TECWERK ER 40 (472 E) Collet Set, 4–26 mm clamping range

The Spannzangensatz ER 40 (472 E) is a complete ER40 collet set designed for use with collet chucks, offering a continuous clamping span from small to medium diameters and a high standard of runout control

• ER40 compatibility, 4–26 mm clamping range
• Runout and repeatability 5 µm
• Supplied in wooden base for secure storage

Reliable precision that reduces rework and set-up time

The set delivers consistent clamping with a specified runout and repeatability of 5 µm, which translates into measurable benefits on the shop floor: fewer scrap parts, reduced rework and tighter tolerances during milling or turning operations. For production environments where repeatability is essential, the collets offer a stable grip that keeps workpieces concentric under cut. The technical tolerance quoted indicates the typical deviation of spindle concentricity when the collet is correctly seated in a collet chuck, providing a clear reference for process control.

Compact organisation and durable storage for busy workshops

Presented in a wooden base, the set keeps individual collets organised and protected between shifts. The compact footprint supports efficient bench or cabinet storage, while the solid base minimises movement during transport. The 4–26 mm clamping span covers a broad range of common diameters, limiting the need for multiple partial sets and reducing changeover time. Clear labelling and arranged slots speed up tool selection and help maintain a tidy workflow on busy production lines.

Designed for ER40 chucks and straightforward integration into tooling stations

Compatibility with ER40 collet chucks ensures straightforward integration into existing tooling systems without modification. The set is intended for conventional clamping tasks where controlled concentricity and reliable repeatability are required; it suits both manual and CNC setups that accept ER40 tooling. The overall design emphasises practical workshop use: secure retention in the chuck, ease of replacement and stable clamping under moderate cutting forces, all of which contribute to predictable machining results.
