Different techniques are normally used for assembling insert-holders of metal cutting tools. For instance, mechanical clamping, brazing and adhesive bonding are common techniques for assembling metal cutting tools insert-holders. The present work addresses the impact of the assembly technique on the dimensional accuracy and geometrical tolerances of machined workpieces. Extensive cutting tests conducted on mild steel specimens using different insert holder assembly techniques, revealed that bonded assembly ranked ahead in preserving dimensional accuracy and geometrical tolerances, when compared with mechanical clamped and brazed assemblies.
