Abstract

A cutter and a kit. The cutter, such as a close quarters cutter, is operable to cut a work piece extending along an axis and includes a cutting wheel, a roller, and a housing assembly supporting the cutting wheel and the roller for movement about the axis in a cutting direction to cut the work piece. The housing assembly has a generally cylindrical outer surface engageable by a user to pivot the cutter about the axis. A grip portion is provided on the outer surface and includes a plurality of grip members. Each grip member includes, relative to the cutting direction, a trailing surface and a leading surface extending from the outer surface. The leading surface may be angled toward the cutting direction.

First claim

We claim:

1. A cutter operable to cut a work piece extending along an axis, the cutter comprising:
a cutting wheel selectively engageable with and operable to cut the work piece; and
a housing assembly supporting the cutting wheel for movement about the axis in a cutting direction to cut the work piece, the housing assembly having a generally cylindrical outer surface engageable by a user to pivot the cutter about the axis, a grip portion being on the outer surface and including a plurality of grip members, each grip member including, relative to the cutting direction, a trailing surface and a leading surface extending from the outer surface, the housing assembly further comprising a generally cylindrical outer wall and side walls defining an opening receiving the work piece, and the trailing surface of one or more grip members is closer to radial alignment with a central axis of the housing assembly than the leading surface, wherein the leading surface extends from the trailing surface at least partially radially inward towards the central axis;
wherein the outer wall and the side walls cooperating to define a cavity in which the cutting wheel is at least partially supported, at least one of the side walls defining a plurality of circumferentially-spaced openings communicating between the cavity and an exterior of the cutter.

2. The cutter of claim 1 , wherein the trailing surface of each grip member extends substantially radially.

3. The cutter of claim 1 , wherein the leading surface and the trailing surface intersect at an edge from which they both extend, and the leading surface and the trailing surface define an angle between approximately 45 degrees and approximately 75 degrees.

4. The cutter of claim 1 , at least one side wall including a cutting direction indicator.

5. The cutter of claim 4 , wherein the cutting direction indicator includes an arrow pointing in the cutting direction.

6. The cutter of claim 1 , further comprising a roller supported by the housing assembly and engageable with the work piece, the roller having a generally cylindrical roller surface and an annular groove having a concave surface extending into the roller surface.

7. A cutter operable to cut a work piece extending along an axis, the cutter comprising:
a cutting wheel selectively engageable with and operable to cut the work piece; and a housing assembly supporting the cutting wheel for movement about the axis, the housing assembly including a generally cylindrical outer wall and side walls defining an opening receiving the work piece, the outer wall and the side walls cooperating to define a cavity in which the cutting wheel is at least partially supported, the housing assembly defining a plurality of circumferentially-spaced openings communicating between the cavity and an exterior of the cutter, the circumferentially-spaced openings being angled relative to the cutting direction; wherein the cylindrical outer wall has an outer surface engageable by a user to pivot the cutter about the axis, a grip portion being on the outer surface and including a plurality of grip members, each grip member including, relative to the cutting direction, a trailing surface and a leading surface extending from the outer surface, the leading surface being angled toward a cutting direction.

8. The cutter of claim 7 , wherein the plurality of circumferentially-spaced openings are defined by at least one of the side walls.

9. The cutter of claim 8 , wherein the plurality of circumferentially-spaced openings are defined by each side wall.

10. The cutter of claim 8 , wherein the at least one side wall has an axially-raised surface.

11. The cutter of claim 10 , wherein the at least one side wall has an axially-recessed surface defining the openings such that the circumferentially-spaced openings are axially recessed from the axially-raised surface.

12. The cutter of claim 7 , wherein the outer wall has an inner surface at least partially defining the cavity, and wherein the circumferentially-spaced openings are positioned radially proximate the inner surface.

13. The cutter of claim 7 , wherein the circumferentially-spaced openings are defined by the outer wall.

14. The cutter of claim 7 , further comprising a roller supported by the housing assembly and engageable with the work piece, the roller having a generally cylindrical roller surface and an annular groove having a concave surface extending into the roller surface.
