21mm Collet 5C Precision Collet, 0.02mm Runout Accuracy - Vertex

Take advantage of the combination of high concentricity (0.02 mm), a 21 mm nominal diameter and a compact 87 mm length for consistent, low-setup machining. Order the collet directly via Metav Werkzeuge or consult the team for application advice.

5C collet — 21 mm precision clamping sleeve by Vertex

The 5C collet is a precision clamping sleeve designed for secure toolholding in machining environments where repeatable concentricity and compact reach are required.

• 21 mm nominal diameter
• Concentricity 0.02 mm accuracy
• Length 87 mm for deeper reach
• Manufacturer Vertex

Precision that reduces rework and cycle variation

A concentricity specification of 0.02 mm provides a measurable basis for improved machining accuracy. Reduced radial runout means less vibration and lower risk of dimensional deviation during turning or milling, which translates into fewer rejects and less rework. The combination of tight concentricity and a 21 mm bore is beneficial where small tolerances are mandatory; the result is a more stable spindle behaviour and predictable part quality. The stated accuracy is a clear, verifiable performance indicator for process control.

Compact design for reliable clamping and accessible tool placement

With a length of 87 mm and a weight of 0.21 kg, the collet offers a balance between secure clamping and compact installation. The shorter profile helps to reduce overhang and improve rigidity in the toolholder, supporting higher cutting stability. Mass is kept low to avoid unnecessary spindle load while maintaining robust clamping force. In practice, this means longer tool life and reduced tool-change downtime where access and space are limited.

Material-neutral specification and workshop integration

As a component from Vertex, the collet is intended for integration into standard 5C toolholding systems and workshop workflows that require reliable repeatability. The item is identified by SKU 5C-21 and can be referenced directly for procurement and inventory. Where exact material compatibility is relevant, process engineers can align clamping choice with tooling and workpiece materials to ensure optimal cutting performance and safety. Clear data such as diameter, length and accuracy allow straightforward comparison during purchasing and process planning.
