    摘要： The present invention relates to turning insert, a turning tool body and turning tool for cutting metal workpieces, preferably by grooving or parting. The turning insert comprises at least one cutting head and a support body (7) extending rearward from the cutting head (5) .The support body (7) comprises a top surface (14) and a bottom surface (15), which each extend longitudinally rearward form the cutting head, which both comprise one insert interface (18) each for. Each insert interface (18) comprises a set of flanks (19, 22) forming alternating parallel, straight and rearward extending ridges (20) and grooves (21), wherein the ridges (20) and grooves (21) extend in a length direction. Each flank (19, 22) of each set of flanks extends from an outer peak (26) of an associated ridge (20) to an inner bottom (24) of an associated groove (21), Each set of flanks (19, 22) comprises a central main pair of flanks (22), which consists of the first flank on a respective lateral side of the longitudinal axis (8). At least along a major portion of the extension in the length direction of the flanks (19, 22), as seen in the cross section perpendicular to the length direction, the depth (31) of the central main pair of flanks (22) is larger than the depth (31) of all other flanks (19) of the same insert interface (18).

    摘要： This grooving tool includes a cutting insert (2), a holder (3), and a coolant flow path (4). The holder (3) includes an insert mounting seat (35), and jaw parts (36) that are disposed on an upper side and a lower side of the insert mounting seat (35) and fix the cutting insert (2). The jaw part (36) forms a curved shape as viewed from a tool distal end side, and has a thickness that is decreased as a distance from the insert mounting seat (35) is increased. The coolant flow path (4) includes a jaw part flow path (43) extending through an inside of the jaw part (36), and the jaw part flow path (43) includes a guide flow path section (44) that has a vertically elongated shape with a dimension a in the vertical direction larger than a dimension b in the tool width direction in a channel cross section, and an ejection flow path section (45) that has a laterally elongated shape with the dimension b in the tool width direction larger than the dimension a in the vertical direction in the channel cross section.
