VDR-NT40I-A drawbar (630 mm, 5/8-11UNF) by Vertex

The VDR-NT40I-A drawbar secures NT40 tool holders in machine spindles, providing extended reach for deep-mounted fixtures and reliable clamping during machining.

• 630 mm length for extended reach
• 5/8-11UNF threaded connection
• Robust design by Vertex, weighs 1.3 kg

Improved tool retention for predictable machining results

A consistent clamping interface reduces tool run-out and the need for frequent adjustments. The drawbar principle converts spindle actuation into axial clamping, producing the repeatability required for tight tolerances. With a 630 mm overall length the component is suited to setups where tools sit deeper in the spindle or where fixtures require extra reach. The 5/8-11UNF thread delivers a standardised mechanical connection that supports stable transmission of clamping forces, limiting vibration and improving surface finish. These measurable properties help to cut rework and increase uptime in production environments.

Reliable design that simplifies maintenance and handling

Weight and geometry influence handling and replacement intervals. At 1.3 kg the shaft balances robustness with manageable handling for operators during maintenance or換out. The standardised threaded interface reduces tooling complexity and supports compatibility with established NT40 tool-holder systems. Where technical terms are unfamiliar: a drawbar is the axial rod inside the spindle that pulls and holds the tool holder by engaging the threaded section; the thread specification (5/8-11UNF) defines the mating connection and is critical for correct clamping action. The straightforward mechanical design means no electronics to fail and minimal upkeep beyond regular inspection.

Practical workflow benefits for workshops and production shops

Integrating a dependable clamping component supports faster tool changes and steadier processes, translating into lower scrap rates and predictable cycle times. The product’s Vertex provenance signals attention to manufacturing standards and component fit, which is particularly valuable for small and medium-sized workshops seeking industrial-grade reliability without complex procurement. Metav’s role as a quality filter in Emmerich ensures consistent supply and product conformity across the European market, backed by a broad range of precision tools and decades of distribution experience. Choosing a proven clamping rod contributes to a safer, more efficient shopfloor.
