TECWERK ER 16 collet — 6 mm clamping diameter, DIN 6499‑B compliant

The ER 16 collet (Type 426 E, 6 mm) is a precision clamping insert for ER collet chucks, engineered to deliver concentricity and secure grip across the entire clamping length.

• DIN 6499‑B compliant precision
• Secure clamping across full length
• Runout accuracy 5 µm
• Compact length L 27 mm, 6 mm bore

High repeatability for consistent machining results

The collet is designed to provide consistent concentricity, ensuring that every clamped tool or workpiece runs true. Compliant with DIN 6499‑B, the component guarantees a defined interface and dimensional conformity with ER‑type chucks, which simplifies tool selection and quality control. The specified runout / repeatability of 5 µm minimises vibration and tool wobble, translating directly into better surface finish and longer tool life. This measurable performance is a sound basis for process stability in small to medium batch production.

Reduced set‑up time through full‑length clamping

Because the insert is held along the whole clamping length, the need for re‑positioning or additional support is reduced. The design permits clamping on the lead‑in chamfer as well as on the straight bore, so tools with slight dimensional deviations can still be secured without bespoke intermediate sizes. The resulting efficiency lowers fixture complexity and shortens machine downtime between operations, supporting faster changeovers and higher overall equipment effectiveness.

Compact design that fits existing ER systems

With a nominal clamping diameter of 6 mm, length L 27 mm and an external diameter of 17 mm, the collet integrates cleanly into standard ER 16 toolholders. The clamping range bridging (nominal minus 1.0 mm) provides practical tolerance compensation for common workshop situations, allowing a single insert to accommodate small diameter variants. The compact footprint helps maintain access in tight tool spindles and keeps the centre of gravity close to the chuck, which is beneficial for dynamic balance and higher spindle speeds.

Practical benefits for workshop and production environments

The straightforward compatibility with ER chucks and the absence of required intermediate sizes make procurement and inventory management simpler. The combination of standard compliance, 5 µm concentricity and full‑length holding reduces scrap rates and inspection time, delivering a clear cost‑efficiency argument for workshops aiming to democratise precision. For applications where reproducible clamping and predictable machining outcomes matter, this ER collet is a robust, low‑complexity choice.

FAQ

Is this collet compatible with standard ER 16 chucks?
Yes. The TECWERK ER 16 collet (Type 426 E, 6 mm) is manufactured to fit ER‑type collet chucks in accordance with DIN 6499‑B.

What clamping accuracy can be expected with this insert?
The collet delivers a runout and repeatability of 5 µm, which supports high concentricity applications and improved surface finish.

Can the collet be used to grip along the full tool length?
Yes. The design allows the tool to be held across the full clamping length and it can also be clamped on the lead‑in chamfer when appropriate.

Which dimensions should be checked before installation?
Key measurements are clamping diameter 6 mm, length L 27 mm, external diameter 17 mm, and the bridging allowance of nominal minus 1.0 mm for close tolerances.

Are intermediate sizes necessary when the workpiece differs slightly?
No intermediate sizes are required; the design permits bridging of up to nominal minus 1.0 mm, simplifying tool selection.
