Work Stops for Precision Length Control

HQC® Quick-Change Solid Collet Stops

The solid stop threads into the collet body or draw bar adapter and locks against a shoulder. The purpose of the stop is to eliminate push back of the workpiece during drilling and roughing operations. If length control is required due to variation of the chucking diameter the Dead-Length Spider Stop Assembly may be used. (I6C only)
