Amazing Accuracy for Demanding Users You no longer have to deal with the, “just OK”, accuracy of the Sherline chucks...or the super tiny Sherline WW collet system that don’t allow for thick or longer stock to be held.  Remember, the more surface area that you are clamping...the more surface area you can cut.  Of the ER systems we offer, using our ER32 and ER40 headstocks will allow you the maximum clamping surface area and the largest stock holding capabilities. What You Get In Our ER Spindle Pre-Loaded Headstocks - - Precision ER spindle TIR .0005” or better - Collet nut and wrench - Precision ball bearings good to 8,000RPM (24,00rpm with hybrid anuglar contact bearing upgrades and balancing)
