TECWERK ER 11 Collet – 2 mm clamping, L: 18 mm

A TECWERK ER 11 collet 2 mm designed for ER collet chucks, offering DIN 6499-B compliance and full-length tool retention for consistent concentricity.

• DIN 6499-B compatible
• Full-length clamping for secure grip
• Runout and repeatability 5 µm
• Length 18 mm, clamping Ø 2 mm

Precision that reduces rework and improves part quality

The ER 11 clamping sleeve delivers a measurable benefit where concentricity matters: a specified runout of 5 µm ensures that cutting tools and gauges rotate with minimal eccentricity, which directly reduces surface variation and rework rates. The design provides full-length clamping, so the tool shank is retained along its active length rather than at a single point; this increases rigidity and helps maintain cutting geometry under load. The span bridging capability of nominal − 0.5 mm allows secure clamping even when minor diameter deviations occur, making the component suitable for repeatable, high-precision tasks.

Compatibility and quick setup for efficient workflows

Conformity with DIN 6499-B means straightforward interchangeability with standard ER chucks, eliminating guesswork at the machine spindle. The compact external diameter (D: 11.5 mm) and overall length 18 mm keep the clamping system compact while still offering robust retention. Because no intermediate gauges are required, changeovers are faster and less error-prone; the combination of standard dimensions and direct clamping reduces setup time and supports higher machine uptime. These features translate into a practical productivity gain on the shop floor.

Robust handling and confidence in everyday use

The collet's construction holds tools over the entire clamping length and allows clamping on the lead-in chamfer, which reduces slippage and distributes clamping forces evenly. This results in a secure grip that supports both interrupted cuts and continuous operation, promoting tool life and process stability. For workshops seeking dependable components, the compact clamping Ø 2 mm format and consistent repeatability deliver quiet assurance: fewer unexpected tool failures, steadier part quality, and predictable maintenance intervals.
