Techniks Inc. ( has introduced a toolholding fixture that mounts to the side of a tool cart or bench and secures toolholders for changing cutting tools, collets, and pull studs. The NT S Tightening Fixture is designed to work with: CAT , BT, ISO, and HSK toolholders. Toolholders are placed in the NTS fixture and the locking screw knob is tightened to engage the drive slot or wrench flats – depending on the toolholder – to secure the toolholder. Techniks recommends using a torque wrench and tightening to specifications to insure safety and improve cutting tool life.
