ER 16 collet 426 E — 5 mm clamping diameter, TECWERK

A ER 16 collet 426 E engineered for secure clamping of 5 mm tools in standard ER chucks, suitable for precision machining and workshop production

*DIN 6499‑B compatibility for ER chucks *Full‑length clamping for secure tool hold *Runout and repeatability: 5 µm *Clamps on chamfer; compact length L 27 mm

Precise clamping for consistent machining results

The clamping sleeve delivers precision where it matters: a nominal clamping diameter of 5 mm combined with a documented runout / repeatability of 5 µm ensures tools are held concentrically, reducing vibration and improving surface finish. Compliance with DIN 6499‑B confirms dimensional and interface compatibility with common ER systems, simplifying integration into existing collet chucks. This technical reliability translates into fewer rejected parts and more predictable production cycles, a clear advantage in batch and serial manufacturing.

Secure hold and flexible seating for varied tool geometries

Designed for full‑length clamping, the sleeve grips the tool along the entire clamping surface so that short shanks and light tooling remain stable during operation. The ability to be clamped on the guiding chamfer increases versatility for tools that require seating on the lead‑in, while the specified span bridging (nominal minus 1.0 mm) allows the collet to accommodate slight undersize tolerances without intermediate adapters. With an overall length of L 27 mm and compact outer diameter, the component is suitable for confined toolholders and keeps the assembly profile low.

Reliable specification and practical workshop benefits

The collet's straightforward specification and proven interface minimise setup time: no intermediate sizes are required between standard tool diameters, and the geometry is intended to maintain concentricity over repeated changes. As a TECWERK clamping component supplied via Metav, it benefits from a distribution network focused on dependable stock levels and fast order processing. If additional technical clarifications are needed, the distribution team can advise on selection and compatibility to support uninterrupted workflow.

FAQ

Is this collet compatible with standard ER 16 chucks? Yes. The ER 16 collet 426 E is manufactured to the DIN 6499‑B interface and fits standard ER 16 collet chucks.

What clamping accuracy can be expected from this collet? The clamping sleeve offers a runout and repeatability specification of 5 µm under correct installation and good toolholder condition.

Can the collet grip tools on the chamfer? Yes. The design allows clamping on the guiding chamfer, enabling secure seating of tools with chamfered shanks.

What are the key dimensions to check when replacing a collet? Check clamping diameter (5 mm), overall length (L 27 mm) and outer diameter (D 17 mm); these dimensions ensure proper fit in the chuck and tool stability.

What does span bridging nominal minus 1.0 mm mean? It indicates the collet can close sufficiently to accommodate a tool that is up to 1.0 mm under the nominal diameter, providing flexibility for slight undersized tools.
