VDR-NT40I-S drawbar – 545 mm, 5/8-11UNF (Vertex)

A precision drawbar designed to secure NT40 tool holders in CNC spindles, offering standard-thread retention and straightforward installation for workshop use

• 545 mm overall length
• 5/8-11UNF threaded connection
• Compatible with NT40 tool holders
• Robust 1 kg construction

Consistent clamping for predictable machining results

The VDR-NT40I-S drawbar provides a mechanically simple yet effective method of retaining tool holders in a spindle, translating into stable axial retention during machining. By using a standard 5/8-11UNF thread, the component interfaces with widely used retention knobs and clamping systems, reducing the need for bespoke adapters. This compatibility supports a streamlined workflow and reduces machine downtime because replacement or interchange is rapid and unambiguous. The overall length of 545 mm ensures sufficient engagement depth for many NT40 configurations, while the modest weight of 1 kg aids safe handling during tool changes without compromising robustness.

Standard interfaces and practical workshop benefits

Designed for practical integration into existing setups, the drawbar’s NT40 alignment and standard thread make it suitable for many common CNC toolholding environments. The reliance on established interfaces simplifies inventory management and spares provisioning, which is especially relevant for production settings that value repeatability and quick turnarounds. Fewer special parts mean fewer procurement steps and lower logistical complexity. The straightforward mechanical design also reduces maintenance demands; inspections focus on thread condition and straightness, which are easy to monitor without specialised equipment.

Built for everyday use with an emphasis on reliability

Constructed for routine workshop handling, the component prioritises durability and dependable performance over unnecessary complexity. The combination of a compact mass and a long engagement length balances ease of handling with secure clamping, supporting consistent tool repeatability across shifts. Supplied by the Vertex line, the part benefits from manufacturer recognition in machining accessories, helping to ensure consistent quality control. For procurement and integration, the clear technical specification minimises guesswork and supports concise documentation in maintenance schedules and parts lists.
