Cutting tool having an adjustment mechanism

A cutting tool comprising:

• a tool body comprising:
• an insert pocket having a base surface and a sidewall;
• a sidewall aperture located in the sidewall;
• an abutment member bore opening out to the sidewall at the sidewall aperture, the abutment member bore having an abutment member axis (M) defining an upward to downward direction;
• and
• an adjustment bore intersecting the abutment member bore, the adjustment bore having an adjustment bore axis (B) defining an inner to outer direction and an adjustment bore diameter DAB;
• an abutment member comprising:
• an abutment member peripheral surface extending between an abutment member upper surface and an abutment member lower surface;
• an abutment surface;
• and
• a worm screw bore formed in the abutment member peripheral surface, the worm screw bore having a worm screw bore axis (W);
• and
• a worm screw having a worm screw thread and a worm screw diameter DWS, with DAB>DWS;
• wherein:
• the abutment member occupies the abutment member bore;
• the worm screw occupies the adjustment bore with the worm screw thread engaging the worm screw bore formed in the abutment member;
• and
• the worm screw is rotatable between:
• a first screw rotated position in which the abutment member is located in a first position along the abutment member bore axis (M);
• and
• a second screw rotated position in which the abutment member is located in a second position along the abutment member bore axis (M).
