Take advantage of a synchronised thread-cutting chuck that combines a Weldon shank to DIN 1835 B+E, integrated coolant feed and a length-compensation range of ±0.5 mm to keep cycle times predictable and scrap rates low; order directly via Metav Werkzeuge or contact our consultants for application advice.

TECWERK Synchronized Thread-Cutting Chuck DIN 1835 B+E — Weldon shank with coolant feed, for M4–M27

The TECWERK synchronized thread-cutting chuck is a precision accessory for synchronised thread cutting on CNC machines, designed to equalise pitch differences and maintain running accuracy in high-volume production.

• Weldon shank DIN 1835 B+E
• Integrated coolant feed
• Compensates synchronisation errors ±0.5 mm
• High runout accuracy and clamping force

Minimise rejects with controlled synchronisation and clear numerical benefits

The synchronised chuck delivers measurable improvements in thread quality by compensating for pitch discrepancies between the tap and the synchronised spindle. With ±0.5 mm length compensation, the device absorbs small variances that would otherwise transfer into bad threads or broken tools. The combination of Weldon shank DIN 1835 B+E and compact dimensions provides a stable connection to the machine, helping to reduce rework and increase first-pass yield. This technical stability directly improves process efficiency on automated thread-cutting cycles.

Reliable clamping and coolant management boost tool life and consistency

Equipped with an integrated coolant feed, the chuck supports effective chip evacuation and consistent lubrication at the cutting zone, which reduces tool wear and improves thread finish. The design achieves high clamping force through threaded tap collets with an integrated square, ensuring taps remain secure under both push and pull loads. The result is longer tool life, fewer changeovers and a steadier production rhythm — key advantages in any busy workshop or production cell.

Precision engineering that fits into CNC thread-cutting systems

The chuck is intended for use on CNC machines with synchronised thread-cutting devices and accepts both right- and left-hand threads across a broad range (M4–M27). The compact outer diameter of 50 mm and the 25 mm shank allow straightforward integration into existing tool systems while the overall length (A = 69 mm) keeps the tool projection optimised for stability. High runout accuracy supports consistent thread geometry, which is particularly relevant for serial production and critical-fit components.

Practical handling and application-oriented design for workshop use

Made for production environments, the chuck’s features focus on usability and robustness: the Weldon shank simplifies mounting, the coolant feed reduces manual intervention for lubrication and the compensation function dampens the effects of minor spindle synchronisation errors. These characteristics make the chuck suitable for machine shops and subcontractors who require reliable, repeatable thread-cutting performance without frequent adjustments.
