ER 32/470 E Collet (9 mm Clamping Diameter) — TECWERK ER 32 clamping collet with 40 mm length

A ER 32/470 E collet (9 mm) designed for secure, repeatable clamping in ER 32 collet chucks, suitable for precision toolholding in workshops and production environments.

• Precise 5 µm runout accuracy
• Full-length tool clamping capability
• Compatible with ER 32 collet chucks
• 9 mm nominal clamping diameter, 40 mm length

Consistent precision that reduces rework and scrap

The ER 32/470 E collet offers a documented runout and repeatability of 5 µm, which directly reduces tool vibration and improves surface finish. In practice, tighter runout means less tool deflection and more reliable hole and shaft tolerances, helping production processes meet stricter specifications with fewer rejects. For operations where part conformity is critical, this level of control supports higher first-pass yield and predictable machining results.

Secure grip along the full clamping length for stable machining

Tools are held along the entire clamping length, so the cutting tool receives even support across its shank rather than at a single point. This full-length engagement increases bending resistance and reduces chatter during milling or drilling. The collet can also be seated on the guiding chamfer, enabling secure clamping of tools with short shanks or slight runout, while the clamping diameter bridging (nominal minus 1.0 mm) provides practical tolerance for minor size deviations without interim sleeves.

Engineered for ER 32 systems and industry standards

Manufactured to DIN 6499‑B dimensions, the collet integrates seamlessly with ER 32 collet chucks and tooling systems. Compatibility with established standards ensures interchangeability and predictable behaviour when switching between toolholders and machines. The design removes the need for intermediate sizes, simplifying tool selection and reducing inventory complexity in busy workshops and service departments.

Practical dimensions and workshop benefits

Key dimensions—L: 40 mm, d: 9 mm, D: 33 mm—make this collet suitable for a wide range of general machining tasks, from drilling to light milling. The clear specification of geometric data allows straightforward verification and insertion into tool lists and CAM setups. When combined with standard ER 32 chucks, the collet supports rapid tool changes and stable operation, contributing to shorter setup times and improved overall equipment effectiveness.

FAQ

What level of runout precision can be expected from this collet?
The TECWERK ER 32/470 E collet delivers a runout and repeatability of 5 µm, ensuring tight concentricity for precision machining tasks.

Is the collet compatible with standard ER 32 chucks?
Yes, the collet is manufactured to DIN 6499‑B and is compatible with ER 32 collet chucks and corresponding systems.

Can shorter tools be clamped securely with this collet?
The design permits clamping on the guiding chamfer and provides full-length engagement, allowing secure holding of tools with shorter usable shanks.

What sizes does the collet cover and is an intermediate sleeve required?
The nominal clamping diameter is 9 mm and the design bridges up to nominal minus 1.0 mm, so intermediate sizes are not required for typical tolerance offsets.

Which dimensions are relevant when programming or setting up the machine?
Important values are L: 40 mm, d: 9 mm and D: 33 mm; these should be entered into tool lists and setup sheets for correct offsets and clearances.
