Abstract

A rotating tool includes a plurality of elongated members, and a support for holding the elongated members relative to an axis of rotation of the tool, wherein a guiding pad extends from at least one of the elongated members.

Claims

1. A rotating tool, comprising:

a plurality of elongated members; and

a support for holding the elongated members relative to an axis of rotation of the tool, wherein a guiding pad extends from at least one of the elongated members.

2. The rotating tool as set forth in claim 1, wherein the support comprises a first disk to which first ends of the plurality of elongated members are attached and a second disk to which second ends of the plurality of elongated members are attached.

3. The rotating tool as set forth in claim 2, wherein the support comprises at least one intermediate disk between the first and second disks, the at least one intermediate disk comprising openings through which the plurality of elongated members extend.

4. The rotating tool as set forth in claim 1, wherein the support comprises a disk having a plurality of radial openings, each of the radial openings being open to a radial edge of the disk, and wherein a pad extends outwardly from each radial opening beyond a circumferential surface of the disk.

5. The rotating tool as set forth in claim 1, wherein a cutting edge extends from at least one of the elongated members.

6. The rotating tool as set forth in claim 5, wherein the cutting edge is formed on a removable cutting insert that is mounted to the at least one of the elongated members.

7. The rotating tool as set forth in claim 6, wherein the position of the cutting edge relative to the at least one of the elongated members is adjustable.

8. The rotating tool as set forth in claim 5, wherein the cutting edge extends axially from a forward end of at least one of the elongated members.

9. The rotating tool as set forth in claim 8, wherein the support comprises a disk having a plurality of openings extending from a first side of the disk to a second side of the disk, each elongated member extending through a corresponding one of the openings.

10. The rotating tool as set forth in claim 9, comprising a recess in the disk in front of the cutting edge in a direction of rotation of the rotating tool.

11. The rotating tool as set forth in claim 5, wherein the cutting edge extends radially from a side of at least one of the elongated members.

12. The rotating tool as set forth in claim 1, wherein a guiding pad extends from at least one of the elongated members.

13. The rotating tool as set forth in claim 1, wherein at least one of the elongated members comprises an internal passage.

14. The rotating tool as set forth in claim 13, wherein a channel extends from the internal passage to an exterior of the at least one of the elongated members proximate a cutting edge on the at least one of the elongated members.

15. The rotating tool as set forth in claim 13, wherein a channel extends from the internal passage to an exterior of the at least one of the elongated members proximate a guiding pad on the at least one of the elongated members.
