Abstract

Methods and apparatus for making and using tools, for example concrete cutting blades. The tool includes a first layer and a second layer that are oppositely disposed. The first and second layers include working surfaces that support at least one working element when the working element is applied to a work piece. Additionally, an intermediate structure is included between the first and second layers. The intermediate structure can include a plurality of components extending in the area between the structural surfaces and the working surfaces.

First claim

What is claimed is:

1. A cutting tool comprising:
a first disk having an inner and outer face;
a second disk having an inner and outer face, wherein the inner face of the first disk and the inner face of the second disk face each other;
a structure interposed between the first disk and the second disk;
a ring coupled with the first disk and the second disk; and
a plurality of cutting segments coupled with the ring,
wherein the structure comprises a honeycomb structure.

2. The cutting tool of claim 1 , wherein the ring includes non-uniformities.

3. The cutting tool of claim 2 , wherein the non-uniformities are scallop portions.

4. The cutting tool of claim 1 , wherein the structure further comprises at least one of an adhesive or foam.

5. The cutting tool of claim 1 , wherein the first disk is made of one of metal, fiberglass, or plastic.

6. The cutting tool of claim 1 , wherein the structure is an adhesive.

7. The cutting tool of claim 1 , wherein the structure is one of a flow insert or a damping insert.

8. The cutting tool of claim 1 , wherein the ring is at least located partially between the first disk and the second disk.

9. The cutting tool of claim 1 , wherein the ring and the structure have substantially the same height.

10. A cutting tool comprising:
a first disk having an inner and outer face;
a second disk having an inner and outer face, wherein the inner face of the first disk and the inner face of the second disk face each other;
a ring coupled with the first disk and the second disk, the ring being partially located between the first disk and the second disk; and
a plurality of cutting segments coupled with the ring;
wherein the ring includes non-uniformities comprising scalloped portions.

11. The cutting tool of claim 10 , further comprising a structure interposed between the first disk and the second disk.

12. The cutting tool of claim 11 , wherein the structure comprises a honeycomb structure.

13. The cutting tool of claim 12 , wherein the structure further comprises at least one of an adhesive or foam.

14. The cutting tool of claim 11 , wherein the structure is an adhesive.

15. The cutting tool of claim 11 , wherein the structure is one of a flow insert or a damping insert.

16. The cutting tool of claim 11 , wherein the ring and the structure have substantially the same height.

17. The cutting tool of claim 10 , wherein the first disk is made of one of metal, fiberglass, or plastic.

18. The cutting tool of claim 10 , wherein the plurality of cutting segments are substantially arc shaped.
