Frequently Asked Questions

What is the LYNDEX-NIKKEN ER20 sealed coolant collet used for?

The LYNDEX-NIKKEN ER20 sealed coolant collet is used in CNC machining centers for through-tool coolant applications. It holds cutting tools securely while allowing coolant to flow through the collet and tool, improving chip evacuation and cooling during high-speed milling, drilling, and tapping operations.

What are the specifications of the LYNDEX-NIKKEN collet E20-021(C)?

The LYNDEX-NIKKEN collet model E20-021(C) is a sealed ER20 coolant collet with a 21/64 in capacity. It is designed for ER20 collet chucks and provides sealed coolant capability for through-spindle coolant systems. The manufacturer part number is E20-021(C) and the brand is LYNDEX-NIKKEN.

Where to buy LYNDEX-NIKKEN collets worldwide?

You can source LYNDEX-NIKKEN collets worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the E20-021(C) sealed ER20 coolant collet.

How to select the correct ER20 collet size for a tool?

To select the correct ER20 collet, measure the tool shank diameter precisely. The collet capacity must match the shank size; for example, the LYNDEX-NIKKEN E20-021(C) fits a 21/64 in shank. Always use a collet within its clamping range and ensure it is sealed for coolant applications if required.
