4mm 5C Collet High Precision 0.02mm Runout, 87mm Length - Vertex

Take advantage of the combination of precise 0.02 mm accuracy, a compact 4 mm clamping diameter and an 87 mm length for dependable, repeatable gripping in machining operations; order directly via Metav Werkzeuge or consult our specialists for tailored advice.

5C Collet – Precision clamping, 4 mm diameter, 87 mm length (Vertex)

The 5C Collet is a precision clamping sleeve designed for secure holding of 4 mm shanks in standard 5C toolholders and collet chucks, suited to machine shops and toolrooms requiring repeatable tolerance control.

• Precision grip for 4 mm shanks
• Compatible with 5C system fixtures
• High concentricity: 0.02 mm accuracy
• Compact 87 mm length for deeper holding

Consistent concentricity for better surface finish

High-precision machining depends on stable workholding. With a 0.02 mm indicated accuracy, this collet delivers reliable concentricity that reduces runout and improves surface quality. The exact grip on a 4 mm shank minimises vibration and uneven wear, which in turn supports longer tool life and fewer reworks. This performance-oriented behaviour is particularly valuable in short-run production and precision finishing where tolerance adherence is critical.

Fits established 5C tooling to speed up setup

Designed for the 5C system, the component integrates with standard collet chucks and fixtures, enabling rapid changeover and straightforward retrofitting in existing setups. The 87 mm length offers a deeper engagement for improved axial support when compared with shorter sleeves, helping to stabilise slender tools or small workpieces. Operational efficiency rises from predictable clamping behaviour and reduced alignment checks during batch production.

Built for dependable workshop use

Manufactured to Vertex's industrial standards, the collet combines balanced geometry with a mass of 0.21 kg that contributes to smooth rotation and reduced imbalance at moderate spindle speeds. The robust design principle supports continuous use in machine shops and inspection stations, ensuring repeatable performance across cycles. Maintenance is minimal when paired with routine inspection, allowing the tool to retain precision over extended service intervals.

FAQ

What diameter does the collet accept?
The collet accepts a 4 mm shank; the 4 mm specification is indicated for the 5C collet (SKU 5C-4) by Vertex.

What concentricity or runout can be expected?
A runout tolerance of approximately 0.02 mm is specified, which supports precise concentric clamping and consistent machining results with the Vertex 5C collet.

Which tooling system is this compatible with?
The item is compatible with the 5C system and fits standard 5C chucks and fixtures commonly used in lathes and toolroom equipment.

Which machines can make use of this collet?
Suitable for use in conventional and CNC lathes, milling setups using 5C tooling, and general toolroom fixtures where a 4 mm clamping diameter is required.

How should the collet be maintained to preserve accuracy?
Regular cleaning of the clamping surfaces, inspection for wear or burrs, and light lubrication of mating threads preserve accuracy; replace the collet if deformation or excessive runout is detected to maintain machining quality.
