Claims32
A tool holder comprising:
- a tool shank having a shank axis defining forward and rearward directions;
- and
- a tool head connected to the tool shank, the tool head having a tool head length LH and comprising a pocket configured to accommodate a parting blade or a cutting insert;
- the tool shank comprising:
- opposing uppermost and lowermost shank surfaces which define upward and downward directions perpendicular to the shank axis;
- and
- first and second shank side surfaces which define first and second side directions perpendicular to the shank axis and the upward and downward directions;
- wherein:
- adjacent to at least a portion of the first shank side surface, there is a reinforcement portion connecting the first shank side surface and the tool head, the
- reinforcement portion and the shank portion overlapping along the shank axis,
- the entire reinforcement portion is located rearward of the tool head;
- the reinforcement portion extends further in the downward direction than the lowermost shank surface,
- the reinforcement portion has a reinforcement portion width HW measurable perpendicular to the upward and downward directions and the shank axis, and
- along the tool shank, the tool holder has an overall width HT measurable perpendicular to the upward and downward directions and the shank axis, the overall width HT comprising a shank portion width HD and the aforementioned reinforcement portion width HW, the reinforcement portion width HW being smaller than the shank portion width HD.
