Retention Knobs

One of the most critical components is the often-overlooked retention knob. The retention knob is the connection between the machine tool spindle and toolholder. Retention knobs, if incorrect or installed improperly can lead to spindle damage, reduced tool life, and poor surface finish. We offer two styles of high performance retention knobs, our standard knob and our high performance force control retention knob. Both designs are proudly made in the USA.
