V-696B Milling Extension with ER20M Collets — ST20x50L | Vertex

The V-696B is a precision milling extension intended to extend tool reach in CNC milling and machining setups while preserving secure collet clamping and repeatable running accuracy.

• ER20M collet interface for standard toolholding
• Shank designation ST20x50L for extended reach
• Supplied as a set with collets for quick setup
• Robust construction with dependable repeatability

Better access without sacrificing precision

When machining deep pockets or recessed features, access often determines whether a part can be completed without secondary fixtures. This tool extension increases usable reach while keeping the cut in the original tool axis. The integrated ER20 clamping system maintains concentricity and reduces the need for frequent re‑setups, which supports predictable cycle times and less scrap. The result is a straightforward extension of capability that helps maintain throughput without complex fixture changes.

Secure clamping and consistent runout for repeatable results

The design centres on the ER20M collet interface, a widely used standard that provides a balance of clamping force and flexibility across common shank sizes. The ST20x50L designation identifies the shank form and extension length, enabling planners to match toolholders and spindle adapters precisely. As a complete set with collets, the unit simplifies tool preparation and reduces changeover steps. This combination supports sustained accuracy during production runs and helps conserve spindle performance by avoiding unnecessary tool swaps.

Streamlined integration into the workshop workflow

Supplied as a set, the extension reduces procurement complexity and accelerates machine readiness for standard milling tasks. For workshops scaling operations or preparing job‑specific toolkits, this package reduces the number of individual components to manage and ensures compatibility with existing ER20 toolholding systems. Metav Werkzeuge acts as a quality filter for the European market, providing logistical reliability from Emmerich and practical sourcing for industrial and trade customers. For specification checks or bespoke requirements, Metav’s technical consultants are available to advise on suitability and setup.
