US 2026/0233315 A1 · CUTTING TOOL AND RELATED METHODS

Abstract

A cutting tool includes a body have a first end and a second end opposite the first end. The second end can have one or more cutting elements positioned thereon adjacent to one or more fluid ejection ports positioned to facilitate injection of fluid out of the body and adjacent to the cutting elements. The first end can have a chamber defined therein that is in fluid communication with the one or more apertures via one or more conduits defined to extend from the chamber to the one or more ejection ports. In some embodiments, flutes can be defined adjacent a second end of the body and cutting elements can be positioned on or adjacent the flutes. At least some of the ejection ports can be positioned to emit coolant to cool the flutes and direct debris along the flutes away from the cutting elements.

Dependent claims

A cutting tool comprising:

a body having a first end and a second end opposite the first end, the first end of the body defining a coolant fluid feed chamber that is in fluid communication with at least one outer conduit defined in the body, each of the at least one outer conduit including a coolant ejection port feed conduit segment positioned to fluidly connect a coolant ejection port defined adjacent to the second end of the body to the coolant fluid feed chamber;
the body having at least one flute, each of the at least one flute being positioned adjacent to at least one cutting element attachable to the second end of the body.

A process of making and/or using a cutting tool, comprising:

forming a body of a cutting tool via an additive manufacturing process, the body having:
a first end and a second end opposite the first end, the first end of the body defining a coolant fluid feed chamber that is in fluid communication with an inner conduit, a first outer conduit, and a second outer conduit defined in the body, the first outer conduit including a coolant ejection port feed conduit segment positioned to fluidly connect a first coolant ejection port defined adjacent to the second end of the body to the coolant fluid feed chamber, the second outer conduit including a coolant ejection port feed conduit segment positioned to fluidly connect a second coolant ejection port defined adjacent to the second end of the body to the coolant fluid feed chamber;
the body having a first flute positioned adjacent to the first coolant ejection port and a second flute positioned adjacent to the second coolant ejection port.
