High-precision ER collets with internal square made from hardened spring steel for maximum accuracy and durability. Compliant with DIN 6499 standards, our collets ensure excellent concentricity (≤0.010 mm), strong clamping force, and reliable performance in all standard ER collet chucks. Ideal for milling, drilling, and general machining applications.

Achieve high precision and secure tool holding with our premium ER Collet Chucks. Designed for versatility and durability, these chucks ensure optimal performance in milling, drilling, and CNC machining applications. Compatible with a wide range of ER collet sizes (DIN 6499 / ISO 15488), they offer excellent concentricity and vibration resistance for superior machining accuracy.

The S3D Synchro Chuck from Bilz is a cutting-edge, synchronized rotary index chuck designed for use in 5-axis machining applications. This innovative tooling solution provides unparalleled accuracy and efficiency, enabling machinists to produce complex parts with precision and speed.

Features:
• Minimum length compensation in compression and tension direction.
• Ball bearing mounted (i.e. torque independent) suspension.
• Suitable for internal coolant supply up to 80 bar.
• Suitable for taps and thread formers.
• Suitable for right-hand and left-hand threads.
• Optimized spring-damper technology (± 0.5mm).
• 3D Synchro completely encapsulated function chamber (washable up to 80°C).
• Optimized seal (comparable to IP68).
