An inserted-blade cutter assembly uses a laterally projecting finger formed integrally with each removable blade which is engagable with a reference-positioning surface on the cutter body to precisely position the blade. Two locking caps have frustoconical surfaces which engage similarly shaped end portions of the blade members providing a sufficient radial force to counter centrifugal forces and thereby retain the blades in the body member. The locking caps also provide a sufficient axial force to keep the blade finger in contact with the reference-positioning surface to provide precise cutting tooth alignment during the cutting operation. This structure obviates the need for individual fasteners, shrink fits, or adhesives thereby facilitating blade removal and replacement. |
