Extension for screw-in cutter VT504TM — Teknik Makina, 150 mm, M8 thread

Extension for screw-in cutter VT504TM delivers a compact solution for extending the reach of screw-in milling cutters in constrained setups and deeper machining operations.

*150 mm overall length
*M8 threaded interface for secure attachment
*16 mm shank for standard toolholders
*Lightweight design at 0.234 kg

Extended reach with industrial-grade stability

The VT504TM extension provides a reliable method to increase working depth while maintaining machining stability. With an overall length of 150 mm, the component allows access to recessed features and deeper pockets without the need for improvised extensions that increase runout. The M8 thread forms a positive, repeatable mechanical connection to compatible screw-in cutters; this threaded coupling reduces axial play and supports consistent tool positioning. For production or maintenance environments where tool repeatability is essential, this extension balances reach with functional rigidity to support accurate machining outcomes.

Secure connection and controlled concentricity

Designed for compatibility with screw-in milling cutters, the extension features a 16 mm shank and a screw-in opening sized at 14 mm, matched to a 30 mm cone length for the cutter interface. The combination of 16 mm shank geometry and a precision-threaded M8 interface promotes stable clamping in common collet or chuck setups. By keeping shank runout low and the clamped length sufficient, the accessory helps to preserve cutting-edge life and surface finish. The product’s geometry is explained here in plain terms: the cone length ensures the cutter seats fully in the extension, the shank diameter suits standard holders, and the thread locks the assembly for repeatable performance.

Low mass for improved handling and dynamic behaviour

At just 0.234 kg, this extension is lightweight yet purpose built for workshop use. Reduced mass at the tool end lowers centrifugal forces during rotation and simplifies dynamic balancing when high spindle speeds are required. For machinists, this translates into easier tool changes, reduced spindle load, and a lower tendency for chatter in many common applications. The modest weight also supports manual handling during set-up and maintenance, while still providing sufficient material to withstand regular workshop use.

Practical compatibility and straightforward installation

The unit has been specified to fit into standard machining workflows: an M8 threaded interface for the cutter, a 14 mm screw-in opening to accept the cutter root, and a 16 mm shank to suit common holders. Installation is mechanical and direct — the cutter is screwed into the extension and the shank is secured in the toolholder — eliminating the need for adaptors or special fixtures. For complex assemblies or unusual machine interfaces, Metav’s documentation and product experts are available to clarify fitment options and to recommend appropriate clamping practices to preserve accuracy and safety.

FAQ

Which cutters are compatible with this extension?
The VT504TM extension for screw‑in cutter by Teknik Makina is compatible with screw-in milling cutters that match an M8 threaded connection and a 14 mm root diameter; check cutter specifications against these dimensions.

How does the M8 thread affect setup security?
An M8 threaded interface on the VT504TM creates a positive mechanical connection between extension and cutter, improving axial stability and repeatability during repeated mounting and demounting.

Can the extension be used for deep pocket machining?
Yes, the 150 mm overall length enables deeper reach for recessed machining tasks while the design aims to maintain clamping stability for consistent cutting performance.

Will the 0.234 kg weight influence spindle dynamics?
The lightweight construction of 0.234 kg reduces tool end inertia and generally aids dynamic behaviour at higher spindle speeds, while still offering sufficient mass for stable handling.

What holder dimensions are required for the shank?
The shank diameter is 16 mm; the extension is intended for holders or collets that accept a 16 mm shank and secure it with the usual clamping methods.
