Machining tool

A machining tool, comprising:

• a cartridge including a first end and an opposite second end, a front portion and a rear portion, and a top portion and a bottom portion, said front portion including a first recessed area at said first end, said first recessed area being defined by a first surface which is parallel to said rear portion and spaced from said front portion, and a partial cylindrical inner wall facing said first end, a first aperture comprising threads and extending from said top portion towards said bottom portion adjacent said partial cylindrical inner wall, said first aperture having a first diameter towards said top portion and a second diameter towards said bottom portion, said first diameter being greater than said second diameter and providing a cartridge opening between said first aperture and said first recessed area;
• an anvil for a cutting insert, said anvil including a forward portion and a rearward portion, a first side portion and a second side portion each extending between said forward portion and said rearward portion, and a partial cylindrical side wall extending from said first side portion to said second side portion, said forward portion including a second recessed area being defined by a second surface and at least one cutting insert retaining wall, said anvil further including a slotted portion extending into said anvil from said partial cylindrical side wall, said anvil being moveably affixed within said first recessed area such that said partial cylindrical side wall is in sliding contact with, and has a common axis with, said partial cylindrical inner wall, the diameter of said partial cylindrical inner wall being only slightly greater than the diameter of said partial cylindrical side wall to allow said partial cylindrical side wall to mate with and slide upon said partial cylindrical inner wall;
• and,
• an adjustment screw comprising a correspondingly threaded shank and an enlarged head, said correspondingly threaded shank being screwed into said first aperture and said enlarged head extending into said first aperture, said cartridge opening and said slotted portion for engaging said anvil to slide said partial cylindrical side wall relative to said partial cylindrical inner wall to rotate said anvil about said common axis.
