Extension for screw-in milling cutters — 100 mm, M10 thread (Teknik Makina)

The Extension for screw-in milling cutters is a threaded extension rod for use with thread-mounted milling cutters, designed to increase reach while retaining concentricity and stability in milling and CNC operations.

• M10 thread for secure cutter mounting
• 100 mm total length for extended reach
• 20 mm shaft diameter for stable clamping
• 17.7 mm cutter shank opening for compatibility

Precision where length is required without sacrificing rigidity

This extension delivers a measured increase in reach while minimising flex. The 100 mm total length is engineered to provide additional clearance in fixtures and deep cavities, yet the 20 mm shaft preserves lateral stiffness to reduce vibrations. The threaded interface with an M10 thread and a 30 mm cone seating ensures a firm mechanical connection; this reduces radial runout and supports repeatable positioning during serial machining. By selecting an extension with defined tolerances, shops can maintain part accuracy without resorting to ad‑hoc improvisation.

Straightforward integration with thread-mounted cutters

Designed for compatibility with screw-in style cutters, the extension features a 17.7 mm cutter shank opening and a 30 mm cone length for reliable seating of the cutter body. The geometry supports standard thread-mounted tooling systems commonly found in milling spindles and toolholders. Installation is a simple mechanical step: the extension is secured by the M10 thread into the cutter or holder and checked for concentricity before operation. This predictable assembly reduces setup time and helps teams keep production running smoothly.

Built for dependable workshop use and supply continuity

Constructed for routine industrial use, the extension offers a robust, low-mass solution at 0.235 kg that minimises added inertia while providing the necessary reach. The compact weight helps preserve spindle dynamics compared with longer, heavier adapters. Supplied by Teknik Makina and available through Metav Werkzeuge, the component is part of a broader catalogue that supports centralised sourcing, helping workshops reduce supplier complexity and secure dependable replenishment for precision tooling.

FAQ

What is the main purpose of this extension?
The extension VT509TM by Teknik Makina increases reach for thread-mounted milling cutters, providing an additional 100 mm overall length while maintaining secure mounting via the M10 thread.

Which cutter shank sizes fit the extension?
The extension accepts cutter shanks up to the specified opening of 17.7 mm, allowing direct seating of compatible screw-in milling cutters.

How is the extension mounted and secured?
Mounting is via the M10 threaded interface; the 30 mm cone length provides seating for the cutter and ensures a firm mechanical connection once tightened.

Will using the extension affect spindle balance?
The extension weighs 0.235 kg, which is modest; however, balancing should be checked after installation if high-speed machining or precision balancing is required with the extended assembly.

What are the key dimensions to verify before use?
Verify the 100 mm total length, shaft diameter 20 mm, cutter opening 17.7 mm and the M10 thread to ensure compatibility with the intended cutter and toolholder.
