ER 11 (4008 E) Collet Set – 13-piece, 1–7 mm clamping range (TECWERK)

The ER 11 (4008 E) Collet Set is a compact clamping set designed for precision toolholding of small-diameter cutters and rotary tooling in workshops and production environments

• ER 11 system for small-diameter tooling
• Clamping range 1–7 mm in 0.5 mm steps
• Runout and repeatability: 5 µm
• Supplied in wooden storage base

Precision where it matters: consistent runout for repeatable machining

The ER 11 (4008 E) collet set is built to deliver consistent runout across a series of small tools, with documented 5 µm repeatability that supports high-accuracy operations. Such stability reduces tool chatter and vibration, which in turn improves surface finish and extends tool life. For manufacturing processes that require tight tolerances on small diameters, the predictable concentricity of these collets makes process control simpler and inspections more straightforward. Operators gain measurable process reliability without complex adjustments.

Organised tooling and fine gradation to reduce changeover time

Stored on a solid wooden base, the collets are presented in a clear sequence from 1–7 mm, including half-step increments (1.0, 1.5, 2.0 … 7.0 mm). This gradation minimises selection time during setup and ensures the correct clamping size is to hand, which helps reduce downtime between tool changes. The tactile wooden tray protects collet faces from damage while providing a compact, workshop-friendly footprint that keeps the bench organised and tooling traceable during multi-operation runs.

Compatibility and compact form for streamlined integration

Designed for ER11 chucks and standard ER collet chucks, the set integrates with most small spindle toolholders used in toolrooms and light production centres. The compact external dimensions of 85 x 20 x 95 mm make storage and transport straightforward, while the full set composition supports a range of drilling, milling and reaming operations on small diameters. The straightforward ER11 interface makes adoption simple for existing setups and supports repeatable clamping forces across the diameter range.

FAQ

What clamping diameters are covered by the set?
The set covers the 1–7 mm range in regular half-millimetre steps (1.0, 1.5, 2.0 … 7.0 mm), providing fine gradation for small-diameter tooling.

How accurate is the runout with these collets?
The TECWERK ER 11 (4008 E) collet set offers runout and repeatability of approximately 5 µm, suitable for high-precision small-scale machining.

Is the collet set compatible with standard ER11 chucks?
Yes — the collets are designed for the ER11 system and will fit ER11 collet chucks commonly used in toolholders and spindle noses.

How is the set supplied and stored?
The collets are supplied on a wooden storage base, which protects the collet faces and keeps components organised at the bench.

Which workshops benefit most from this collet set?
The ER11 collet set suits toolrooms, prototype shops and light production environments where small-diameter precision and quick changeovers are priorities.
