Extension for screw-in milling cutters VT515TM — M12 thread, 150 mm overall length (Teknik Cutting Tools)

Extension for screw-in milling cutters VT515TM is a dedicated toolholder designed to increase reach for screw-in milling operations while maintaining concentricity and clamping stability in production environments

• M12 thread for secure cutter attachment
• 150 mm overall length for extended reach
• 25 mm shank diameter for rigid clamping
• Weighs 0.542 kg for balanced handling

Gain extended reach without compromising engagement

The extension provides a 150 mm overall length that allows deeper access to workpieces or additional clearance for fixturing, while the M12 thread and a 40 mm cone engagement ensure the cutter is positively located. The internal opening of 20.7 mm matches standard screw‑in cutter shanks, reducing adaptor stacks and preserving axial alignment. This construction minimises wobble and contributes to reliable repeatability in serial production, which in turn reduces scrap rates and set‑up iterations.

Improve rigidity and surface quality with a stout shank

A 25 mm shank diameter gives the assembly the necessary stiffness for moderate cutting loads, improving surface finish and extending cutter life through reduced vibration. The extension’s mass (approx. 0.542 kg) is optimised to balance inertia and dynamic stability, so toolpaths remain predictable at typical feed rates used in milling centres. For machine shops seeking consistent results, this means fewer corrective passes and a more efficient machining cycle.

Integration and shopfloor benefits for production use

Designed for compatibility with screw‑in milling cutters, the component simplifies tooling inventories by enabling existing cutters to reach otherwise inaccessible features. The straightforward mechanical interface shortens changeover time and supports standardised maintenance checks. In practice, the extension is suited to CNC machining centres and toolrooms where extended reach, secure attachment, and dimensional reliability contribute directly to throughput and process stability.

FAQ

Which cutter shank sizes fit this extension?
The extension accepts screw‑in milling cutters with a shank opening of 20.7 mm; the M12 threaded interface gives secure axial engagement for standard screw‑in cutters (Teknik Cutting Tools VT515TM).

Is the component suitable for use in CNC machining centres?
Yes — the 25 mm shank and robust design make the extension appropriate for CNC applications where added reach and rigidity are required.

How much extra reach does the extension provide?
The overall length of 150 mm increases access compared with standard holders, allowing machining of deeper pockets or improved clearance for fixtures.

What ensures the cutter is securely retained?
Retention is delivered through the M12 thread combined with a 40 mm cone engagement, which together ensure positive location and repeatable concentricity for the cutter.

Can this extension affect surface finish or tool life?
By increasing stiffness through the 25 mm shank and limiting play at the connection, the extension supports improved surface finish and can reduce premature cutter wear under comparable cutting conditions.
