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

Extension for screw-in cutters for use with screw-in indexable insert cutters, designed to extend working reach while maintaining concentricity and simple mounting

• 150 mm overall length for deeper reach
• M8 thread for secure screw-in connection
• 15 mm solid shaft for rigid support
• 12.7 mm opening for standard insert cutters

Longer reach with predictable, machine-friendly performance

The extension arbor provides a controlled increase in working distance without sacrificing precision. With an overall length of 150 mm, the unit is engineered to reduce the need for complex fixturing when machining recessed features or tooling fixtures. The solid 15 mm shaft offers stable support, which helps to reduce unwanted vibration and runout during operations, and the relatively low mass of 0.208 kg minimises additional spindle load. For workshop planners and production engineers, this means predictable machining cycles and fewer interruptions caused by tool instability.

Secure mounting that keeps repeatability high

Threaded connection via the M8 thread ensures a positive mechanical joint to the cutter body and contributes to consistent concentricity across repeated installations. The internal opening of 12.7 mm suits many screw-in indexable cutters and supports straightforward assembly with standard fastening hardware. The 30 mm cone length creates a reliable seating surface for the cutter, translating to repeatable radial and axial positioning. The result is an extension that preserves the original tool geometry and repeatability, reducing scrap rates and setup time.

Simple integration into existing tooling systems

Designed for practical compatibility, the extension fits into common tool setups for indexable cutters and is particularly useful where increased reach is required without converting to long overhang cutters. The component’s straightforward geometry permits quick verification of fit and alignment on the bench; the absence of complex adapters means fewer parts to manage in inventory. This practical design supports leaner tool management and faster changeovers in small-batch or mixed-production environments.

Durable, production-oriented specification

Although detailed material specifications are not supplied in the product data, the component’s dimensions and thread standardisation reflect a production-orientated mindset: standardised thread (M8), defined seating cone length (30 mm) and a measured shaft diameter (15 mm). These measurable parameters allow engineering teams to assess stiffness and dynamic behaviour in context with machine and cutter characteristics. Where higher rigidity or specific coatings are required, the extension can be evaluated alongside suitable cutter bodies to ensure compatibility with the intended machining task.

FAQ

Which cutter types are compatible with this extension?
The extension for screw-in cutters (VT500TM) is intended for screw-in indexable insert cutters; compatibility is determined by the cutter’s 12.7 mm mounting opening and M8 screw connection.

How does the M8 thread affect mounting stability?
The M8 thread used on the Technik Makina extension (VT500TM) provides a secure mechanical connection that contributes to repeatable seating and reduced axial movement during machining.

What are the key dimensions to check before fitting?
Confirm the cutter’s mounting opening (12.7 mm), the machine-side holder clearance for a 150 mm overhang, and the 15 mm shaft diameter to ensure correct fit and stiffness with the selected cutter body.

Will the extension significantly increase spindle load?
With a weight of 0.208 kg, the extension adds minimal mass; assessment should still be made in context with the spindle speed and cutter mass to maintain dynamic stability during operation.

Can the extension be used with different brands of indexable cutters?
The extension (VT500TM) is compatible with cutters that match the listed mounting dimensions and an M8 thread; cross-brand fit should be verified by checking the cutter’s mounting geometry.
