TECWERK ER 32 collet – clamping diameter 14 mm, runout 5 µm

TECWERK ER 32 collet for ER collet chucks, designed to provide rigid tool retention and precision clamping in workshop and production environments

• DIN 6499‑B compatibility for ER chucks
• Full-length clamping for secure tool retention
• Runout and repeatability: 5 µm
• Clamping diameter bridging: nominal −1.0 mm

Precision standards that reduce setup time and scrap

The TECWERK ER 32 collet is manufactured to DIN 6499‑B dimensions, ensuring straightforward interchangeability with standard ER collet chucks. Adherence to the standard simplifies spindle tooling management and reduces the need for special adaptors. The specified runout and repeatability of 5 µm translate into tighter tolerances on finished components, fewer rejects and more consistent batch quality. For operations where repeatability and predictable tool behaviour are essential, the standard compliance delivers measurable production benefits.

Improved rigidity and tool life through full‑length clamping

Because the insert holds tools along the full clamping length, cutting forces are distributed more evenly and lateral play is minimised. This full‑length clamping capability, together with the option to clamp on the lead‑in chamfer, reduces vibration and tool deflection during milling, drilling and finishing passes. The result is prolonged cutter life and more stable machining, which supports higher material removal rates and lower total tool costs over time.

Flexible handling of tool diameter variations and compact dimensions

The collet allows clamping diameter bridging of nominal −1.0 mm, so small mismatches between nominal tool shank sizes can be accommodated without intermediate sizes. This feature streamlines tooling inventories and quickens changeovers. Compact physical dimensions (L: 40 mm, d: 14 mm, D: 33 mm) make the insert suitable for standard ER 32 applications where space is limited but precision is required. The compact design supports straightforward storage and fast replacement in a production setting.

Practical advantages for procurement and workshop workflows

Standardisation with the ER system reduces supplier complexity and eases procurement: the collet fits established ER fixtures and can be stocked as a modular component. The clear technical specification and measurable tolerances support purchasing decisions based on performance metrics rather than subjective claims. For workshops seeking to democratise precision—achieving dependable measurement and clamping quality without excessive overhead—the use of standard, well‑specified components contributes directly to operational reliability.
