ER 16 Collet 426 E – 2 mm clamping diameter, high-precision (TECWERK)

The ER 16 Collet 426 E is a precision ER16 collet designed for secure tool clamping in standard ER collet chucks, suited to general machining and finishing tasks.

• DIN 6499‑B compatibility guaranteed
• High runout accuracy 5 µm
• Clamping diameter 2 mm
• Full-length tool retention

Precision that stabilises machining results

Accurate clamping reduces vibration and extends tool life. The collet delivers a verified runout of 5 µm, which significantly improves concentricity for small-diameter tooling and delicate finishes. Compatibility with the DIN 6499‑B standard means the collet integrates with established ER systems, providing a measurable improvement in repeatability and surface quality compared with generic clamping solutions. This level of precision supports tighter tolerances and more predictable production outcomes.

Secure grip along the entire clamping length

Reliable retention is achieved because the gripping force acts over the full clamping length, which reduces slippage and tool deflection in heavy or interrupted cuts. The collet can also be clamped on the guiding chamfer, offering flexibility when tools have reduced shank length. Key dimensions such as 2 mm clamping diameter, 27 mm length and 17 mm outer diameter contribute to a compact, stable interface that suits small-diameter drills and reamers while preserving spindle balance.

Easy integration into existing ER setups

Designed for ER16 chucks, this collet fits directly into common collet chucks without the need for intermediate adapters or special spacers, so machine downtime for tool changeover is minimised. The documented clamping-range bridging of nominal minus 1.0 mm describes how the collet accommodates slight tool-size variances while maintaining radial runout and repeatability. Supplied as a single unit, it is suitable for workshops and production cells that require dependable small-diameter clamping with minimal adjustment.

FAQ

What clamping diameter does this collet support?
The ER 16 Collet 426 E from TECWERK supports a 2 mm clamping diameter (SKU 2000832912NW), suitable for small-diameter drills and reamers.

How precise is the radial runout?
Radial runout and repeatability are specified at 5 µm, which helps to maintain concentricity and improve surface finish when using small tools.

Is the collet compatible with standard ER chucks?
Yes, it is DIN 6499‑B compatible and designed to fit ER16 collet chucks without adapters.

Can the collet hold tools on the guiding chamfer?
Yes, the design permits clamping on the guiding chamfer as well as along the full clamping length, providing flexibility for shortened shanks.

What are the key outer dimensions to check for clearance?
Length is 27 mm and outer diameter is 17 mm, which should be checked against chuck and spindle clearances.
