Llambrich CBB-16-J3 1-16mm Ball Bearing Keyed Drill Chuck, J-3 Mount

Llambrich CBB chucks are ball bearing keyed drill chucks with capacities up to 25mm. Llambrich describes them as drill chucks with key for production drilling equipment, with ball bearings in the tightening mechanism to reduce friction and help grip the drill shaft (manufacturer-stated).

Machine fitting is through Jacobs tapers, and the range takes tools of up to 25mm (1") (manufacturer-stated). The 13mm chuck has a J-3 or J-6 mount, the 16mm chuck a J-3, the 19mm chuck a J-4 and the 25mm chuck a J-5. Llambrich states that all the pieces are hardened and ground (manufacturer-stated).
