Manual D688 Vise, 6" w/ 8.8" opening


The original Kurt Anglock D-Series vises are designed for precision part clamping on basic machine tools such as knee-type mills, grinders and machining centres. D-Series vises are ideal for use in running production parts where datums, flatness and parallelism is important. You can precision bore, tap, drill, grind and finish with high accuracy on most parts made of die cast aluminum, steel, and iron in your Kurt Anglock vises. No other brand can give you the time proven accuracy of the Kurt Anglock vises.

All Kurt vises have a friction reducing, needle bearing, thrust collar. The needle bearing increases jaw clamping pressure.
