Cutting assembly

A cutting assembly comprising:

• a toolholder and a cutting insert;
• the toolholder having an axial forward end and an axial rearward end, the toolholder having a head region at the axial forward end and a shank region at the axial rearward end;
• the head region containing a slot separating the head region into a lower section and an upper section wherein the upper section is movable relative to the lower section, and the lower section defining a lower seat and the upper section defining an upper seat wherein the lower seat and the upper seat being adapted to retain a cutting insert there between;
• the head region containing a fastener bore;
• the head region containing a coolant entrance passage in fluid communication with the fastener bore, and the head region containing a coolant delivery passage in fluid communication with the fastener bore, and the coolant delivery passage having an exit adapted to direct coolant to the cutting insert;
• and
• a fastener being received within at least a portion of the fastener bore, and the fastener having an axial fastener bore with an inlet and an outlet, the axial fastener bore inlet being in fluid communication with the coolant entrance passage and the axial fastener bore outlet being in fluid communication with the fastener bore.

A cutting assembly for removing material from a workpiece having a workpiece surface upon the cutting assembly engaging the workpiece at a cutting insert-workpiece interface, the assembly comprising:

• a toolholder and an elongate cutting insert, the elongate cutting insert having a central longitudinal cutting insert axis wherein the central longitudinal cutting insert axis being generally perpendicular to the workpiece surface;
• the toolholder having an axial forward end and an axial rearward end, the toolholder having a head region at the axial forward end and a shank region at the axial rearward end;
• the head region having a narrow axial forward extension having a central longitudinal extension axis, the head region containing a slot separating the narrow axial forward extension into a lower axial forward extension section and an upper axial forward extension section wherein the upper axial forward extension section is movable relative to the lower axial forward extension section, and the lower axial forward extension section defining a lower seat and the upper axial forward extension section defining an upper seat wherein the lower seat and the upper seat being adapted to retain the elongate cutting insert there between such that the central longitudinal cutting insert axis being generally parallel with the central longitudinal extension axis;
• the head region containing a fastener bore;
• the head region containing a coolant entrance passage in fluid communication with the fastener bore, and the upper axial forward extension section containing at least a portion of a coolant discharging section having a longitudinal coolant discharge axis;
• a fastener being received within the fastener bore, and the fastener having an axial fastener bore with an inlet and an outlet, the axial fastener bore inlet being in fluid communication with the coolant entrance passage and the axial fastener bore outlet being in fluid communication with the fastener bore;
• and
• the coolant discharging section being in fluid communication with the fastener bore, and the coolant discharging section having an exit in the upper axial forward extension section wherein the exit opens towards the cutting insert-workpiece interface so as to discharge coolant towards the cutting insert in a direction generally parallel to the central longitudinal cutting insert axis.
