External and internal turning tool with coolant

A turning tool comprising:

• a tool body having an insert seat with a bottom support surface;
• a cutting insert fastened to the insert seat, the cutting insert having a top surface and a bottom surface below, and opposite, the top surface, wherein a side surface connects the top surface and the bottom surface, and wherein a cutting edge is formed at an intersection between the side surface and the top surface, wherein the side surface forms a clearance surface associated with the cutting edge, the top surface forms a chip surface associated with the cutting edge, and the bottom surface is in engagement with the bottom support surface;
• a guiding block pivotally mounted on the tool body, the guiding block pivotally mounted about a pivot axis between a first position and a second position, wherein the pivot axis is located below the bottom surface of the insert seat;
• and
• a fluid passage with an inlet end and an outlet end, the outlet end includes a first outlet in the guiding block and a second outlet in the guiding block, the fluid passage is arranged to guide a cooling fluid from the inlet end to the outlet end,
• wherein a first section of the fluid passage extends through the tool body, wherein a second section of the fluid passage extends through the guiding block, and wherein a third section of the fluid passage extends through the guiding block,
• wherein each of the first and second outlets is arranged to eject a jet of the cooling fluid towards an area where the clearance surface is located in order to wet the clearance surface,
• wherein the guiding block is pivotal between a first position and a second position,
• in the first position, a first jet of cooling fluid is configured to be ejected along a first path from the first outlet, and the second outlet is inactive, and
• in the second position, a second jet of cooling fluid is configured to be ejected along a second path from the second outlet, and the first outlet is inactive, wherein the first path and the second path have different starting points and intersect each other in a respective downstream direction of each outlet, the starting point of each of the first path and the second path being below the insert seat, below being in a downward direction of the tool body extending into the tool body through the bottom surface and away from the top surface.
