Cutting tool with directed fluid flow to facilitate chip evacuation

A cutting ring comprising:

• one or more cutting head assemblies, each cutting head assembly including at least one support arm extending radially outwardly from a rotational axis, RA, of the cutting tool, and a cutting head supported by the at least one support arm;
• and
• one or more guide pad assemblies, each guide pad assembly including at least one support arm extending radially outward from the rotational axis, RA, and a guide pad head supported by the at least one support arm of each guide pad assembly,
• wherein the at least one support arm of each cutting head assembly comprises a fluid dynamic structure for directing fluid flow in a desired direction to facilitate chip evacuation during a cutting operation, and
• wherein the at least one support arm of each guide pad assembly comprises a fluid dynamic structure for directing fluid flow in a desired direction to facilitate chip evacuation during the cutting operation.

A cutting tool, comprising:

• a front cutting body;
• a rear machine connection member;
• a center tube having a front end and a rear end;
• a front cutting ring secured to the front end of the center tube and the front cutting body, the front cutting ring comprises one or more cutting head assemblies, each cutting head assembly including at least one support arm extending radially outwardly from a rotational axis, RA, of the cutting tool, and a cutting head supported by the support arm;
• and
• a rear cutting ring secured to the rear end of the center tube and the rear machine connection member, the rear cutting ring comprises one or more cutting head assemblies, each cutting head assembly including at least one support arm extending radially outwardly from a rotational axis, RA, of the cutting tool, and a cutting head supported by the support arm,
• wherein the at least one support arm of the front cutting ring comprises a fluid dynamic structure for directing fluid flow in a desired direction to facilitate chip evacuation during a cutting operation, and
• wherein the at least one support arm of the rear cutting ring comprises a fluid dynamic structure for directing fluid flow in a desired direction to facilitate chip evacuation during a cutting operation.
