ER-collet, sealed ER20 - Ø 12 repeatable accuracy 5µ

Application:
For clamping tools in ER-Collet Chucks and "Hawk Eye" ® Precision-ER-Collet Chucks.
Technical Design:
For tools with internal coolant up to 120 bar! Only shanks with standard dimensions can be used, tolerance h8. Shanks with lateral clamping flat can only be used limited, which means the clamping flat has to be behind the sealing plug, otherwise the coolant can leak along the shank.
