|Name||Drill Chuck Adapter|
3.carbon depth >0.8
4.integrated design of the rob and collet,can avoid the collet and rob separate
5.High accuracy,strong grasp force,and high stability
6.Easy broken parts are dealt by quenching
7.Self-tightening,grasp the collet slightly,when drilling,graso force is enhancing with the torque increasing and develop obvious strong grasp force to prevent the drill remove.
