Frequently Asked Questions

1. What is an ER Steel Sealed Collet? ▼

ER Steel Sealed Collets are precision collets with a built-in sealing design that prevents coolant from leaking through the slots, making them ideal for high-pressure coolant applications.

2. Where are sealed collets commonly used? ▼

These collets are mainly used in CNC machining, especially where through-tool coolant delivery is required for deep drilling or high-speed cutting operations.

3. What is the main benefit of using sealed collets over standard collets? ▼

Sealed collets maintain a leak-free coolant path, reducing coolant loss and improving tool life, chip evacuation, and machining accuracy.

4. Are ER Steel Sealed Collets compatible with standard ER holders? ▼

Yes, they are designed to fit standard ER collet chucks but only support tools with solid shanks (no coolant-through holes).

5. How do I maintain ER sealed collets? ▼

Wipe clean after each use, inspect the seal regularly, and avoid excessive tightening. Store in a dry location to prevent corrosion.
