TECWERK ER 32 collet ER 32/470 E – 6 mm clamping diameter, L 40 mm

A TECWERK ER 32 collet ER 32/470 E designed for secure clamping of 6 mm tools in standard ER collet chucks, providing consistent concentricity for production and workshop use

• DIN 6499-B standard compliance
• Holds tools along full clamping length
• Runout and repeatability 5 µm
• Suitable for 6 mm clamping diameter

Consistent concentricity that cuts rework time

High-precision machining relies on stable tool alignment; the 5 µm specification for runout and repeatability means less scrap and fewer rejects in serial production. This level of concentricity reduces tool vibration and improves surface finish, which in turn lowers secondary operations such as regrinding or polishing. For users installing the collet in series production or frequent changeover scenarios, the predictable tolerance performance translates directly into shorter setup verification and more uptime on the machine.

Secure grip across the entire tool shank for safer cutting

The collet clamps along the full clamping length, so the tool is supported more completely than with short-contact systems. That continuous contact makes cutting forces distribute evenly, reducing the risk of chatter and extending tool life. Because the sleeve can also be engaged on the lead chamfer, short shanks and partial-support tools can still be held reliably. The specification for clamping diameter bridging (nominal minus 1.0 mm) further improves flexibility when slight diameter differences occur, avoiding unnecessary downtimes for regrinding or shimming.

Fast compatibility and reduced setup complexity

Manufactured to DIN 6499-B, the design ensures straightforward interchangeability with standard ER collet chucks; no intermediate sizes are required. The compact dimensions L 40 mm, d 6 mm and D 33 mm make the component easy to handle and install, while the standardised form factor simplifies inventory management. For workshops and small-scale production facilities this standardisation reduces the variety of spares needed and accelerates tool changes, supporting lean processes and efficient throughput.

Built for workshop and production environments

As an ER 32 clamping solution, this sleeve suits applications from light milling to more demanding turning and drilling operations where a reliable grip is essential. Its construction and tolerance focus supports repeatable performance across multiple shifts. Combined with Metav’s philosophy of making precision accessible, the component offers a pragmatic balance of industrial compatibility and everyday usability — a practical choice for maintenance departments, contract manufacturers and precision toolrooms seeking dependable clamping without unnecessary complexity.
