V-694A Milling Extension with Collets (ST20×100L, ER16M) by Vertex

A V-694A milling extension with collets, engineered to provide increased reach and stable toolholding for CNC milling and precision workshop applications

• Extended reach ST20×100L
• ER16M taper for high rigidity
• Supplied as a 10-piece set

Reach deeper pockets with steady performance

The elongation provided by the ST20×100L configuration enables machining of deep cavities and complex geometries without compromising process reliability. The extended shank reduces the need for multiple tool changes and facilitates single-pass operations where access is limited. This results in more efficient cycle times and fewer interruptions on the machine; the design balances reach and stiffness to keep runout and vibration low for a predictable surface finish.

Clamping stability that preserves accuracy

A taper specified as ER16M gives the extension secure collet clamping, translating to improved concentricity and repeatability during milling. Combined with a compact overall mass of 0.9 kg, the assembly offers a compromise between inertial damping and dynamic response, helping to control chatter in a range of feeds and speeds. The integrated collet system ensures axial and radial retention suited to common milling operations, supporting consistent component tolerances and reducing rework.

Practical supply and workshop integration

Delivered as a 10-piece set, the extension simplifies stock management and ensures matching components are available for serial jobs. The set format reduces logistics overhead and supports rapid tool replacement where uptime is critical. Designed by Vertex, the product aligns with professionals seeking dependable tooling solutions that are straightforward to specify and quick to deploy — ideal for production shops and service departments that prioritise continuity and traceability.
