ABSTRACT:
Disclosed is a shaper cutterhead utilizing an assembly that locates, captivates and firmly clamps two standard cutter bits that each include a hole designed to be engaged by solid lugs of a hub. Tee-slotted clamping collars that surround the hub slide laterally into place by engaging grooves in both bits and lock the bits rigidly when the machine spindle is tightened.
