A cutting tool holder blade (100,101) is formed of hard metal such as cemented carbide, the cutting tool holder blade (100,101) having a front plane (F), a perpendicular mid-plane (P). An insert pocket (104) of the holder blade (100,101) has a base jaw (106) and a clamping jaw (110) resiliently connected to the base jaw (106) in a unitary one piece construction. The base jaw (106) has a base jaw abutment surface (108) and the clamping jaw (110) has a clamping surface (112) facing opposite the base jaw abutment surface (108), and an insert stop surface (114). A curved inner surface (116) extends from the base jaw abutment surface(108) towards and along the clamping jaw (110), the curved inner surface (116) having a front extremity portion (118). The clamping jaw (110) is narrowed down adjacent the front extremity portion (118), such that the clamping surface (112) overhangs the front extremity portion (118) of the curved inner surface (116), in a direction towards the base jaw (106) and away from the front plane (F). |
