Zero Nut
The return-to-zero nut is the secret weapon of ultra-precision machining
In addition to the locking collet itself
Adjust the deflection accuracy of the tool through the "six" screws on the nut
Keep your reamers, drills, and milling cutters free from deflection after tool elongation
With AA grade collet
A total of 6 oil circuit screw holes

How to use
1. Loosen the screw first
2. After locking the tool, lock the adjusting screw on the side
3. Measure the current deflection accuracy of the tool to be zeroed
4. Adjust the deflection accuracy of the side screw to correct to the required accuracy
5. finish
