Technical Information Hydraulic Chucks WIDIA Slim Line Design Weldon shanks with a maximum diameter of 20mm (3/4") can be gripped without reducer collets. However, WIDIA recommends using reducer collets for all flatted shanks. Highest accuracy is obtained with plain, cylindrical shanks. Using a sleeve gives higher grip torque: Formula: sleeve bore x chuck torque = assembled torque chuck bore Example: 12mm (sleeve bore) x 220 Nm = 132 Nm 20mm (chuck bore) While chart shows for a 12mm Hydraulic Chuck = 70 Nm approx. 2x grip advantage K62 WIDIA"
