Cutting Tool and Adaptor

Abstract

An adaptor (20, 76, 104, 106) secures a cutting head (16) to a tool holder (12, 14) having a passage for fluid. The adaptor (20, 76, 104, 106) has a corresponding passage (68, 94) for fluid to which a nozzle (22) is connected for the distribution of fluid towards a cutting region (54) of the cutting head (16).

Claims

1. An adaptor for a cutting tool comprising: a rod defining a fluid path;a cap attached to an end of the rod;the rod and the cap defining a fluid path;at least part of the cap being configured to support a nozzle to deliver fluid from the fluid path to a cutting area;wherein the cap has a radial dimension of sufficient dimension to engage a cutting head and the rod has a length of sufficient dimension to engage a tool holder, a combination thereof linking the cutting-head to the tool holder in an axial direction.

2. The adaptor of claim 1 wherein the rod comprises a peripherally threaded rod wherein the peripherally threaded rod is configured to engage a tool holder.

3. The adaptor of claim 1 wherein the cap comprises a flange and a head through which the fluid path extends wherein the flange is configured to secure at least a portion of a cutting tool to a cutting tool holder such that the fluid path of the rod is in fluid communication with a fluid source associated with the cutting tool holder.

4. The adaptor of claim 3 wherein the fluid source is at least one holder channel defined by the cutting tool holder.

5. The adaptor of claim 4 wherein the holder channel is generally co-axial with the fluid path.

6. The adaptor of claim 3 wherein the head comprises at least one of a group comprising a hexagonal head, a general X shape, and a general cylindrical shape having a plurality of key ways.

7. The adaptor of claim 1 wherein the rod defines an internal adaptor threading defined by at least a portion of the fluid path proximal to the cap wherein the internal adaptor threading is configured to engage a nozzle for directing fluid from the fluid path to at least a portion of the cutting tool.

8. The adaptor of claim 1 further comprising at least one side adaptor channel defined by the rod wherein the at least one side adaptor channel is in fluid communication with the fluid path and a fluid source associated with the cutting tool holder when the adaptor secures a cutting tool to the cutting tool holder.

9. The adaptor of claim 1 further comprising a lock-nut for securing a nozzle to the cap.
