V-744 Collet Chuck — ER-20 steep taper, 34 mm diameter (Vertex)

The V-744 is a precision collet chuck designed for secure clamping of ER collets in compact machining setups and general clamping technology applications.

• Steep ER-20 taper for stable clamping
• Suitable for standard ER collets
• 34 mm outer diameter for compact setups
• Robust 4.8 kg construction for rigidity

Built for consistent, repeatable clamping across batches

The steep ER-20 taper is engineered to centre ER collets precisely, reducing axial runout and promoting consistent tool performance. This design reduces micro-movement between spindle and toolholder, which in turn lowers tool wear and improves surface finish on serial production. The compact 34 mm profile makes the chuck suitable for tight-tooling environments where space is limited yet high repeatability is required. By translating the mechanical features into measurable outcomes — reduced rework and longer tool life — the clamping solution supports efficient shop-floor processes and predictable cycle times.

Optimised rigidity and vibration control for demanding operations

With a mass of 4.8 kg, the chuck provides added inertia that helps dampen vibration during aggressive cuts or interrupted machining. The heavier build contributes directly to process stability, allowing higher material removal rates without loss of control. The construction focuses on long-term reliability: stable clamping geometry combined with a steep taper reduces settling and maintains repeatability over extended production runs. For operations where productivity and part quality are paramount, this clamping system delivers tangible performance advantages that translate into lower scrap rates and improved throughput.

Straightforward compatibility and application guidance

Designed for use with standard ER collets, the chuck integrates into existing clamping toolchains without complex adapters. The ER-20 taper classification ensures compatibility with widely available collet sizes and accessory ranges, simplifying inventory management. Where uncertainty exists about fitment or intended application, Metav Werkzeuge provides technical guidance to match clamping solutions to machining centres and turning heads. The Vertex manufacturing pedigree underpins the design intent: a focused clamping solution that balances compactness, secure clamping, and workshop practicality.

FAQ

What collet system does this chuck accept?
The Vertex V-744 accepts standard ER collets and is specified for use with ER-20 taper collets.

Is the chuck suitable for heavy-duty milling?
The 4.8 kg construction of the chuck provides increased inertia and improved vibration damping, making it appropriate for many demanding milling tasks within its clamping category.

How does the ER-20 taper affect runout and tool life?
The ER-20 steep taper in this chuck improves centring and reduces axial runout, which helps extend tool life and improve surface finish during serial production.

Can the chuck be used on compact machines with limited spindle clearance?
The 34 mm diameter profile is designed for compact setups and tight tooling envelopes, allowing integration where space is restricted.

Where can technical documentation for the V-744 be obtained?
Technical specifications and dimensional drawings are available through Metav Werkzeuge; contact the sales team for detailed documentation.
