Manual Expanding Mandrel

Manual Expanding Mandrel is designed to provide reliable precision machining and production for professional machining and production applications.

KEM Series of Manual Expanding Mandrels includes a manually-operated expanding mandrel actuator incorporating. A precision-ground 38mm diameter spigot for mounting in collet or jaw chucks. These models utilise the same precision mandrels. Expanding sleeves and locators as our CNC Expanding Mandrels. They are side-actuated with an included square-drive key. So that The system can accommodate parts with blind bores as well as those with thru-holes. Precision-ground for high accuracy in squareness and concentricity, If higher accuracy is needed the mandrel can be clocked-in once the unit is gripped in a chuck.
