Patent number: 8215719Abstract: 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.Type: GrantFiled: October 6, 2009Date of Patent: July 10, 2012Assignee: Kennametal Inc.Inventors: Adam Joseph Kelly, Chad Allen Swope
