through-holesteelalloy

High standard gripping accuracy of 0.01mm or less with formed jaws gripping a test bar. Suitable for workpiece transfer with sub spindle. Low centrifugal force at high speeds. Interchangable with B210, BB210 & QJR10. Additional special Patented T-Nuts can be supplied to maintain 0.01mm or less repeatability even after changing jaws - significantly reducing set-up time. Chucks are manufactured from high grade alloy steel. Three jaw wedge style power chucks deliver up to 20% more speed, gripping force and bore size when compared to conventional chucks.
