IS 8692 : Part 2 : 2024/ISO 3338-2 : 2013 Cylindrical Shanks for Milling Cutters - Part 2 Dimensional Characteristics of Flatted Cylindrical Shanks
NATIONAL FOREWORD
This Indian Standard (Part 2) (Third Revision) which is identical to ISO 3338-2 : 2013 'Cylindrical shanks for milling cutters - Part 2: Dimensional characteristics of flatted cylindrical shanks' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Cutting Tools Sectional Committee and approval of the Production and General Engineering Division Council.
This standard was first published in 1978 and subsequently revised in 2004 and 2013. The original version of this standard was based on ISO 3338-1 : 1977 'Parallel shanks for milling cutters - Part 1: Dimensional characteristics of plain parallel shanks' and ISO 3338-2 : 1977 'Parallel shanks for milling cutters - Part 2: Dimensional characteristics of flatted parallel shanks'. First revision of this standard was identical to ISO 3338-2 : 2000 'Cylindrical shanks for milling cutters - Part 2: Dimensional characteristics of flatted cylindrical shanks'. Second revision of this standard was identical to ISO 3338-2 : 2007. This revision of this standard has been brought out to align it with the latest version of ISO 3338-2.
The major changes incorporated in this revision are as follows:
a) Annex A that provides relationship between symbols of ISO 3338-2 : 2013 and ISO 13399 (all parts) has been added; and
b) Bibliography has been added.
This standard has been published in three parts with general title 'Cylindrical shanks for milling cutters'. Other parts in this series are:
Part 1 Dimensional characteristics of plain cylindrical shanks
Part 3 Dimensional characteristics of threaded shanks
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
