Abstract
A cutting tool assembly includes a tool body and a tool holder. The tool holder includes a cylindrical portion connected to the tool body, an eccentric drive member, and a fastener hole configured to receive a securing fastener. The eccentric drive member can include a trigon portion comprising a rounded triangular cross section.
Claims6
An apparatus comprising a cutting tool assembly, comprising:
- a tool body;
- and
- a tool holder comprising a longitudinal axis around which the tool holder is configured to spin, the tool holder comprising:
- a cylindrical portion connected to the tool body comprising a cone-shaped fastener hole perpendicular with the longitudinal axis;
- and
- a trigon portion comprising a rounded triangular cross section connected to the cylindrical portion, the rounded triangular cross section comprising:
- three rounded vertices;
- and
- three arcuate faces between each of the rounded vertices;
- wherein the cone-shaped fastener hole is configured to receive a securing fastener and thereby rotationally orient and seat the trigon portion against a mating cavity and prevent the tool holder from becoming locked into the mating caving as a result of tool use.
