V-698B Milling extension with ER20M collet compatibility and 150 mm reach — Vertex

The V-698B is a milling extension designed for extended-reach milling and precision toolholding in CNC machining environments, offering a balance of reach and stability for demanding production tasks

• ER20M collet compatibility for secure clamping
• 150 mm extended reach for deep machining
• 1.2 kg mass for improved vibration damping
• Designed for CNC milling applications

Improve access without compromising rigidity

Extended-reach toolholding is often associated with loss of rigidity, but this milling extension is engineered to reduce that compromise. The combination of a longer working length and a substantial mass provides better vibration damping, which maintains cutting stability during deep or awkward toolpaths. As a result, machining cycles can proceed with fewer adjustments and improved first-pass accuracy, supporting higher process reliability and reduced scrap rates.

Consistent toolholding for accurate finishes

A central advantage of the design is its compatibility with ER20M collets, a widely used system for precise axial and radial clamping. The secure collet interface keeps runout low and repeatability high, which directly benefits surface finish and dimensional accuracy on finished parts. For shops upgrading tooling systems, the extension supports a wide range of cutter shanks while preserving the geometric integrity of the cut, translating technical precision into predictable production output.

Easy integration and dependable supply for production

Supplied as a complete set and finished to industrial standards, this toolholder integrates with common CNC spindles and existing tool-management routines. The component’s specification focuses on practical deployment in series production and prototype work alike, enabling shorter changeover times and simplified inventory management. Backed by Vertex’s manufacturing pedigree and Metav Werkzeuge’s distribution model, the product supports sustained availability and a clear path to procurement for engineering teams.
