Slitting tool configured for fine-tuning

A slitting tool comprising:

• a slitting tool basic body comprising:
• opposing first and second side surfaces connected by a peripheral edge;
• a disc-shaped body portion having an axis of rotation (AR) and a direction of rotation;
• at least one cutting portion extending from the body portion and connected thereto by a neck section thereof, the at least one cutting portion having a head portion provided with a relief portion and a rake portion;
• a groove separating the body portion from the cutting portion and having a peripheral opening that is rotationally forward of the neck section in a side view of the body portion along the axis of rotation (AR), the groove having a first groove surface formed on the body portion and a second groove surface formed on the cutting portion, the groove further having a front end portion remote from the neck section, a rear end portion proximate to the neck section and a central portion extending therebetween;
• a threaded biasing bore formed in the cutting portion and opening out to the second groove surface, the threaded biasing bore is the only threaded bore opening out to the groove, the biasing bore having a biasing axis extending through a center thereof;
• and
• a biasing surface formed on the first groove surface and located within a plan view of the biasing bore, the biasing surface being obliquely oriented relative to the biasing axis at an intersection thereof;
• and
• a biasing screw located in the biasing bore, the biasing screw having a first end configured to mate with a fastening tool, a second end configured to press against the biasing surface and a screw body portion extending between the first and second ends;
• wherein:
• the biasing bore is formed rotationally forward of the relief portion, in said side view;
• the slitting tool is adjustable between:
• an initial position in which the biasing screw and biasing surface are not in contact with one another, and
• a final position in which the second end of the biasing screw presses against the biasing surface and the cutting portion is repositioned, relative to the body portion, to a fine-tuned position;
• the biasing screw is the only element located in the groove and contacting both the first groove surface and the second groove surface, when the slitting tool is in the final position;
• and
• the at least one cutting portion comprises one or more cutting edges which collectively protrude beyond both the first and second surfaces in an axial direction along the axis of rotation (AR), and establish a width of cut of the slitting tool.
