Take advantage of a tool that combines axial compensation and an integrated coolant feed to maintain thread quality and reduce scrap during synchronised tapping; the unit’s high runout accuracy and strong clamping capability support reliable production cycles — order the TECWERK synchronised tapping chuck through Metav Werkzeuge or consult the Metav team for application advice.

TECWERK Synchronised Thread‑cutting Chuck (DIN 69871 AD/B, SK40) with coolant feed and axial compensation

The TECWERK synchronised thread‑cutting chuck is a precision clamping unit for CNC machines with synchronised tapping spindles, designed to handle metric threads in the M3–M12 range while compensating for minor pitch or synchronisation discrepancies.

• Synchronised tapping for M3–M12 threads
• Axial compensation ±0.5 mm for sync errors
• Integrated coolant feed for through‑tool cooling
• High runout accuracy and strong clamping force

Precision tapping that reduces scrap and cycle variability

The chuck delivers repeatable thread quality by combining a precisely machined clamping interface with axial compensation capable of absorbing synchronisation deviations of ±0.5 mm. This mechanical compensation means fewer broken taps and reduced rework in short‑cycle CNC tapping operations, particularly where minor spindle synchronisation drift occurs. The specification to DIN 69871 and the compact ER16 interface ensure the unit fits standard synchronised tapping spindles, translating technical conformity into operational reliability on the shop floor.

Built‑in coolant routing for improved tool life and finish

An integrated coolant feed supplies lubricant and cooling directly to the cutting zone, supporting longer tool life and superior surface finish when cutting internal threads from M3 to M12. For materials and operations where heat and chip evacuation are critical, through‑tool coolant reduces thermal expansion and chip packing, thereby preserving thread geometry and sustaining consistent torque profiles. The combination of coolant delivery with high runout accuracy contributes directly to process stability and predictable maintenance intervals.

Compatibility, clamping force and application scope

Engineered for CNC machines equipped for synchronised tapping, the unit mates to standard spindle interfaces conforming to DIN 69871 AD/B and uses an ER16‑GB connection for the tap collet. The compact 22 mm outer diameter and 79 mm length (A) keep the tool assembly compact while maintaining high clamping force through the tensioned tap collet with integrated square, enabling secure retention of taps for both right‑ and left‑hand threads. This construction is particularly suitable for small to medium thread series where fast indexing and consistent torque transfer are required.

Practical sourcing and supply reliability for production use

Metav’s procurement and distribution model ensures that devices like this synchronised tapping chuck are available with transparent logistics from Emmerich, backed by decades of experience in precision tooling. Combining verified technical data with stable stock handling reduces lead‑time uncertainty and supports uninterrupted production planning. For complex installations or to confirm machine compatibility, technical clarification is available from Metav Werkzeuge to ensure the chuck integrates smoothly into existing tapping cells.
