TECWERK ER 11 collet – 3 mm bore, 5 µm runout

A TECWERK ER 11 collet for secure clamping of small cutting tools and rotary instruments in ER collet chucks, suitable for workshop and light production use.

• ER 11 collet for 3 mm nominal diameter
• Conforms to DIN 6499‑B standard
• Holds tools along entire clamping length
• Runout and repeatability 5 µm

Accuracy that reduces rework and keeps processes stable

The collet is manufactured to meet DIN 6499‑B, delivering consistent concentricity and minimal deviation. With a specified runout and repeatability of 5 µm, the component supports high‑quality finishing and reduces scrap rates in serial operations. The documented bridging capacity (nominal minus 0.5 mm) allows machining slightly undersized shanks without intermediate adaptors, simplifying tool selection and reducing changeover complexity while maintaining the expected positional precision.

Stable grip along the full clamping length for safer machining

Raised clamping contact across the full clamping length ensures that small‑diameter tools benefit from better support, lowering the risk of deflection and premature wear. The design also permits clamping on the lead‑in chamfer, enabling secure seating even when tools present a guiding bevel. As a result, cycle stability in milling or drilling tasks improves and tool life is extended, supporting predictable production throughput without frequent manual adjustments.

Compact dimensions for tight setups and micro‑tooling

Compact geometry makes the item a strong choice where space is restricted. With L: 18 mm, d: 3 mm and D: 11.5 mm, the collet fits typical ER 11 systems while allowing close tool spacing and reduced interference in crowded toolholders. This small footprint benefits workshops that run high‑density fixtures or require frequent tool changes, making it simpler to configure heads and spindles for micromachining tasks without compromising clamping security.

Practical compatibility and supply reliability for everyday use

Designed to fit standard ER collet chucks, the component eliminates the need for intermediate sizes and is suitable for many common materials and operations where small shank tools are used. Supplied via Metav’s distribution, customers gain the advantage of a dependable stock flow and a quality filter in Europe that keeps consistent items available for workshop and light industrial users.
