Milling extension V-694B – ER16M taper, ST20x100L shank, Vertex

Milling extension V-694B for extended-reach machining and flexible clamping with an integrated collet set, designed for precision tasks where depth access and stability are required

• ER16M taper for secure clamping
• ST20x100L shank for extended reach
• Includes collet set for versatile tool sizes
• Robust design, approx. 1.1 kg per set

Achieve accurate cuts with rigid clamping

The design centres on stable tool clamping to reduce runout and maintain repeatable results during milling. The ER16M interface provides a compact, mechanically secure connection between tool and spindle, while the integrated collets allow clamping of various tool shanks without additional adapters. Reduced axial play and consistent clamping force translate directly into improved surface finish and longer tool life—attributes that matter when tolerances are tight and batch consistency is required.

Reach deeper features with confidence

The ST20x100L designation indicates the shank geometry and an extended length for accessing recessed or deep features. Longer reach minimises the need for additional setups or special tooling, enabling more operations to be completed in a single machine cycle. The extended configuration is particularly suitable for cavities, pockets and stepped profiles where standard holders cannot reach without compromising rigidity.

Less downtime through a complete collet set

Supplied as an 8-piece set, the kit combines the extension with a range of collets to cover common shank diameters, reducing tool changes and procurement complexity. A single, multi-size set streamlines workshop logistics and lowers the risk of incompatibility between holders and cutters. The consolidated solution supports faster changeovers and a leaner tool inventory for production environments.

Compatibility that fits existing toolchains

The holder suits setups accepting an ER16M taper, making it compatible with many standard milling spindles and toolholders. This compatibility ensures straightforward integration into existing toolchains and machine fleets without extensive modification. Machine shops benefit from predictable mounting and straightforward interchangeability when replacing or upgrading tooling systems.

Built for daily workshop use

At roughly 1.1 kg per set, the construction balances robustness and handling; the weight contributes to stable operation without being cumbersome during tool changes. The compact form factor supports ergonomic handling at the bench and safe, repeatable clamping cycles on the machine. Mechanical simplicity reduces maintenance needs and keeps the focus on productive machining.

Practical advantages for production environments

Combining secure clamping, extended reach and a matched collet assortment, this solution supports efficient, high-quality milling operations. The configuration reduces process steps, improves machining accuracy and helps maintain consistent part quality—rational benefits that lower rework rates and improve throughput in serial and bespoke production alike. The SKU V-694B reflects a ready-to-fit package that simplifies procurement and deployment.
