Milling extension set V-691B by Vertex — ER11M taper and ST16×50L shank

V-691B milling extension set designed to extend tool reach and maintain machining precision for CNC milling and finishing operations

• ER11M taper for secure clamping
• Precision shank ST16×50L for extended reach
• Includes collets for low runout and stability
• Robust set tailored for CNC milling workflows

Precision clamping that reduces rework and scrap

The extension set employs an ER11M taper interface combined with matched collets, delivering consistent clamping force and therefore low runout. Reduced runout translates into improved dimensional accuracy and better surface finish, cutting down on rework and scrap rates. For production environments where repeatability matters, this combination supports tighter tolerances and predictable outcomes.

Extended reach without sacrificing rigidity

A ST16×50L shank provides additional reach for pockets and deep features while preserving lateral stiffness essential for stable cutting. The modest mass (approx. 0.5 kg) balances increased reach with acceptable dynamic behaviour, helping to avoid chatter during medium-duty milling. This makes the extension suitable where access limitations would otherwise require tool compromises, enabling efficient machining without altering cutter selection.

Compatible with standard toolholders to streamline workflows

Designed as a practical accessory for toolroom and production use, the set integrates with common ER11-compatible toolholders and collet chucks, supporting straightforward installation and quick collet changes. The configuration reduces tool-change frequency in specific tasks, promoting higher machine utilisation and shorter cycle times. The Vertex origin signals industry-level manufacturing practices, providing confidence in repeatable performance.

Practical handling and workshop benefits

The set simplifies setup routines: matching collets ensure concentricity and minimise adjustment time, while the extension design permits flexible tool arrangements where fixed-length cutters are unsuitable. For mixed production runs or prototype work, this adaptability supports faster process iteration and less downtime. Pairing the component with Metav Werkzeuge’s supply and advisory services ensures consistent availability and documentation for traceable procurement.
