The insert has a cutting edge (3), two bevel (9a,9b) and a base surface opposite the cutting edge and formed for the firmly bonded attachment on a shaft end (5) of the percussion drilling tool (2). The base surface forms the former bevel circulating piecewise to an attachment surface arranged transverse to the base surface. The later bevel, that is broader than former bevel and circulating piece-wise, is designed at open surface (10) and arranged crosswise to bottom surface (6). |
