According to Widia, the collet chuck has the ability to continue using standard ER collets while upgrading to precision collets. It also has thicker chuck walls and a stronger outer form for added rigidity and lower vibration for longer spindle and tool life, the company adds. The universal precision collet is available with safe-lock pull-out protection from Haimer.

Helical grooves are ground into the shank of the milling tool that, together with the respective pin drivers in the chuck, prevent the tool from spinning or being pulled out of the holder altogether under extreme machining conditions, the supplier notes. The helical path of the safe-lock grooves is said to allow for adjusting tool length, meaning tools can be reground and pre-set as usual.
