Description

Techleader ER20 Ultra Precision Collet 0.0002″ / 5um

We use high grade spring steel for all our collets

We put our slits into our new ultra precision collets with our new creep feed grinder.

This creates a more precise and even gripping collet.

Then we perfectly heat treated.

Then we precision ground for new higher accuracy of 0.0002″ / 5um TIR.

All our collets 100% inspected.
