Collet chuck V-109 — ER‑25, 42 mm (Vertex)

A collet chuck engineered for secure, concentric clamping in CNC and milling applications

• Compact 42 mm profile
• ER‑25 taper for standard collets
• Lightweight 0.7 kg spindle load reduction
• Precision clamping for repeatable centring

Consistent concentricity for accurate machining

The combination of the ER‑25 taper and a tight 42 mm footprint delivers a clamping solution that prioritises concentricity and repeatability. This design reduces run-out and lowers the risk of rework, translating into higher first-pass yields on precision components. The mechanism is suitable for machine shops that require stable, repeatable engagement between tool and workpiece; in-process errors are minimised and batch consistency is improved through reliable centring.

Lower inertia for faster cycle performance

With a mass of 0.7 kg, this toolholder reduces spindle inertia compared with heavier alternatives, helping to accelerate spindle speed changes and cut cycle times in dynamic machining sequences. Reduced rotating mass lessens wear on bearings and helps maintain balance at elevated speeds, while the compact diameter contributes to unobstructed tool access in confined fixturing situations. The net effect is a measurable gain in throughput without compromising clamping integrity.

Robust design for dependable workshop use

Built to integrate with standard collet systems, the unit offers a straightforward mechanical interface that supports routine production demands. The proven geometry of the clamping interface delivers consistent gripping force over repeated cycles, supporting predictable tool life and fewer setup adjustments. The association with Vertex underlines a track record of industrial manufacturing standards and straightforward interchangeability with existing ER‑25 collets and accessories.

Seamless integration and reduced setup time

Designed for quick installation on compatible spindles, the chuck simplifies changeover and minimises machine downtime. The compact 42 mm form factor allows closer tool spacing and easier access in multi-tool arrangements, while the ER‑25 compatibility ensures a wide choice of collets for different shank sizes. The result is a solution that enhances workshop flexibility and helps maintain flow on mixed-production or small-batch runs.
