Quick-change insert SES 11 mm x 9 mm, Size 2 – adjustable safety coupling (TECWERK)

Quick-change insert SES 11 mm x 9 mm Size 2 provides a torque-limiting adapter for thread tapping applications, designed for use with DIN 374/376 M14 taps and workshop toolholders

• Adjustable safety coupling for torque limitation
• Prevents tap breakage during threading
• Compatible with DIN 374/376 M14 taps
• 9 mm square drive for positive torque transfer

Reduce tool breakage and maintain production flow

The adjustable safety coupling built into this quick-change insert limits torque transmission when resistance rises unexpectedly, significantly reducing the risk of tap breakage. As a result, thread production becomes more reliable and less prone to costly stoppages; the mechanism disengages before a tap sustains irreversible damage, protecting consumables and avoiding rework. This measurable reduction in scrap and downtime translates into better throughput and lower total operating cost per threaded component.

Precise torque control for consistent threads

Torque is transferred through the 9 mm square drive, ensuring a positive, backlash-free connection between driver and tap shank; the torque-limiting element is adjustable to suit the thread size and material conditions. Because the torque is controlled mechanically rather than electronically, the system reacts instantly to overloads and maintains thread quality across batches. The result is repeatable, consistent threads with fewer rejects and a predictable process window for production planners and workshop engineers.

Compact design that integrates with existing tooling

With a compact footprint (D 50 mm, D1 31 mm, L1 32 mm) and a nominal diameter of 11 mm, the insert fits into common toolholders while keeping the working envelope small. The torque is transmitted over the shaft square, so different shank dimensions require corresponding inserts; this modular approach lets maintenance teams replace only the worn insert instead of the entire driver assembly. The compact size and standard interface simplify storage and logistics in busy workshops.

Engineered for workshop practicality and safety

The unit is supplied as a single-piece package and is intended for quick replacement when wear occurs. The mechanical limiting principle provides a clear operational advantage: fast recovery after an overload without complex reset procedures. Documentation and simple adjustment make the insert suitable for both production environments and skilled maintenance teams that demand robust, service-friendly components from a recognised supplier.

FAQ

Which tap types are compatible with this quick-change insert?
The quick-change insert SES 11 mm x 9 mm Size 2 is compatible with taps to DIN 374/376 M14 and designed to interface with standard tap shanks using the 9 mm square drive.

How does the adjustable safety coupling work?
The adjustable safety coupling in the TECWERK SES insert mechanically limits torque transmission; when the set torque is exceeded, the coupling slips to prevent damage to the tap and driver.

Is a special driver required to use this insert?
No special driver is required beyond a matching toolholder that accepts the SES interface and the 9 mm square drive; different shank sizes call for the corresponding insert variant.

Can the torque setting be changed during operation?
Torque adjustment is performed using the coupling mechanism; settings should be adjusted when the tool is stationary and according to workshop safety procedures.

What dimensions should be checked before ordering?
Verify the square drive (9 mm), the overall diameter (11 mm) and the key envelope dimensions (D 50 mm, L1 32 mm) to ensure compatibility with existing holders and clearance conditions.
