Milling extension with ER20M collets, ST25x100L — Vertex V-698C

The milling extension provides extended reach and stable clamping for precision machining tasks, suited to setups requiring ER20M collet compatibility and a ST25x100L shank.

• ER20M collet system compatibility
• ST25 x 100L shank for extended reach
• Supplied as a 12-piece set

Extended reach that preserves machining accuracy

The extension's design with an ST25x100L shank delivers greater tool reach without compromising concentricity, enabling access to deeper cavities and complex geometries. A predictable tool offset reduces rework and shortens setup times, while the compatibility with an ER20M collet system maintains secure clamping and low runout. This combination supports consistent surface quality and repeatable tolerances on milled components.

Ready-to-use set for efficient tool handling

Supplied as a 12-piece set, the kit simplifies inventory and tool-change processes in busy shops. Having multiple extensions available reduces machine downtime during batch runs and supports standardised setups across several machines. The overall set weight of 1.4 kg means compact storage and easy handling when organising tool cabinets or transport trays, helping to streamline day-to-day workshop logistics.

Compatibility and operational reliability in milling applications

Engineered for milling operations that require collet-mounted tooling, the extension fits into workflows using ER20M clamping interfaces and ST25 shanks. The robust mechanical interface supports high-speed rotation and steady cutting forces, which contributes to reliable chip formation and predictable tool life. Clear, standardised connections make this product straightforward to integrate into existing tool systems without special adapters.

Production benefits for precision-focused shops

Using a purpose-built milling extension helps to reduce fixture complexity and minimises the need for custom jaws or long overhang setups. The result is improved cycle stability and fewer rejects, translating into better overall process efficiency. For precision-focused workshops, the combination of extended reach and collet compatibility delivers tangible gains in throughput and quality assurance.
