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

A Milling extension with collets V-693A engineered to extend tool reach while preserving clamping accuracy for ER16M taper applications.

• ER16M taper for standard collets
• ST20x50L configuration for extended reach
• Supplied as a 10-piece set
• Unit weight approx. 0.7 kg

Extend reach without sacrificing stability

The V-693A is designed to increase effective tool length while maintaining rigidity and repeatability on ER16M-equipped machines. The combination of an ST20x50L shank geometry and a short, robust body minimises deflection during axial extension; this preserves cutting performance and reduces the need for frequent tool changes. The ER16M interface ensures compatibility with common collets, allowing straightforward integration into existing toolholders. For production contexts where consistent positional accuracy is required, this extension offers a technical route to reach-in operations without compromising surface finish or dimensional control.

Consistent clamping for repeatable results

Clamping stability is achieved through the collet system supplied with the extension, delivering uniform radial pressure and concentricity. The use of standard collets reduces set-up variance and supports repeatable machining cycles, which is especially relevant in serial milling and light slotting operations. Supplied as a set of 10, the package supports batch processing and spare-part management, enabling predictable tool-change intervals and inventory planning. The extended tool configuration is particularly suited to workflows where reproducible clamping and minimal runout are prioritised over maximum overhang.

Ready-to-fit sets for efficient workshop integration

Each unit has been specified with practical workshop use in mind: a nominal weight of 0.7 kg per piece balances handling and mass damping, while the compact profile aids storage and tooling logistics. The supplied configuration anticipates common ER16M collet sizes and adapts to standard holder systems, easing procurement and reducing installation effort. As a Vertex product, the extension is intended for repeatable, production-oriented milling where the benefits of extended reach must be matched by predictable clamping behaviour and organised tooling supply. Integration into existing toolboards and racks is straightforward, supporting streamlined production set-up and quicker job turnover.

FAQ

Is the extension compatible with standard ER16 collets?
The extension uses an ER16M taper and is compatible with standard ER16 collets; the clamping system supplied with the Vertex V-693A fits common ER16 toolholders.

How many pieces are included in the delivery?
Delivery is as a set: the product is supplied as a 10-piece set, providing ready spares for serial production.

What is the nominal weight of a single unit?
A single extension weighs approximately 0.7 kg, which balances handling and vibration damping in typical milling use.

Can the extension be used to reach recessed features without sacrificing concentricity?
The design focuses on extended reach while maintaining rigidity and concentric clamping through the ER16M collet interface, supporting reach-in operations with stable runout.

How is the product identified for ordering and stock control?
Use the Article number V-693A and GTIN 4061905086601 for clear identification and procurement tracking.
