Collet chuck V-402 — ER-20 interface, MK taper by Vertex

The Collet chuck V-402 is a compact ER-style chuck designed for secure clamping with an MK (Morse) taper shank, suitable for general milling and drilling workholding where space and repeatability matter

• ER-20 compatible collet interface
• MK taper shank for rigid spindle mounting
• 34 mm external diameter for compact setups
• Lightweight construction, approx. 0.3 kg

Reliable, repeatable workholding for production environments

The V-402 collet chuck combines an ER-20 interface with a compact external diameter to deliver consistent clamping in constrained spaces. The design reduces axial runout and improves repeatability, which is critical when multiple tools or inserts are changed frequently. By using standard ER collets, the chuck ensures predictable contact geometry; this reduces setup time and makes tolerance control easier across batches. The combination of a short, rigid body and precise taper engagement provides a stable connection between tool and spindle, supporting consistent finishes and dimensional accuracy on serial parts.

Faster cycles and reduced spindle load through efficient design

A lightweight toolholder with a 34 mm body helps to lower rotational inertia, which can translate into faster acceleration and deceleration during automated cycles. The V-402’s configuration supports reliable clamping force from ER collets while keeping mass to a minimum, helping to reduce strain on bearings and extend spindle life. In production terms this results in improved throughput and predictable maintenance intervals. The ER-20 interface also allows quick collet changes, which shortens tooling downtime and improves overall process efficiency without compromising holding strength.

Compatibility, serviceability and vendor reliability

The chuck is specified for ER collets with an MK shank, making it compatible with a wide range of machines that accept Morse taper toolholders. Routine inspection is straightforward: check collet seating and taper engagement for wear and clean contact surfaces to maintain low runout. The V-402 benefits from Vertex manufacturing standards and is distributed through Metav Werkzeuge, which acts as a quality filter for the European market; this ensures traceable supply and straightforward reordering for workshop fleets. For workshops seeking to centralise procurement, the compact toolholder is an easy-to-manage component in broader tooling kits.

FAQ

Is the V-402 compatible with standard ER collets?
The V-402 collet chuck is designed for use with standard ER-20 collets, allowing a broad range of collet sizes to be fitted for different tool diameters.

Which machine spindles accept the MK-mounted chuck?
The MK taper shank on this Vertex collet chuck fits spindles or adapters that accept the corresponding Morse taper size; verify the spindle taper before ordering.

How does the V-402 affect spindle wear and cycle times?
The lightweight 0.3 kg body reduces rotational inertia, which can improve acceleration and reduce stress on bearings, helping to maintain cycle efficiency and spindle life.

What maintenance is recommended for the collet chuck?
Regular cleaning of taper contact surfaces and inspection of collet seating in the V-402 will preserve low runout and consistent clamping; follow standard workshop maintenance practices.

Can the chuck be used for high-precision finishing operations?
With correctly matched ER collets and proper taper engagement, the Vertex V-402 supports high-precision setups by minimising runout and ensuring stable clamping.
