ABSTRACT:
A collar is disclosed for mounting a radially separable cutting tool in installed concentrically on an arbor. The cutting tool is comprised of individual sectors that are radially separable, have inner edges that coact to define a center arbor receiving bore and apertures radially spaced from the inner edges for loosely receiving pins therein. The collar includes an annular flange having axially outer and inner faces and a bore for receiving the arbor therethrough. A plurality of pins are mounted in the collar flange and dimensional to loosely fit in the apertures in the cutter tool sectors. The pins project axially beyond the inner face and are movable radially toward and away from the bore for contact with the sectors mounted thereon to enable the pins to precisely move each sector into installed concentricity with the bore. A clamping mechanism is provided to clamp the cutter tool sectors against the inner face to maintain the sectors in installed concentricity.
