ER 32/470 E Collet, 2 mm (TECWERK) – ER 32 clamping solution with 40 mm length

A ER 32/470 E Collet engineered for precision clamping in ER 32 collet chucks, ideal for small-diameter cutters and high-repeatability setups

• Compatible with ER 32 chucks (DIN 6499-B)
• Holds tools along full clamping length
• Runout accuracy of 5 µm
• Designed for nominal 2 mm clamping diameter

Precision and repeatability for critical machining

The ER 32/470 E collet is designed to deliver precision where tolerances matter. Conformance to DIN 6499-B ensures predictable fit in ER 32 collet chucks, while the specified runout 5 µm reflects the level of concentricity that can be expected in a correctly set-up spindle. Such repeatability reduces scrap and minimises secondary operations, improving throughput in batch production. The clamping system keeps cutting tools stable by holding them over the full clamping length, which limits deflection during deeper cuts and supports consistent surface finish.

Practical advantages for small-diameter tooling

This clamping solution addresses common challenges when working with small tools: the clamping range bridging capability (nominal minus 0.5 mm) allows secure gripping even when the nominal size is slightly undersized, which helps when tool wear or slight sizing variances occur. Physical dimensions—L: 40 mm, D: 33 mm, shank d: 2 mm—are optimised for compact tool setups and fit standard ER 32 fixtures without intermediate spacers. The collet can be used on the lead-in chamfer, enabling straightforward insertion and consistent seating during assembly, which saves time during tool changes and reduces the risk of misalignment.

Reliability in workshop and production environments

Built for repeatable clamping cycles, the collet supports stable machining in both jobbing and production contexts. Retention along the whole clamping length prevents partial gripping that can cause chatter; the result is fewer reworks and longer tool life. For procurement and process planning, this solution integrates into existing ER 32 toolholding systems without requiring adapter modifications. For complex setups or specific material applications, Metav’s specialists can provide targeted advice to ensure the clamping choice aligns with process parameters and spindle characteristics, supporting smooth integration into the workflow.

FAQ

What tolerance can be expected for concentricity with this collet?
The TECWERK ER 32/470 E collet is specified with a runout of 5 µm, which describes the concentricity performance under correct assembly and standard operating conditions.

Is this collet compatible with standard ER 32 chucks?
Yes, the collet conforms to DIN 6499-B and is intended for use with ER 32 collet chucks in standard toolholding systems.

Can the collet grip tools that are slightly undersized?
The clamping design permits a bridging of the clamping range down to nominal minus 0.5 mm, allowing secure gripping of tools that are marginally below nominal size.

What are the key dimensions to check for machine integration?
Important dimensions are L: 40 mm, D: 33 mm and the nominal clamping diameter 2 mm; these determine fit and compatibility with existing ER 32 fixtures.

Is the collet suitable for high-repeatability production runs?
Yes, the full-length retention and defined runout performance of the ER 32/470 E collet support high-repeatability production and reduced rework.
