Collet Type ER 40/472 E – clamping Ø 10 mm (TECWERK)

The ER 40/472 E collet, clamping Ø 10 mm, is a precision ER40 collet designed for secure tool clamping in ER collet chucks across milling and drilling applications.

• Complies with DIN 6499-B
• Full-length clamping for secure hold
• Runout and repeatability 5 µm
• Clamping diameter bridging: nominal minus 1.0 mm

Precision that reduces rework and tool wear

The collet is manufactured to the DIN 6499-B standard and delivers a runout and repeatability of 5 µm, ensuring consistent concentricity for rotating tools. This level of accuracy reduces vibration and uneven tool wear, which in turn lowers scrap rates and extends tool life. For operations where concentric accuracy directly affects surface finish and tolerance adherence, the precise behaviour of this clamping element translates into measurable productivity gains and fewer corrective machining steps.

Design that speeds set-up and cuts inventory

Thanks to full-length clamping, tools are gripped along their effective length and may be clamped on the lead chamfer; this improves axial support and reduces the need for intermediate shims or adapters. The collet bridges the clamping diameter by nominal minus 1.0 mm, so a single nominal size can accommodate small variations without additional parts. The compact dimensions (L: 46 mm, d: 10 mm, D: 41 mm) make the component easy to store and identify, simplifying toolroom logistics and accelerating changeovers at the machine spindle.

Simple integration and practical applications

The component is intended for use in ER collet chucks and mates directly with standard ER tooling systems. As an ER 40 unit, it is suited to medium-duty machining tasks where a 10 mm clamping diameter is required. The secure hold over the entire clamping length improves repeatability between setups, which benefits batch production and series work. For teams new to collet technology, the functional principle is straightforward: the tapered collet compresses uniformly when tightened in the chuck, producing a concentric grip that is both stable and repeatable.
