This International Standard specifies a series of relief grooves for shafts and holes, intended for general
use in mechanical engineering.
It also intends to avoid unnecessary multiplicity of tools by a restricted selection of groove-types and
dimensional versions.
NOTE The shape and the dimensions of the relief grooves type G and H correspond with the "Indexable hard
material inserts" according to ISO 6987.Cross References:ISO 128-22ISO 128-24ISO 6987Incorporates the following:Corrigendum, October 2019
