Available with the CB3-BD-TP and the CB3-BD-TP-TA CRI-BORE unit are two Intermediate Adapters, one measuring 3 inches in length and the other is 6 inches. By using them singly, or in combination, a wide range of depths of bore may be obtained. This practical system establishes bar length as required rather than being committed to a boring bar of exceptional length to bore a shallow hole.
