Collet ER 11/4008 E — ER 11 collet, 6 mm clamping diameter, TECWERK

Collet ER 11/4008 E for ER collet chucks, compatible with DIN 6499-B and designed for reliable full-length gripping of tools

• DIN 6499-B compatible ER collet
• Precise runout: 5 µm tolerance
• Clamping range: nominal −0.5 mm
• Compact length L 18 mm for ER chucks

Improved machining accuracy through concentric clamping

The ER 11 collet delivers a measurable improvement in concentricity thanks to a guaranteed 5 µm runout. This level of accuracy reduces vibration and uneven wear during turning and milling operations, which in turn preserves cutting edges and improves surface finish. The ability to maintain the tool along the full clamping length ensures stable support, especially when the tool is inserted to the guiding chamfer; the result is fewer reworks and a more predictable production output.

Seamless integration with ER 11 systems for workshop efficiency

Designed to the DIN 6499-B standard, this collet fits common ER collet chucks without requiring intermediate adjustments. With an effective clamping diameter 6 mm, an outer diameter of D 11.5 mm and a compact L 18 mm length, the component is suitable for tight setups where space and repeatability matter. Standardised dimensions speed up changeover times and make inventory management easier, supporting a leaner tooling strategy and fewer machine downtimes.

Practical benefits and handling explained

The specification “clamping bridge: Nennmaß minus 0.5 mm” indicates the collet’s capacity to grip slightly undersized tools, increasing flexibility across batches with small diameter tolerances. The short overall length aids access in confined holders while maintaining roundness under load, so operators can rely on consistent results. As a branded part from TECWERK, the collet combines standard conformity with practical handling features that suit everyday workshop demands.
