Quick-change insert SE 12 mm × 9 mm, Size 2 for DIN 374/376 M16 (TECWERK)

The Quick-change insert SE 12 mm × 9 mm, Size 2 is a dedicated holder for tapping applications to DIN 374/376 M16, designed for rapid tool exchange in production and workshop environments

• Rapid tool changes with quick-change design
• Torque transmission via 9 mm square shank
• Compatible with DIN 374/376 M16 threading tools
• Clear dimensional data for process planning

Efficient threading operations through fast changeovers

The quick-change insert is engineered to reduce non-productive time by enabling fast replacement of threaded tools. With a defined 12 mm diameter interface and a 9 mm square shank, the insert provides stable seating for taps held by the quick-clamping mechanism. This results in shorter set-up times and higher machine utilisation, making it suitable for repetitive threading tasks in small-batch production as well as larger runs.

Secure torque transmission for consistent thread quality

Because the torque transmission is effected via the shaft square, the load is transferred positively and predictably to the tap. The design operates without a safety coupling, so torque is transmitted directly through the square shank; this ensures repeatable torque behaviour and consistent thread form when used with compatible tapping tools to DIN 374/376 M16. Users benefit from precise power transfer that supports reproducible quality in each cycle.

Clear dimensions and measurable specification for process planning

Detailed dimensional values support integration into tool lists and CAD fixtures. Key lengths and diameters are provided to facilitate fixture design, collision checks and inventory management. The compact footprint and the standardised interface simplify spare-part planning and make this insert straightforward to specify alongside existing toolholders and machine setups in workshops and production cells.

Designed for workshop compatibility and flexible shank options

The insert requires matching shank sizes for different toolholder variants, enabling a modular approach to tap holding. The construction allows taps to be retained by the quick-clamping device, while the square shank provides the positive drive. This modularity supports mixed tooling strategies and reduces the number of complete holders required, improving capital efficiency for maintenance and toolroom planning.

FAQ

What tap standards is the insert compatible with?
The quick-change insert is designed for tapping tools conforming to DIN 374/376 M16 and provides the standard interface for secure clamping and drive.

How is torque transmitted to the tap?
Torque is transmitted via the 9 mm square shank; the design transfers drive positively without a safety coupling for repeatable torque behaviour.

Can the insert be used with different shank sizes?
Different inserts are required for different shank sizes; the product supports a modular approach where matched inserts are selected for the corresponding shank.

Which dimensions are critical for fixture integration?
Key dimensions such as L1, L3, L4, D and D1 are provided to assist with fixture planning and collision checks when integrating the insert into a toolholding system.

Is a safety coupling included with this insert?
No, this insert is supplied without a safety coupling; torque is delivered directly through the square shank, which should be considered in process risk assessments.
