The PSI Super Center #2 MT 5/8" Crown Get a better bite on your spindle with PSI's new "Super Center". More teeth give a better bite while providing equal pressure and a positive drive. There is no need to hammer your drive center into the work piece and risk splitting your work. A spring loaded point simplifies the positioning of your spindle in the center and retracts to avoid spitting your work when tailstock pressure is applied. Compatible with headstocks with #2MT spindles. Crown is 5/8" wide for narrower work.
