ER 32/470 E collet – 7 mm clamping diameter, 5 µm runout (TECWERK)

A robust ER 32/470 E collet designed for accurate tool clamping in ER32 collet chucks across machining and workshop applications.

• High runout accuracy 5 µm
• Compatible with ER32 collet chucks
• Full-length clamping including lead chamfer
• Clamping bridging nominal −1.0 mm

Precision clamping for predictable machining results

The collet is manufactured to meet standardised form and fit criteria, delivering 5 µm roundness and repeatability that translate directly into tighter tolerances and reduced scrap rates. With a defined 7 mm clamping diameter, the component offers a stable grip on cylindrical tooling, which is essential for repeatable drilling and milling operations. The adherence to recognised dimensional norms ensures the clamping element is compatible with established ER32 systems, allowing it to be integrated without adaptation into existing setups and supporting efficient production planning.

Secure hold over the full clamping length reduces setup risk

Because the design allows the tool to be held along the full clamping length, the clamping force is distributed evenly and tool whirling is minimised. The ability to engage the workpiece or tool on the lead chamfer increases seating reliability for slightly tapered or chamfered shanks. The specified clamping bridging: nominal −1.0 mm explains how the collet compensates for small diameter deviations while maintaining grip, so changeovers and in-process variations are better managed and the need for intermediate sizes is largely removed.

Standard conformity and simple integration speed production

Produced in accordance with DIN 6499‑B, the collet fits conventional ER32 chucks without further adjustment, reducing setup time and the risk of assembly errors. The compact dimensions support tight tool stacks and smaller work envelopes while maintaining performance: consistent holding across runs helps to optimise tool life and machine throughput. The clear technical specification and compatibility make the collet a pragmatic choice for workshops and production environments seeking reliable clamping without complex retrofit work.
