Abstract
A rotatable cutting tool for use in impinging earth strata such as, for example, asphaltic roadway material, coal deposits, mineral formations and the like. The rotatable cutting tool includes a cutting tool body having a through coolant channel and a two-piece head portion, e.g., the head portion of the cutting tool body having a base portion and a nose portion with a hard tip cutting insert affixed to the nose portion. The through coolant provides for cooling the hard tip cutting insert during operation of the cutting tool. In addition, the through coolant also provides for suppressing dust created by the rotatable cutting tool during operation.

A rotatable cutting tool for use in impinging earth strata, the rotatable cutting tool comprising:
- a cutting tool body;
- a hard tip affixed to the cutting tool body;
- the cutting tool body having an axial forward end for receiving the hard tip and an axial rearward end, a head portion axially rearward of the axial forward end, a collar portion axially rearward of the head portion, and a shank portion axially rearward of the collar portion and axially forward of the axial rearward end;
- the head portion including a base portion affixed to the collar portion and a nose portion movably connected to the base portion;
- and
- the cutting tool body defining an internal coolant channel extending axially from the axial rearward end through the shank portion, the collar portion and at least part of the base portion of the head portion, wherein the nose portion of the head portion is positioned adjacent to the internal coolant channel that extends through the base portion of the head portion.
