A TURNING TOOL AND AN INDEXABLE TURNING INSERT5 AS WELL AS AN ATTACHMENT FOR SUCH TURNING TOOLS

摘要

In one aspect, the invention relates to an indexable turning insert (2), which has a symmetrical, preferably rotationally symmetrical basic shape that is determined by a clearance surface (22) extending between a top side (23) and an underside (24), and which includes a cutting edge (25) as well as a coupling means (21 ) located to the underside (24). Said coupling means comprises at least two, preferably three, suitably equiangularly spaced-apart engagement members (27) - preferably in the form of ridges - emanating radially from a centre axis (C) and having a pair of flanks that mutually form an obtuse angle. Furthermore, the invention relates to a turning tool and an attachment for the same.
