Extension for Screw‑in Cutters VT501TM – M8 threaded arbor, 150 mm overall length (Teknik Makina)

The Extension for Screw‑in Cutters is a threaded arbor extension designed to increase reach for screw‑in milling cutters in workshop and CNC environments.

• M8 thread for secure connection
• 150 mm overall length for extended reach
• 15 mm shank for standard toolholders
• Low weight 0.202 kg for balanced handling

Extended reach while maintaining rigidity

The arbor extension provides an additional 150 mm of overall length without compromising on rigidity. With a 15 mm shank, the extension is compatible with many common toolholders, enabling longer overhangs where access is restricted. This reduces the need for special long‑reach cutters and simplifies setups, allowing precise machining in deep or awkward positions while maintaining acceptable run‑out and stability for milling operations.

Threaded seating for repeatable accuracy

A secure M8 threaded connection and a 30 mm taper seating ensure a repeatable mechanical interface between the extension and screw‑in cutters. The tapered seating promotes concentric clamping and reduces micro‑movement under load, which translates into consistent tool performance and predictable surface finish. For users unfamiliar with tapered fittings: the cone creates a tight mechanical contact that centres the cutter and resists loosening during rotation.

Balanced handling and quick integration

Weighing 0.202 kg, the extension remains light enough to avoid excessive imbalance on high‑speed spindles while providing meaningful reach. Its geometry supports straightforward integration into existing tooling systems: the larger shank diameter offers mechanical stiffness, and the reduced mass compared with longer adaptors helps to limit spindle strain. Compatibility with standard holders reduces changeover time and simplifies stock management in mixed production environments.

Practical productivity gains for workshops

By using this threaded arbor extension, setups become more versatile: one arbor can serve multiple screw‑in cutters, cutting down on the number of specialised tools required. The result is fewer tool changes, reduced inventory complexity and faster turnaround on small to medium production runs. Combined with Metav Werkzeuge’s reliable supply chain and technical support from the Emmerich hub, this extension supports continuous workshop operation and gives buyers confidence in consistent product quality.

FAQ

Is this extension compatible with standard screw‑in milling cutters? Yes. The Extension for screw‑in cutters (VT501TM) uses an M8 threaded connection and a 12.7 mm cutter opening diameter compatible with common screw‑in milling cutters from typical suppliers.

How does the tapered seating affect accuracy? The 30 mm taper seating centres the cutter and increases clamping stability; this design improves concentricity and helps maintain consistent run‑out during milling.

Will the weight impact spindle balance at high speeds? At 0.202 kg the extension is intentionally light to minimise imbalance; however, users should always check total assembly balance for very high spindle speeds and perform dynamic balancing if required.

Can this arbor extension reduce the need for long‑reach cutters? Yes. By extending reach by 150 mm while keeping a rigid 15 mm shank, the extension allows standard cutters to access deeper features, reducing the necessity for a larger set of specialised long‑reach tools.
