Milling Extension V-697B — ST20x100L with ER20 compatibility (Vertex)

The Milling Extension V-697B is a toolholder extension that increases reach and secures ER20-clamped tooling for milling operations and machining centres.

• ER20 collet compatibility for secure clamping
• ST20x100L shank for extended reach
• Supplied as a set of 10 items
• Robust 1.1 kg construction for stability

Increased reach while maintaining cut quality

A reliable tool extension must preserve machining accuracy at greater distances from the spindle. The ST20x100L specification provides extended reach while the mass of 1.1 kg helps to dampen vibration, reducing undesirable tool deflection. This combination supports stable cutting conditions on longer overhangs, which in turn contributes to consistent surface finish and tool life. The extension is designed for integration into standard milling setups, enabling deeper access to complex contours without the need for multiple tool changes.

Secure clamping and straightforward compatibility

Clamping is a decisive factor for repeatable results. The V-697B uses the ER20M collet standard, offering broad compatibility with common tool shank diameters and ensuring uniform radial pressure for reliable concentricity. ER20 systems are widely adopted in CNC environments; their spring-steel collets centre the tool shank and facilitate rapid changeover, which reduces downtime between operations. The design focuses on secure gripping and predictable behaviour under cutting loads, making it suitable for both roughing and finishing passes when set up correctly.

Set configuration and production-ready reliability

Supplied as a set of 10, the extension supports workshop logistics and planned tool inventories, simplifying batch tooling strategies and spares management. The item is produced by Vertex, a brand with recognised competence in toolholding solutions, and is intended for routine integration into milling tool sets. For procurement and supply continuity, Metav Werkzeuge acts as a European quality filter and distributor, offering consistent availability and pragmatic delivery from Emmerich. The combination of standard interfaces and a complete set reduces the need for frequent special orders and assists in maintaining uninterrupted production flow.
