Rotary cutting tool having disk-shaped cutter body provided with support pads

A support pad (24, 24′) removably retainable in a disk-shaped cutter body (22), comprising:

• opposing upper and lower surfaces (44, 46) and a pad peripheral surface (48) extending therebetween,
• the lower surface (46) being planar and configured to abut an associated seat surface (42) of a pad pocket (40) in the cutter body (22), and
• the pad peripheral surface (48) having an upper portion (50) intersecting the upper surface (44),
• wherein the upper portion (50) exhibits N-fold rotational symmetry about a pad axis (A2), and
• wherein the pad axis (A2) is non-perpendicular to the lower surface (46).

A cutter body assembly comprising:

• a disk-shaped cutter body having an axis of rotation and a direction of rotation (DR) about the axis of rotation (R);
• the cutter body comprising a central hub connected to an outer annular body portion, two opposing end surfaces, a body peripheral surface extending between the two opposing end surfaces, and a plurality of insert receiving pockets circumferentially spaced about the body peripheral surface;
• and
• a plurality of support pads located radially inward of the body peripheral surface, each support pad protruding axially outwardly of an entirety of only one of the two opposing end surfaces.
