TECWERK synchronous tapping chuck SK40 (M3–M27, 95 mm)

The synchronous tapping chuck is a CNC-ready thread-cutting holder designed to compensate pitch differences between the tap and the synchronised spindle while supplying coolant and ensuring high clamping force.

• Synchronous tapping for M3–M27 threads
• Axial compensation ±0.5 mm for pitch mismatch
• Integrated coolant feed for continuous operation
• High runout accuracy with ER32-GB taper

Precision and machine compatibility for secure tapping

The chuck conforms to DIN 69871 AD/B and is supplied in an SK40 shank with an ER32-GB tool interface, making it suitable for standard CNC tapping spindles and toolholders. The compact A = 95 mm length and D = 50 mm outer diameter allow integration into dense toolpacks, while the specified thread range M3–M27 covers small to medium-sized metric threads. These parameters ensure predictable machine set-up and straightforward replacement in production cells, supporting consistent cycle times and predictable throughput.

Axial compensation that protects thread quality and tooling

Equipped with a mechanical axial compensation mechanism that provides - / + 0.5 mm travel, the chuck absorbs minor synchronisation deviations between the tap and the spindle. This feature corrects for push and pull errors, reducing the risk of thread distortion and premature tap breakage. The compensating action translates into fewer scrap parts and extended tool life, which in turn improves overall process reliability and reduces unplanned downtime in high-volume or mixed-batch environments.

Built for production: coolant, clamping and bidirectional threads

The design includes an integrated coolant feed to the cutting zone and a tap-collet arrangement that provides high clamping force via a collet with an integrated square, preventing tool slip during heavy cutting or interrupted threads. The chuck accepts both right‑ and left‑hand threads, allowing flexible deployment across tooling sets. High runout accuracy minimises wobble and ensures concentric tapping, which is essential for maintaining thread tolerance and surface finish in precision assemblies.

Practical advantages and support for workshop integration

As a production component, the chuck reduces manual interventions by compensating synchronization errors and delivering coolant directly to the cutting edge, which both improves cycle stability and lowers the frequency of tool checks. For integrators and workshop managers, the combination of DIN-compliant form, compact dimensions and robust clamping behaviour simplifies spare-part logistics and standardises tapping operations across multiple CNC machines. Metav’s distribution and technical advisory services help to match the chuck to machine controllers and synchronised tapping units.

FAQ

How does axial compensation improve tapping reliability?
Axial compensation allows the chuck to absorb small differences in pitch or timing between the tap and the synchronised spindle; the TECWERK synchronous tapping chuck protects the cutting edge and reduces thread rejects by ±0.5 mm of travel.

Which machines is this chuck compatible with?
The chuck is intended for CNC machines equipped with a synchronised tapping spindle and an SK40 toolholder; its ER32-GB interface supports common collet systems for tapping operations.

Can the chuck handle both right‑ and left‑hand tapping?
Yes. The design supports both right‑ and left‑hand threads, enabling flexible use across components and reversing operations without tool changes.

What benefits does the integrated coolant feed provide?
Direct coolant delivery to the tool improves chip evacuation and cooling, which extends tap life and maintains thread surface quality under continuous production conditions when using the TECWERK tapping chuck.

Is the chuck suitable for small-diameter threads?
The chuck covers a thread range from M3 to M27, making it appropriate for small to medium metric threads commonly required in mechanical and assembly work.
