Spannzange Typ ER 40/472 E Spann‑D.18mm TECWERK — ER collet, 18 mm clamping diameter, 5 µm runout

A bold and compact collet solution, the Spannzange Typ ER 40/472 E Spann‑D.18mm TECWERK is engineered for secure tool retention in ER collet chucks used across general workshop and industrial machining applications

• DIN 6499‑B standard compliance
• 5 µm runout and repeatability
• Clamping diameter 18 mm
• Length L 46 mm for secure hold

Accurate clamping that raises machining consistency

The collet offers 5 µm runout, a figure that directly improves part quality by reducing radial error at the tool tip. Runout describes the deviation of the rotating tool axis from true centre; a low figure means cuts are concentric and tool wear is reduced. Certified to DIN 6499‑B, this clamping sleeve ensures repeatable results in batch production and shortens quality checks, so setups stay consistent between shifts and operators.

Designed for seamless integration with ER systems

Built to fit standard ER collet chucks, the unit provides full‑length holding so tools are gripped along the entire clamping area rather than only at the nose. That design improves stability under load and allows clamping on the lead chamfer where required. The specification notes a clamping bridge of nominal minus 1.0 mm, which clarifies the usable range when selecting matching tool shanks and avoids unnecessary rework during tool changes.

Practical dimensions and workshop benefits

Key dimensions such as L: 46 mm, d: 18 mm and D: 41 mm support a compact tool envelope while delivering robust retention. The compact form factor reduces interference in tight setups and permits deeper insertion without compromising grip. Together with the DIN standard and low runout, these characteristics reduce cycle interruptions, lower scrap rates and increase machine uptime—advantages that deliver measurable efficiency gains on the shop floor.
