Abstract
A rotary cutting tool is provided that includes a shank and a body. The body extends axially outwardly from the shank, and has a plurality of first teeth and a plurality of second teeth. The first and second teeth are alternately arranged and spaced apart from one another around a circumference. Each first tooth includes a primary cutting edge disposed at a primary angle relative to the rotational axis and a tertiary cutting edge disposed at a tertiary angle relative to the rotational axis. Each second tooth includes a secondary cutting edge disposed at a secondary angle relative to the rotational axis. The secondary cutting edge is disposed axially between the primary cutting edge and the tertiary cutting edge.

A rotary cutting tool having a rotational axis, the tool comprising:
- a shank;
- and
- a body extending axially outwardly from the shank, the body having a plurality of first teeth, and a plurality of second teeth, the first teeth and second teeth are alternately arranged and spaced apart from one another around a circumference;
- wherein each first tooth includes a primary cutting edge disposed at a primary angle relative to the rotational axis and a tertiary cutting edge disposed at a tertiary angle relative to the rotational axis;
- and
- wherein each second tooth includes a secondary cutting edge disposed at a secondary angle relative to the rotational axis;
- and
- wherein the secondary cutting edge is disposed axially between the primary cutting edge and the tertiary cutting edge.

- wherein each first tooth includes a primary cutting edge disposed at a primary angle relative to the rotational axis and a tertiary cutting edge disposed at a tertiary angle relative to the rotational axis;
- and
- wherein each second tooth includes a secondary cutting edge disposed at a secondary angle relative to the rotational axis;
- and
- wherein the primary cutting edge, the secondary cutting edge, and the tertiary cutting edge are configured such that rotation of the tool and engagement of the tool into a workpiece causes:
- the primary cutting edge and the secondary cutting edge to form a primary surface and a secondary surface in a work piece, the primary surface and the secondary surface contiguous with one another;
- and
- the tertiary cutting edge to form a tertiary surface in the work piece, the secondary surface and the tertiary surface contiguous with one another;
- and
- the primary surface axially separated from the tertiary surface.
