TECWERK ER collet Type ER 40/472 E — 22 mm clamping diameter

The TECWERK ER collet Type ER 40/472 E is a precision ER collet engineered for secure, repeatable toolholding in machining centres and ER collet chucks.

• Conforms to DIN 6499-B
• 5 µm runout and repeatability
• Holds tools along full clamping length
• 22 mm nominal clamping diameter

Maximise machining accuracy through consistent holding

The TECWERK ER collet is designed for precision toolholding where repeatability matters. Its adherence to DIN 6499-B guarantees dimensional compatibility with standard ER collet systems, while the specified 5 µm runout and repeatability minimise part deviation and tool vibration during cutting. For production runs and setups where tolerances are tight, the combination of standard conformity and low runout translates into fewer rejected parts and longer tool life, supporting reliable throughput on milling and machining applications.

Faster set-ups and secure grip reduce machining interruptions

Clamping is simplified by the ability to grip tools along the full clamping length, enabling stable contact and reducing axial and radial play. The collet permits clamping on the guiding chamfer and covers intermediate sizes by a bridging nominal minus 1.0 mm, lowering the need for multiple intermediate collet sizes and accelerating changeovers. These characteristics shorten preparation time and reduce inventory complexity, which benefits workshop efficiency and keeps production moving with fewer interruptions.

Built for compatibility and clear specification in the workshop

Specified dimensions and measurable data make integration straightforward: the collet delivers a compact footprint while providing defined performance. Key dimensional values such as L: 46 mm and D: 41 mm support correct selection for existing chucks and toolholders, and the nominal 22 mm clamping diameter is suitable for a broad range of tooling. The simple, standard-based design ensures the ER collet is a practical choice for both maintenance of existing equipment and upgrade paths in small to medium production environments.
