• 100% inspection for concentricity, runout, and hardness.

• Compatible with all major CNC collet holders and spindle systems.

• Each ER32 collet and ER40 collet chuck undergoes strict balance testing to ensure safe high-speed operation.

FAQ – Frequently Asked Questions

Q1: What does “ER” stand for in ER Collet?
ER stands for “Elastic Rego-Fix,” originally designed by Rego-Fix in Switzerland, now the international standard for tool clamping systems.

Q2: How do I choose the right ER collet size?
Select according to your tool shank diameter. For instance, ER32 collet covers tools from 2–20 mm, while ER16 collet suits smaller diameters up to 10 mm.

Q3: What is the accuracy tolerance of your ER collets?
Standard precision is ≤0.005 mm, while ultra-precision types are available upon request.

Q4: Can I customize collets with my brand logo or special material?
Yes, as a custom ER collet manufacturer, we offer OEM/ODM branding and customized material or coating options.

Q5: Are your ER collets compatible with international machines?
Absolutely. Our ER collet holders fit all standard CNC toolholders, including BT, CAT, HSK, and ISO types.

Whether you require a collet ER 32, ER40 collet chuck, or a complete ER collet chuck set, our precision-engineered tooling solutions deliver unmatched reliability, accuracy, and lifespan.
As a professional ER collet manufacturer, we support global OEM buyers, distributors, and machining centers with consistent quality and fast delivery.
