diameter of the cutting portion has been standardized solely on the basis of the metric value of h8, converted directly into inches for inch drills.INTERNATIONAL STANDARD ISO 235:2016(E) ISO 2016 All rights reserved 1BS ISO 235:2016ISO 235:2016(E)5 Parallel shank tw
