Take advantage of a robust extension that combines a secure M16 thread, a substantial 170 mm overall length and a 32 mm shaft for stable, extended machining operations — order the VT520TM extension directly via Metav Werkzeuge or consult our technical team for compatibility advice.

Extension for screw-in cutters VT520TM — Teknik Cutting Tools, M16 thread, 170 mm overall length

A VT520TM extension for screw-in cutters engineered to extend cutter reach while preserving rigidity for milling and finishing tasks in industrial and workshop environments.

• M16 thread for secure mounting
• 170 mm overall length for extended reach
• 32 mm shaft diameter for high stiffness
• Robust 1.26 kg construction for stability

Greater reach without compromising rigidity

Extending the toolholder length enables access to deeper or recessed workpieces; the VT520TM achieves this with a 170 mm overall length that increases reach while an oversized 32 mm shaft diameter maintains lateral stability. The combination of reach and stiffness reduces deflection during heavy cuts, which in turn improves dimensional consistency and prolongs cutter life. For workshops where space is limited or parts feature deep bores, this extension keeps the cutting geometry predictable and repeatable.

Secure connection and reliable compatibility

A precise M16 thread and a dedicated opening diameter of 28.7 mm for thread-in cutters ensure a firm mechanical union between extension and cutter. The 40 mm taper/cone length stabilises the seating geometry, reducing micro-movements that can generate chatter. This mechanical certainty supports higher feed rates and consistent surface finish, translating raw specifications into measurable productivity gains on the shop floor.

Practical handling and workshop benefits

Weighing 1.26 kg, the extension balances inertial mass for steady cutting without becoming unwieldy during tool changes. The solid construction supports robust clamping and repeatable repositioning, which speeds set-up and reduces rework. When combined with standard thread-in cutters, the extension brings productive versatility to milling cells and toolrooms, making it suitable for both prototyping runs and serial production where controlled extension is required.
