Collet Type ER 32/470 E — ER 32 collet, clamping diameter 16 mm by TECWERK

The Collet Type ER 32/470 E is a high‑precision ER 32 clamping collet intended for secure tool holding in milling and drilling operations, compatible with standard ER 32 collet chucks.

• ER collet for ER 32 chucks, clamping Ø16 mm
• Manufactured to DIN 6499‑B standard
• Holds tools along full clamping length
• Runout repeatability up to 5 µm

Precision that reduces rework and improves cycle stability

The Collet Type ER 32/470 E is built to maintain tight tolerances in repetitive machining. Compliance with DIN 6499‑B guarantees dimensional conformity and interchangeability with ER 32 systems, while a specified runout repeatability of 5 µm minimises radial run‑out at the tool tip. These characteristics translate into fewer rejected parts, lower scrap rates and more predictable tool life. By reducing geometric variation at the spindle interface, the clamping solution contributes directly to reliable production quality.

Versatile clamping range that simplifies tooling logistics

With a nominal clamping diameter of 16 mm and a documented bridging capacity: nominal minus 1.0 mm, the collet covers small diameter tolerances without the immediate need for intermediate sizes. The design allows the tool to be clamped on the guiding chamfer and along the full clamping length, which enhances contact stability and reduces axial play. This adaptability supports quicker set‑ups and a reduced inventory of spare collets, streamlining workshop logistics and reducing machine downtime.

Robust geometry for dependable machining runs

Mechanical dimensions such as L: 40 mm, d: 16 mm and D: 33 mm define the collet’s operating envelope and its fit within ER 32 tooling systems. The construction keeps tools secured over the entire clamping face, distributing clamping forces to lower point stresses and limit deformation. The result is improved concentricity and repeatable tool positioning during high‑precision tasks. Where spindle performance and consistent part quality are priorities, this collet offers a measurable improvement in process stability.

Practical benefits for everyday workshop use

Designed for straightforward integration into ER 32 collet chucks, the component requires no unusual maintenance and can be handled with standard tooling practice. Because the clamping system supports the tool on the guide chamfer, the effective gripping zone is increased, which can reduce slippage under load and improve finish quality. The collet’s specification provides a clear, engineering‑centred basis for selecting the appropriate clamping solution when repeatability and accuracy matter.
