Spannzangenfutter ER DIN 69871AD – TECWERK ER collet chuck, SK40, 2–20 mm clamping range

The Spannzangenfutter ER DIN 69871AD is a SK40 collet chuck designed for secure clamping of cylindrical-shank tools in machining centres and milling spindles.

*DIN 69871 Form AD compatibility *SK40 taper for high rigidity *Clamping range 2–20 mm versatility

Precision and rigidity that support tight tolerances

The TECWERK collet chuck is built to the DIN 69871 Form AD standard, providing a steep taper that increases axial support and reduces deflection during cutting. With a SK40 interface and a 100 mm projection, the holder maintains precision over extended reaches. These mechanical properties convert into consistent concentricity and repeatability, which are essential when machining to tight tolerances or working with fine finishing operations.

Versatile clamping for a wide range of tools

Engineered around an ER32 collet system, the toolholder covers a 2–20 mm clamping range, enabling one holder to serve a broad spectrum of cylindrical-shank cutters and drills. Compatibility with collets made to DIN 6499 simplifies tool inventory and allows rapid tool changes without compromising concentricity. The result is efficient setup times and fewer holders required for mixed production runs.

Seamless integration with standard spindles and setups

The holder’s interface is specified for common machine tapers and includes the listing Aufnahme: ER 32 / 470 E 1, making it straightforward to fit into conventional SK40 spindles. The clearly defined dimensions — projection A: 100 mm and body D: 50 mm — assist in workspace planning and collision checks. This compatibility means straightforward retrofits and predictable behaviour across different machines and fixtures.

Robustness and workshop practicality for everyday use

Manufactured for industrial workshop conditions, the chuck offers practical durability while remaining serviceable: routine inspection of the collet seat and cleaning of the taper preserve toolholding performance over time. The compact body and defined interface minimise handling complexity and support a tidy tooling configuration. As a product from TECWERK, it is intended for machinists and workshops that prioritise dependable clamping under continuous operation.
