IS 9897 : 2024/ISO 1832 : 2017 Indexable Inserts for Cutting Tools - Designation
NATIONAL FOREWORD
This Indian Standard (Fourth Revision) which is identical to ISO 1832 : 2017 'Indexable Inserts for Cutting Tools - Designation' 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 1993 based on ISO 1832 : 1985 and was subsequently revised thrice to align with the latest versions of ISO 1832. This revision has been brought out to align it with ISO 1832 : 2017.
The main changes have been incoporated in this revision are as follows:
a) Normative references in 2 have been updated;
b) Table 5 has been modified by including new variety of rhombic inserts of shape V having 12.7 mm diameter of inscribed circle; and
c) Table 17 has been modified by including letter symbol for full cutting edge length.
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.
