ER collet chuck DIN 69871 Form AD, SK40, clamping range 3–26 mm by TECWERK

The ER collet chuck DIN 69871 Form AD is a SK40 taper toolholder designed for secure clamping of cylindrical‑shank tools in machining spindles and CNC interfaces.

• DIN 69871 Form AD taper compatibility
• Wide clamping range 3–26 mm
• SK40 mounting with ER 40 retention
• Compact 63 mm body, 80 mm projection

Boosted spindle performance through standardised clamping

The ER collet chuck offers a combination of standard conformity and practical performance: thanks to the DIN 69871 Form AD steep taper and the ER 40 interface, the holder provides a repeatable clamping solution that minimises setup time. The design supports quick tool changes while maintaining concentricity, which contributes directly to reduced cycle times and consistent machining quality. Emphasis on industry standards ensures compatibility with common spindle tapers and collet sets, supporting predictable process control.

Flexible toolholding for mixed production

With a clamping range of 3–26 mm, this chuck accommodates a broad spectrum of cylindrical shank tools specified to DIN 6499, from small cutters to larger drills. The SK40 mounting delivers a secure spindle interface for medium‑duty applications, while the compact 63 mm body keeps overhang low to improve rigidity. This versatility reduces the number of different holders required in the tool cupboard, simplifying logistics and increasing floor productivity.

Compact form for improved rigidity and access

A short projection of 80 mm and a diameter of 63 mm concentrate mass close to the spindle nose, which helps preserve stiffness on the tool‑workpiece axis. The compact footprint also eases access when working in crowded fixturing or multi‑axis setups. The standard dimensions permit straightforward replacement and interchange in existing toolholding systems without lengthy machine downtime, supporting uninterrupted production workflows.

Practical selection and workshop guidance

The chuck is intended for machining shops and production departments that rely on standardised toolholding for repeatable results. Selection is guided by the tool shank diameter and the required projection to maintain rigidity; the ER collet system provides incremental sizes for close tolerance gripping. If clarification is needed on compatibility with specific collet sets or spindle interfaces, Metav Werkzeuge offers technical advice and application suggestions to ensure the holder matches the intended machining tasks.
