High-feed turning tool assembly

A two-directional high-feed turning tool assembly comprising:

• a tool holder, a cutting insert, and a clamping element;
• the tool holder comprising:
• opposite front and rear tool ends defining a longitudinal direction including a forward direction towards the front tool end and a rearward direction opposite thereto;
• opposite upper and lower tool sides defining a vertical direction including an upward direction towards the upper tool side and a downward direction opposite thereto;
• opposite first and second flank tool sides defining a sideways direction including a first side direction towards the first flank tool side and a second side direction opposite thereto;
• a vertical bisector plane extending parallel to the longitudinal and vertical directions, and bisecting the first and second flank tool sides adjacent to the front tool end;
• a shank portion;
• a head portion extending from the shank portion;
• and
• an insert pocket formed at an intersection of the front tool end and upper tool side of the head portion, the insert pocket comprising a pocket base surface;
• the cutting insert is secured to the insert pocket via the clamping element;
• the cutting insert comprising:
• opposite top and bottom surfaces, and an insert flank surface connecting the top and bottom surfaces;
• and
• a peripheral cutting edge formed along at least a portion of an intersection of the insert flank surface and the top surface, the peripheral cutting edge comprising at least one active cutting edge;
• the active cutting edge comprising:
• a forwardmost edge portion located forward of the front tool end, extending further in the forward direction than the remainder of the active cutting edge, and having a lateral edge length measurable parallel to the sideways direction;
• a first main edge portion extending from the forwardmost edge in both the first side and rearward directions to a location further in the first side direction than the first flank tool side adjacent the front tool end, the first main edge portion having a first edge length measurable parallel to the sideways direction and a first edge depth measurable parallel to the longitudinal direction;
• a second main edge portion extending from the forwardmost edge in both the second side and rearward directions to a location further in the second side direction than the second flank tool side adjacent the front tool end, the second main edge portion having a second edge length measurable parallel to the sideways direction and a second edge depth measurable parallel to the longitudinal direction;
• the first edge length being larger than each of the first edge depth and the lateral edge length;
• and
• the second edge length being larger than each of the second edge depth and the lateral edge length.
