CUTTING TOOL HAVING COOLANT CHAMBER WITH INTEGRALLY FORMED COOLANT DEFLECTION PORTION AND TOOL BODY

A cutting tool (20) includes a replaceable cutting insert (22) and a tool body (24). The tool body (24) includes a tool body surface (26) and an insert pocket (28) recessed therein. The cutting insert(22) is releasably retained in the insert pocket (28). The tool body (26) includes at least one coolant duct (60a, 60b) that has an outlet orifice (56) that opens out in a coolant chamber (44). The coolant chamber (44) is bounded on a side opposite the outlet orifice (56) by a coolant deflection portion (58) that is integrally formed with the tool body (26) in a unitary one-piece construction andat least partially overhangs the outlet orifice (56) in a direction (P) towards the insert pocket (28). 切削刀具(20)包括可更换的切削刀片(22)和刀体(24)。刀体(24)包括刀体表面(26)和凹入其中的刀片槽(28)。切削刀片(22)可释放地保持在刀片槽(28)中。刀体(26)包括至少个冷却剂管道(60a，60b)，该冷却剂管道具有在冷却剂腔室(44)中敞开的出口孔(56)。冷却剂腔室(44)在与出口孔(56)相对的侧上通过冷却剂偏转部分(58)界定，冷却剂偏转部分(58)与刀体(26)体地形成为整体的单件式结构并且在朝向刀片槽(28)的方向(P)上至少部分地垂悬于出口孔(56)上。
