Importantly, users can continue employing standard ER collets while upgrading to the precision collets, says ITC.
The collet chucks have a thick chuck wall design and strong outer form that increases rigidity and lowers vibration for longer spindle and tool life. Simultaneously, ITC says that the 6 to 20 mm collets have a sealed design that provides good coolant delivery.
The Widia universal collet is available with Safe-Lock pull-out protection from Haimer. Here, helical grooves in the shank of the tool combine with the respective pin drivers in the chuck to prevent the tool from spinning or being pulled from the holder under extreme machining conditions.
