IMPORTANT: Inserting the cutting tool less than 2/3 the gripping length into the collet can damage the collet permanently.
Full length of the gripping bore must be maintained to achieve maximum accuracy and safety.
Collet accuracies are based on size-for-size conditions. Using the collapsible range can influence the accuracy and gripping powers.
Never try to stretch the collets by clamping oversized cutting tools.
