TECWERK Quick-change insert SE 9 mm x 7 mm, Size 1 — for DIN 374/376 M12

The TECWERK Quick-change insert SE 9 mm x 7 mm (Size 1) is a compact tool-holding solution designed for secure retention of thread taps in quick-clamping systems used for DIN 374/376 M12 tapping operations.

• Quick-change design for fast tool swaps
• Square shank torque transmission 7 mm
• Compatible with DIN 374/376 M12 taps
• Compact Size 1 with precise dimensions

Reduce machine downtime with fast, repeatable tool changes

The quick-change insert is engineered to allow rapid replacement of taps where a quick-clamping device is used, so setup time is minimised and production flow is maintained. By using a standardised insert format with a defined 9 mm engagement and a 7 mm square shank for drive, exchange procedures are simplified and the time spent on changeovers is reduced. The design is oriented towards workshop efficiency and is compatible with established tap-holding systems, where the insert is clamped and the tap is held securely by the quick-clamping mechanism.

Secure torque transfer through the square shank for reliable tapping

Torque is transferred via the 7 mm square shank, which provides positive drive and reduces slippage compared with round-shaft solutions; this ensures consistent thread quality and repeatability. The insert is supplied without safety coupling, intended for assemblies where the clamping system provides the necessary protection; the torque path is therefore direct and mechanically robust. For users integrating the insert into existing tool posts or holders, the direct square-shank transmission facilitates straightforward compatibility checks and predictable torque behaviour under load.

Precise dimensions for predictable fit and alignment

Compact Size 1 geometry offers defined dimensions that aid in selecting the correct insert for a holder and for maintaining alignment in confined setups. Key measures include L1: 18.5 mm, L4: 21.5 mm and a head diameter of D: 30 mm, which combine to give a low-profile, stable interface between holder and tap. These dimensions are especially useful when planning tool layouts for multi-spindle machines or crowded tool turrets, because the predictable envelope simplifies interference checks and fixture design without sacrificing access to the workpiece.

Practical integration notes for production environments

Inserts of this type are intended for applications where thread taps are retained by a quick-clamping device; different shank sizes require matching inserts, so consistency across a tool set is recommended to avoid mismatches. The compact construction supports dense tool arrangements and is suitable for both one-off setups and serial production where frequent tool changes are expected. Documentation and measured dimensions support planning and spare-part provisioning, ensuring that changeovers remain quick and error-free.

FAQ

How is the thread tap held when using this insert?
The insert works with a quick-clamping device that retains the thread tap while the insert provides the interface and drive via the 7 mm square shank.

Is this insert compatible with DIN 374/376 M12 taps?
Yes, the TECWERK Quick-change insert SE 9 mm x 7 mm (Size 1) is specified for use with DIN 374/376 M12 tapping applications.

What are the key dimensions to check when fitting the insert into a holder?
Check the shank square 7 mm, overall engagement 9 mm, and the axial dimensions such as L1: 18.5 mm and L4: 21.5 mm to ensure correct fit and clearance.

Can the insert be used where a safety coupling is required?
This item is supplied without a safety coupling; compatibility with safety devices depends on the holder and machine configuration rather than the insert itself.

What is the SKU for ordering and identification?
The SKU for this quick-change insert is 4000832639NW for reference when sourcing or requesting spares.
