R8 SHANK ER COLLET CHUCKS
R8 taper shank ER collet chucks are typically used on manual milling machines. The R8 taper end fits into a machine spindle and the ER collet nut is compatible with ER collet. The ER32 nut is compatible with the ER32 style collet and the ER40 nut works with the ER40 style collet. ER collets are used to hold all the machine tools with a round shank. These R8 shank ER collet chucks deliver a quality significantly above average on market. The total indicator runout (TIR) is less than 0.0002". The MAX RPM on the manual milling machines is 8,000. The manufacturer of the collet chucks inspects and produces them in a highly sophisticated lab and factory. You can hardly expect theÂ collet chucks from the other MFG to be of the same quality.
