TECWERK ER 16 collet (Type 426 E) — 1 mm precision clamping sleeve

The TECWERK ER 16 collet (1 mm, type 426 E) is a compact, high-precision clamping sleeve for ER 16 collet chucks, designed for demanding toolholding in metalworking applications.

• Precision runout 5 µm
• Full-length tool retention
• Compatible with DIN 6499-B systems
• Clamping diameter compensation: nominal − 0.5 mm

Achieve consistent concentricity for improved surface quality and tool life

The collet delivers a guaranteed runout and repeatability of 5 µm, which translates directly into improved surface finish and prolonged cutter life. Tight concentricity reduces vibration and tool deflection during high-precision machining, so parts are produced closer to tolerance first time. By choosing a clamping sleeve with documented runout performance, process stability and downstream inspection effort are reduced, supporting more efficient production cycles and fewer rejects.

Secure retention and straightforward integration with ER 16 systems

Designed according to DIN 6499-B, the clamping sleeve fits standard ER 16 collet chucks and requires no intermediate sizing. The tool is held along the full clamping length, and the sleeve can also be clamped on the chamfer when needed, which simplifies set-up for both short and slightly protruding tools. This combination of compatibility and full-length retention ensures reliable gripping across a range of tool geometries and reduces the need for frequent rework or adjustment.

Compact dimensions and clear clamping guidance for everyday use

With overall length 27 mm, nominal clamping diameter 1 mm and outer diameter 17 mm, the collet is optimised for compact toolholders and tight working envelopes. The effective clamping compensation is nominal minus 0.5 mm, a practical rule to ensure the correct fit and avoid overstressing the sleeve. Supplied per unit, the component is ready for immediate use and simple to inspect: visual checks for wear and verification of runout in the chuck are sufficient to maintain reliable performance over many cycles.

FAQ

What runout performance can be expected from this collet?
The TECWERK ER 16 collet is specified with a runout and repeatability of 5 µm, providing high concentricity for precision machining.

Is this collet compatible with standard ER 16 chucks?
Yes — the clamping sleeve is manufactured to DIN 6499-B and is suitable for standard ER 16 collet chucks.

Can the tool be clamped on the chamfer with this collet?
Yes — the sleeve is designed so tools can be clamped along the full length or on the guiding chamfer when required.

How should the clamping diameter be chosen for a secure fit?
Use the nominal clamping diameter and account for the clamping compensation of nominal minus 0.5 mm to determine the proper fit and avoid overstress.

What are the key dimensions to check when selecting this component?
Verify the length 27 mm, nominal clamping diameter 1 mm and outer diameter 17 mm to ensure compatibility with the toolholder and tooling envelope.
