Check the listing for details. ISO30 ER16 70mm Precision Chuck G2.5 30000RPM. Condition: New, Made in United States. Listed at 17.80 USD. Fitment: ISO30 ER16 Collet Chuck 70mm G2.5 30000 RPM CNC Tool Holder Description： 70mm (2.75 inch) length .00016" or 4 micron precision Balanced at G2.5 30,000 RPM standards (might be marked GM2.5) ER16 collet size Balancing helps with vibration which prevents premature bearing failures in the spindle. Balancing was performed on a machine to meet the G2.5 specification for 30K rpm. Precision decreases runout which causes chip thickness to vary over the tool rotation and therefore the tool experiences uneven forces during each cutting flute period. This will force a reduction in feedrate and tool life because one flute is doing more work. .
