TECWERK Collet ER 25/430 E — Clamping Ø 10 mm, precision ER 25 collet

The TECWERK Collet ER 25/430 E is a precision clamping sleeve for ER 25 collet chucks, designed for rigid, repeatable tool holding in general workshop and light industrial applications.

• DIN 6499‑B standard compliance
• Fits ER 25 collet chucks
• Full‑length clamping of tools
• Runout and repeatability 5 µm

Consistent concentricity for improved machining quality

The ER25 collet is manufactured to DIN 6499‑B tolerances, which ensures the runout of 5 µm and a predictable concentricity that directly benefits surface finish and tool life. The ability to bridge small diameter deviations (clamping diameter bridging: nominal minus 1.0 mm) reduces the need for multiple intermediate sizes and shortens changeover time, providing a practical efficiency gain on production runs. This technical reliability translates into measurable process stability and less scrap in routine operations.

Compact form factor that preserves rigidity and balance

With a length of 34 mm, internal diameter 10 mm and external diameter 26 mm, the collet minimises tool overhang and helps maintain spindle stiffness. The short overall length contributes to reduced vibration and better balance at higher spindle speeds, while the design that holds tools over the whole clamping length improves axial support. These dimensional characteristics combine to offer both stable cutting conditions and straightforward handling during tool changes, supporting consistent cycle times and surface quality.

Practical compatibility and dependable supply chain

Designed specifically for ER 25 systems, the clamping sleeve requires no intermediate sizes and can be seated on the pilot chamfer for secure engagement. The practicality of a single‑piece supply (packaging unit 1) suits small workshop replenishment and controlled inventory management. Backing from Metav Werkzeuge provides a dependable procurement route: Metav’s European stock and quality screening aim to make high‑precision metrology and clamping solutions accessible, supported by a broad product range and long‑term market trust.

FAQ

What tolerance can be expected for concentricity with this collet?
The TECWERK ER 25/430 E collet is specified with a runout of 5 µm, delivering reliable concentricity for demanding tooling setups.

Is this collet compatible with standard ER 25 chucks?
Yes, the clamping sleeve is designed to fit ER 25 collet chucks and conforms to DIN 6499‑B dimensions for interchangeability.

How much diameter variation can the collet bridge when clamping?
The clamping diameter bridging is nominal minus 1.0 mm, allowing secure clamping of tools marginally undersize to the nominal diameter.

Can tools be clamped on the pilot chamfer with this collet?
Yes, the design permits clamping on the pilot chamfer, and tools are held along the full clamping length to enhance axial stability.

What are the main dimensions to check for spindle integration?
Key dimensions are length 34 mm, internal clamping diameter 10 mm and external diameter 26 mm; these ensure correct fit and minimal overhang.
