TECWERK ER collet ER 32/470 E — 15 mm clamping diameter, DIN 6499‑B

The TECWERK ER collet ER 32/470 E is a precision clamping collet for ER‑style collet chucks, engineered to secure tools along the entire clamping length in machining operations.

• DIN 6499‑B standardised profile
• Holds tools along full clamping length
• Runout and repeatability 5 µm
• Clamping diameter 15 mm nominal

Secure precision for repeatable machining

The collet conforms to the DIN 6499‑B profile, which ensures a defined interface to ER‑type chucks and consistent contact geometry. That standardisation, together with a specified runout and repeatability of 5 µm, reduces vibration and tool deflection, translating directly into improved surface finish and tighter dimensional control. The result is fewer rejects and less rework, making the clamping solution a rational choice for production environments where accuracy and throughput matter.

Built for compatibility and straightforward integration

Designed to engage with ER collet chucks, this clamping element accepts a 15 mm tool shank and offers an external form that matches common ER systems. With a length of L: 40 mm and an outer diameter of D: 33 mm, the geometry permits reliable seating in standard holders without requiring intermediate sizes. Because the tools are held along the full clamping length, stability is increased and sensitive tools can be clamped on the lead chamfer where necessary, simplifying setup and reducing handling time.

Faster setup and predictable clamping range

The collet bridges a clamping range described as the nominal diameter minus 1.0 mm; this clamping diameter bridging characteristic allows slight variations in shank size to be accommodated without changing the collet. That flexibility shortens machine downtime during tool changes and supports a steady production rhythm. The combination of secure axial grip and defined radial contact ensures predictable tool runout over repeated cycles, helping planners and operators to rely on stable process windows.

Practical reliability for everyday workshop use

Although tailored for ER‑style systems, the component’s design focuses on practical workshop demands: consistent repeatability, simple interchangeability and sturdy engagement with the tool shank. The specification supports a wide range of routine milling and drilling tasks where axial stability and radial precision are required. For businesses seeking accessible precision, this collet aligns with the ethos of supply partners who prioritise dependable stock and quality control.

FAQ

What tolerance can be expected for runout with this collet?
The specified runout and repeatability for the TECWERK ER collet ER 32/470 E is 5 µm, providing a reliable baseline for precision machining.

Can the collet compensate for slight variations in tool shank diameter?
Yes. The clamping diameter bridging feature (nominal minus 1.0 mm) allows the collet to accommodate small shank deviations without replacing the collet.

Is this collet compatible with standard ER chucks?
The collet is manufactured to the DIN 6499‑B form and is suitable for use with ER‑style collet chucks that accept the ER 32/470 E specification.

What are the key dimensions to check for holder compatibility?
Relevant dimensions are d = 15 mm, L = 40 mm and D = 33 mm; these determine seating and axial engagement in the holder.
