TECWERK ER collet chuck – 16 mm shank, 1–7 mm clamping range

A TECWERK ER collet chuck designed to clamp cylindrical-shank tools securely in ER collets, suitable for general workshop and light production use

• ER 11 collet interface, DIN 6499 compatible
• Cylindrical shank D 16 mm, shank length 150 mm
• Clamping range 1–7 mm for small-diameter tools

Precise clamping for repeatable machining outcomes

The ER 11 interface in this collet chuck provides a high degree of concentricity, making it suitable for operations where runout and repeatability matter. With a clamping range of 1–7 mm, the chuck accommodates a wide selection of small drills, reamers and end mills, while ensuring secure axial grip. The design minimises vibration and improves surface finish by keeping radial runout low; this is a practical advantage for shorter tools and fine-detail work. The compact size and standard interface also support straightforward replacement of worn collets and predictable tool behaviour across production runs.

Robust shank and geometry for stable toolholding

Built with a cylindrical shank (D 16 mm) and a lateral clamping surface, the chuck offers stable seating in toolholders and spindles that accept a 16 mm straight shank. The extended shank length (150 mm) and an indicated L1: 20 mm datum allow reliable axial positioning and force transmission during cutting. Compatibility with collets to DIN 6499 simplifies integration into existing fixtures and reduces the need for special adaptors. This construction translates directly into less tool chatter, improved dimensional control and a consistent feel during machining tasks.

Practical benefits for workshops and small production runs

The compact form factor and standardised interface make this chuck a pragmatic choice for machining shops, maintenance departments and toolrooms that require fast changeovers and dependable clamping of small-diameter tools. The mechanical simplicity supports low-maintenance operation and easy inspection; worn or damaged collets can be replaced quickly to restore original performance. For operations aiming to reduce downtime and maintain consistent part quality, the combination of ER collet technology and a straight 16 mm shank offers a balanced solution between flexibility and stability.

FAQ

Which collet series fits this chuck?
The chuck uses ER 11 collets in accordance with DIN 6499, so ER 11 collets sized for the required tool diameters are compatible with the TECWERK ER collet chuck (SKU 2120619001NW).

What tool diameters can be clamped?
The clamping range is 1–7 mm, allowing secure holding of small drills, reamers and miniature end mills within that diameter span when the appropriate ER 11 collet is fitted.

Is the chuck suitable for heavy milling operations?
This collet chuck is optimised for small-diameter toolholding and light to moderate machining; for heavy milling with larger cutters, a chuck with a larger interface or different clamping concept would be more suitable than the TECWERK ER collet chuck.

How does the 16 mm shank affect installation?
The 16 mm cylindrical shank provides a standardised mounting diameter for toolholders and adaptors; its length and lateral clamping surface support stable seating and simple integration into compatible spindles or adaptors.

Can worn collets be replaced to restore performance?
Yes, replacing worn ER 11 collets restores clamping accuracy and concentricity; the chuck is designed for routine collet replacement to maintain consistent machining quality.
