and endurance, cleaness better, antirust, accuracy more stable, surface more
smooth, feel comfortable, appearance nice.
How to install the collet nut?
Operation is shown in the figure above
1. Put the collets into the nut, turn the collets slightly. Push
it into the nut at the offered direction evenly when the offset flange sinks

will break).
3. When changing the tool. Loosen the nut and it shall bring out
the collets and the cutter together. And then draw the cutter out push out
slightly the collets in the offered direction, it shall be ready for any change of
the cutter.
Features:
The special structure is for balance to make sure the status of circular uniform distribution.
The collets chuck will not be loosened during machining, and please assemble and disassemble the chuck as the marked direction
