Extension for screw-in cutters VT505TM — 150 mm reach, M8 thread (Teknik Cutting Tools)

A compact tool extension, the Extension for screw-in cutters VT505TM increases reach for threaded milling cutters in CNC and manual machines while maintaining secure clamping and low additional spindle load.

• 150 mm overall length for increased reach
• M8 thread for standard screw-in cutters
• 16 mm shaft for robust tool clamping
• Lightweight: 0.23 kg reduces spindle load

Secure connections and extended working range for improved cycle flow

The extension is engineered to provide a reliable threaded connection and added reach without compromising stability. With a M8 screw interface and a full 150 mm overall length, the device is intended to extend the effective working distance of screw-in milling cutters while preserving concentricity. This reduces the need for repositioning or specialised long-reach cutters and supports smoother production sequences in batch and single-part operations. The combination of defined thread geometry and controlled dimensions translates into predictable behaviour under cutting loads.

Compatibility clarified: what the dimensions mean for tool choice

Compatibility is straightforward: the extension accepts screw-in cutters designed for a 14 mm opening and a cone length of 30 mm, and is mounted on a 16 mm shaft for standardised clamping. For workshops unfamiliar with these terms, the opening diameter refers to the receptacle on the cutter body, while the cone length describes the tapered engagement region that ensures axial and radial location. By matching these dimensions, the extension allows existing screw-in milling cutters to be used at increased reach without modifying cutter geometry or machine interfaces.

Lower spindle stress and consistent clamping for reliable finishing

Weighing just 0.23 kg, the accessory adds minimal rotating mass, which helps to keep spindle loads and dynamic imbalance low during operation. The 16 mm shaft diameter supports robust clamping, reducing runout risk compared with slender adapters. In practice this improves surface finish stability and reduces the frequency of rework caused by vibration-induced tool deviation. The result is a dependable extension that supports consistent part quality and efficient machine uptime.

Practical supply and service considerations for workshop integration

Sourced from Teknik Cutting Tools and distributed through Metav, the extension fits into a pragmatic supply chain designed for industry use. Metav’s inventory approach and product range support quick replacement and centralised procurement, which simplifies stock management for workshops and small manufacturers.

FAQ

What types of cutters fit this extension?
The extension is designed for screw-in milling cutters with a 14 mm opening and a 30 mm cone engagement; these dimensions ensure correct seating and secure clamping.

Is the VT505TM suitable for CNC and manual milling machines?
Yes, the VT505TM extension from Teknik Cutting Tools is intended for both CNC and manual setups where increased reach is required while maintaining a robust 16 mm shaft clamping.

How does the weight influence spindle performance?
At 0.23 kg the accessory adds minimal rotating mass; this helps to keep spindle load and dynamic imbalance low compared with heavier extensions.

Can this extension be used with any M8-threaded cutter?
The M8 thread provides a standardised connection, but correct fitment also depends on the cutter’s 14 mm opening and 30 mm cone length; matching all three dimensions is recommended.
