Milling extension with collets V-693B — ER16M taper, ST20x50L shank (Vertex)

A Milling extension with collets engineered to extend tool reach while maintaining high rotational accuracy for CNC milling and shop-floor operations

• Secure clamping with ER16M taper
• Compact ST20x50L shank profile
• Supplied as an eight-piece set
• Precision SKU V-693B for order

Stable clamping for consistent machining

The design relies on an ER16M taper to provide secure tool holding and reduced runout, resulting in improved repeatability during milling cycles. By transferring clamping forces directly through a stable taper, the assembly supports consistent radial rigidity and helps maintain surface finish and dimensional accuracy. This benefit is particularly relevant where tool overhang is extended and vibration must be controlled to protect both the tool and the workpiece.

Set configuration to increase workshop flexibility

Supplied as an eight-piece set, the configuration offers immediate availability of multiple extensions for varied tasks and quick replacement of worn items. The set format reduces machine downtime and supports efficient changeovers in batch production. Traceability through the V-693B SKU and clear labelling simplifies inventory management in a busy workshop environment, supporting streamlined operational planning.

Clear specifications to support integration into existing tooling

The designation ST20x50L identifies the shank specification used for mounting and clearance planning, while the visible ER16M marking ensures compatibility checks against collets and holders. The compact mass (approx. 1 kg for the set) limits added inertia on the spindle, helping to preserve spindle bearings and maintain toolpath fidelity. The component is produced under Vertex quality standards and intended for integration into precision machining workflows where predictable behaviour under load is required.

FAQ

What is included in the set? The V-693B is supplied as an eight-piece set configured for extended milling applications and labelled for easy identification.

Which taper is used for clamping? Clamping is achieved via the ER16M taper, a standard interface that ensures secure engagement with ER16 collets.

What does the designation ST20x50L refer to? ST20x50L denotes the shank specification for mounting and reach considerations, indicating the nominal shank size and the extension length.

Is this suitable for precision milling applications? Yes, the combination of the ER16M taper and the compact shank profile supports stable tool holding and consistent machining performance under typical milling conditions.

How can the product be identified for ordering? Order using SKU V-693B or GTIN 4061905086144; both references match the Vertex milling extension with collets for procurement and stock control.
