V-403 Collet Chuck for ER Collets with Morse Taper (ER-25, Ø42 mm)

The V-403 collet chuck provides rigid, repeatable clamping for ER collets on machines equipped with a Morse taper spindle, suited to tight fixtures and high-turnover set-ups.

• Compatible with ER-25 collets
• Morse taper shank for spindle mounting
• Compact Ø42 mm body for tight spaces

Secure clamping that improves machining consistency

The chuck is engineered for precision workholding using standard ER collets, delivering stable grip and repeatable positioning. By pairing the ER-25 interface with a rigid mounting form, the system reduces variability between setups and supports consistent component geometry across batches. This stability helps maintain tool life and process reliability while enabling measurable improvements in finishing and dimensional control.

Space-saving design that streamlines workshop layouts

A compact outer diameter of Ø42 mm and a lightened mass of 0.4 kg make the chuck suitable for crowded fixtures and multi-tool arrangements where clearance is limited. The Morse taper connection ensures firm axial and radial support with a simple, repeatable mounting routine, reducing downtime between tool changes. The small footprint supports denser tooling configurations without compromising on stability or concentricity.

Compatibility that speeds up changeovers and tool handling

Designed for use with ER collets, the chuck offers broad tooling versatility and straightforward collet swaps, promoting quick changeover during series production or tool trials. The system integrates into standard clamping workflows and is compatible with widely used ER collet sets, which minimises the need for special adapters and keeps inventory lean. This approach supports efficient production planning and faster reaction to order changes.

Reliable sourcing through a dedicated precision partner

Sourced from a recognised manufacturer and distributed by Metav Werkzeuge, the chuck benefits from a supply chain that emphasises availability and quality control. Purchasing via Metav brings access to a broad portfolio of compatible accessories and the reassurance of a quality filter based in Emmerich. This supply model supports uninterrupted production and reduces the administrative burden of multi-supplier procurement.

FAQ

Which collet series fits this chuck?
The V-403 accepts standard ER-25 collets, allowing use of common ER tooling for a wide range of tool diameters.

Can the chuck be mounted directly in a Morse taper spindle?
Yes. The chuck is supplied for mounting on spindles or adaptors with the corresponding Morse taper (MK) interface.

Is the chuck suitable for tight fixturing and compact setups?
Yes. With an outer diameter of 42 mm and a weight of 0.4 kg, the chuck is designed for use in confined fixtures and close-quarter tool arrangements.

How does this chuck affect setup repeatability?
By combining the ER-25 collet system with a Morse taper mount, the chuck provides stable axial and radial positioning, supporting improved repeatability across successive setups.

What is included for installation?
The chuck is delivered as the clamping unit compatible with ER-25 collets and intented for direct mounting on a matching Morse taper shank
