ERgo is the new trademark of the Nine9 ER type indexable tool, which adopts a one-piece design. ERgo enhances tool rigidity and eliminates reassembly tolerances; better rigidity leads to good surface finishing and surface roughness, as well as longer tool life. ERgo utilized the characteristics of the enlarged diameter of the large end of the ER to make the rigidity of alloy steel surpass the rigidity of the all-tungsten steel indexable tool, so that the tool extension length ratio can be increased. ERgo is especially suitable for small equipment, such as BT30, tapping and turning centers; is the ideal solution for machine spindles with ER.
