Main Parameters Of Drill Chuck

The three main parameters of drill chuck are precision, clamping force and holding range.

The accuracy is used to control the run-out of the gripper-type tool to ensure the precision of the machining hole. The clamping force is to ensure that the gripper-type tool does not skid, and prevents the handle-type tool from slipping and unable to work. In general, the clamping precision on bench drill requires a little higher, and the clamping accuracy of the hand drill is relatively low. The clamping range is used to control the minimum and maximum diameter of the clamping tool to meet the requirements of the job. Under normal circumstances, the maximum clamping range is only 0 larger than the size of the chuck. 3mm or so. If the super too large, will greatly waste materials, improve the production cost of the Chuck.
