A cutting tool and cutter body assembly, including a disk-shaped cutter body and a plurality of support pads removably retained therein, the cutter body having an axis of rotation, two opposing end surfaces and a body peripheral surface extending therebetween. Each support pad intersects one of two annular-shaped planes equidistantly offset from opposite sides of a median plane perpendicular to the axis of rotation, and the cutter body intersects neither of the two annular-shaped planes. Each support pad is configured to make operative contact with a machined surface of a workpiece perpendicular to the axis of rotation. Each support pad has opposing upper and lower surfaces and a pad peripheral surface extending therebetween, the pad peripheral surface having an upper portion intersecting the upper surface, and the upper portion exhibiting N-fold rotational symmetry about a pad axis non-perpendicular to the lower surface. |

1. A cutter body assembly (20, 20′) comprising:
a disk-shaped cutter body (22) and a plurality of support pads (24, 24′) removably retained therein, the cutter body (22) having an axis of rotation (R), a direction of rotation (DR) about the axis of rotation (R), two opposing end surfaces (26a, 26b) and a body peripheral surface (28) extending therebetween, and each of the plurality of support pads (24, 24′) protruding from one of the two opposing end surfaces (26a, 26b), wherein a median plane (M) perpendicular to the axis of rotation (R) intersects the body peripheral surface (28), and two annular-shaped planes (P1) are equidistantly offset from opposite sides of the median plane (M) by a first distance (D1), and wherein each of the plurality of support pads (24, 24′) intersects one of the two annular-shaped planes (P1), and the cutter body (22) intersects neither of the two annular-shaped planes (P1). |
