Collet ER11
The ER 11 collet is designed to clamp cutting tools (drill bits, milling cutters) with a cylindrical shank in spindle units of drilling machines and CNC machining centers. It has a through hole and is characterized by reliable fixation, due to the presence of two clamping zones. The catalog of our online store presents a selection of ER 11 collets of different sizes from the Taiwanese manufacturer - HD Woodworking Tools.
