Preset stopper screw
Driving / retaining tooth
Important
• The preset stopper screw of the collet chuck
must be larger than the largest tool carried by the
spring collet size.
• Insert the tool only through the rear side of the
ER SURE collet, as the retaining tooth does not
enable inserting the tool from the front side.
