Collet ER 11/4008 E – ER11 collet, 5 mm, TECWERK

The ER 11/4008 E collet is a precision clamping sleeve designed for secure holding of 5 mm tool shanks in ER11 collet chucks, delivering high repeatability for machining and workshop applications

• DIN 6499-B standard compliance
• Suitable for ER collet chucks
• Full-length holding; clamps on chamfer
• Runout accuracy 5 µm

Precision that keeps processes stable

The primary benefit of this clamping sleeve is consistent concentricity: with a runout accuracy of 5 µm, cutters are held with tight concentricity, which reduces vibration and improves surface finish. The combination of full-length holding and uniform clamping pressure minimises axial and radial play, resulting in more predictable tool wear and fewer scrap parts. This stability is especially valuable in small-series production and precision workshop tasks where repeatability directly affects yield and downstream operations.

Proven compatibility and useful span bridging

Manufactured to DIN 6499-B, the collet integrates seamlessly with standard ER toolholders, ensuring reliable interchangeability across widely used clamping systems. The span diameter bridging: nominal −0.5 mm means the collet can safely bridge small gaps when a tool shank is slightly undersize, maintaining clamping force without additional shims. This feature simplifies tooling choices and reduces setup time, since intermediate sizing is not required and tools can be clamped on the guiding chamfer when appropriate.

Compact design for tight setups and quick changes

With compact dimensions (L: 18 mm, d: 5 mm, D: 11.5 mm) the sleeve is suited to confined tool zones and short overhang arrangements. The small footprint supports agile machine layouts and closer tool spacing on multi-spindle equipment. The ergonomic geometry also facilitates fast assembly and disassembly during tool changes, contributing to reduced machine downtime and more efficient workshop workflows.

Engineered reliability for everyday production

Built for repeatable performance in industrial and craft environments, this ER11 clamping sleeve delivers straightforward functionality without unnecessary complexity. The design keeps the tool held over the entire clamping length and permits clamping on the guiding chamfer, which together support secure, consistent gripping under machining loads. For procurement and process planners, the combination of standard compliance, compact form factor and measurable runout makes this an effective choice for precision workholding installations.
