Abstract:
1. A material removal tool, comprising: a housing body including a connector at a mating end; a piston head in an actuating chamber internal to the housing body; a translating bar including two or more actuation surfaces; a plurality of support pads at a distal end from the connector, the plurality of support pads oriented axially at various radial positions around the circumference of the distal end; a first delimiting structure and a second delimiting structure, wherein the second delimiting structure is an adjustable positive stop that limits axial movement of the translating bar in a first direction, wherein the material removal tool is configured to vary a limit of the axial movement of the translating bar in the first direction by adjustment of the adjustable positive stop; and two or more cutting positions arranged axially along a length of the material removal tool between the connector and the plurality of support pads, wherein the two or more cutting positions define an active portion of the material removal tool, wherein each cutting position includes a first flexibly mounted cartridge, the first flexibly mounted cartridge including at least one seating pocket for a cutting insert, wherein the translating bar includes a first end operably connected to the piston head to axially translate between a first position and a second position when the piston head translates, wherein in the first position, the active portion has an active volume determined by a greatest radial extent of the housing body in the active portion and a radially outermost surface of a cutting insert seated in the seating pocket on the first flexibly mounted cartridge is radially inward from a surface of the active volume, wherein in the second position, the radially outermost surface of the cutting insert seated in the pocket on the first flexibly mounted cartridge is radially outward from the surface of the active volume, and wherein the two or more actuation surfaces include a cone or frustum, wherein an axial position of a first actuation surface along a length of the translating bar corresponds to a position of a push rod in operable contact with the first flexibly mounted cartridge from a first cutting position and an axial position of a second actuation surface along a length of the translating bar corresponds to a position of a push rod in operable contact with the first flexibly mounted cartridge from a second cutting position.
