Collet ER 32/470 E – clamping Ø 11 mm (TECWERK)

Collet ER 32/470 E is a precision ER 32 collet engineered for secure toolholding in milling and drilling operations, compatible with ER 32 collet chucks.

• DIN 6499-B standard compliance
• High runout repeatability 5 µm
• Full-length tool retention
• Clamping diameter 11 mm, length 40 mm

Precision clamping for consistent machining

The ER 32 collet is manufactured to deliver stable toolholding with a documented roundness and repeatability of 5 µm, which translates into fewer rejected parts and longer tool life. Conformance to DIN 6499-B provides a verifiable standard for interchangeability and quality, giving procurement and production planners a factual basis for integration. Tight runout control reduces vibration and improves surface finish, making the component well suited for high-precision tasks in series production and job-shop environments. This level of accuracy supports predictable machining cycles and fewer rework stages.

Seamless integration with existing ER 32 systems

Designed to mate with standard ER 32 chucks, the collet accepts an 11 mm clamping diameter and bridges minor size differences (nominal minus 1.0 mm) without intermediate adapters. Tools are gripped along the full clamping length, and the geometry permits clamping on the lead chamfer, simplifying setup when facing slightly varying tool shanks. The compatibility reduces changeover complexity and eliminates the need for special sizing rings, supporting efficient tooling logistics and straightforward retrofit into current toolholding assemblies.

Robust handling and quick set-up for workshop routines

With an overall length of 40 mm and an outer diameter of 33 mm, the collet balances compactness with sufficient gripping surface to maintain stability under load. The design ensures tools are held securely along their effective length, which helps maintain concentricity during heavy cuts and repeated cycles. Mechanical handling is intuitive for qualified staff: insertion, compression and release follow established ER collet practices, so process familiarity shortens training time and minimises production interruptions.

Operational advantages that improve throughput

Reliable clamping and standardised dimensions contribute directly to cycle-time stability and reduced scrap rates. The combination of standard conformity, easy integration and measurable repeatability supports a rational investment decision: better part quality and reduced downstream inspection effort. For production planners and workshop managers, the collet represents a practical component that enhances process reliability while fitting existing ER 32 toolholding ecosystems.
