Abstract
Embodiments of the invention provide a cutting tool. The cutting tool includes a pin that defines an axis, a first jaw, a second jaw, a first blade, and a second blade. The first and second jaws are configured to rotate about the axis. The first jaw includes a first ear surface that has a first ear bore that is dimensioned to receive the pin. The second jaw includes a second ear surface rotationally engaged with the first ear surface and includes a second ear bore that is dimensioned to receive the pin. The blades can include a tapered face and a non-tapered face. The first and second ear surfaces can be coplanar with the respective non-tapered face.

A cutting head for a power tool, the cutting head comprising:
- a jaw coupling assembly including a hollow pin, a press ring, and a nut, the hollow pin defining an axis and having a threaded end;
- a first jaw configured to rotate about the axis, the first jaw including a first ear having a first medial ear surface and a first ear bore, the first ear bore dimensioned to receive the hollow pin;
- a second jaw configured to rotate about the axis, the second jaw including a second ear having a second medial ear surface and a second ear bore, the second ear bore dimensioned to receive the hollow pin;
- a first blade;
- and
- a second blade,
- the nut torqued and threaded onto the threaded end of the hollow pin so that the press ring is seated between the nut and the first jaw.
A cutting tool comprising:
- a pin defining an axis;
- a first jaw configured to rotate about the axis, the first jaw including a first ear surface having a first ear bore that is dimensioned to receive the pin;
- a second jaw configured to rotate about the axis, the second jaw including a second ear surface rotationally engaged with the first ear surface and having a second ear bore that is dimensioned to receive the pin;
- a first blade coupled to the first jaw, the first blade having a first tapered face and a first non-tapered face opposite the first tapered face;
- and
- a second blade coupled to the second jaw, the second blade having a second tapered face and a second non-tapered face opposite the second tapered face,
- the first non-tapered face being coplanar with the first ear surface and the second non-tapered face being coplanar with the second ear surface.
A cutting tool head for a power tool, the cutting tool head comprising:
- a hollow pin defining an axis;
- a first jaw configured to rotate about the axis, the first jaw including a first clamp and a first ear having a first ear surface, the first ear surface having a first bore extending therethrough that is dimensioned to receive the hollow pin;
- a second jaw configured to rotate about the axis, the second jaw including a second clamp and a second ear having a second ear surface, the second ear surface rotationally engaged with the first ear surface and having a second bore extending therethrough that is dimensioned to receive the hollow pin;
- a first blade mounted on the first jaw via a first blade mount bolt;
- and
- a second blade mounted on the second jaw via a second blade mount bolt,
- the first clamp being dimensioned to distribute force applied from the first blade mount bolt across the first blade,
- the second clamp being dimensioned to distribute force applied form the second blade mount bolt across the second blade.
