ER-collet, sealed "Cool Tool" ER40 - Ø 25 repeatable accuracy 5µ

Application:
For clamping tools in ER-Collet Chucks and "Hawk Eye" ® Precision-ER-Collet Chucks.
Technical Design:
Highest runout accuracy combined with effective cooling and chip removal. Applicable up to 120 bar. Only shanks with nominal size 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.
