Flexible cartridge with precision adjustment

A tool for rotating a differential screw of a tool cartridge for a material removal tool, the tool cartridge including a cartridge body, an axial adjustment screw at a first end of the cartridge body, an opening for a clamping screw proximate the first end of the cartridge body, a seat for a cutting tool insert at a second end of the cartridge body, a recess extending through at least a portion of the cartridge body from a first side toward a second side, a long axis of the recess non-parallel to a long axis of the cartridge body and at least a portion of the recess open to a bottom surface of the cartridge body, and a threaded opening for the differential screw proximate the second end and positioned, relative to a long axis of the tool cartridge, longitudinally between the opening for the clamping screw and at least a portion of the seat, wherein a thread axis of the threaded opening for the differential screw is at a non-perpendicular angle G relative to the long axis of the tool cartridge and intersects the bottom surface of the cartridge body at a non-perpendicular angle, wherein the threaded opening for the differential screw extends from a first opening in a top surface of the cartridge body to a second opening in a bottom surface of the cartridge body, wherein, relative to the long axis of the cartridge body, the first opening is axially closer to the opening for the clamping screw than the second opening and the second opening is axially closer to the second end of the cartridge body than the first opening, and wherein the long axis of the recess is positioned, relative to the long axis of the cartridge body, longitudinally between the threaded opening for the differential screw and the opening for the clamping screw, the tool including:

• a tool body;
• means for engaging the differential screw for rotating the differential screw about a screw axis;
• and
• a light projection device.
