Quick-change insert SE 9 mm x 7 mm, Size 2 — for DIN 374/376 M12 (TECWERK)

The Quick-change insert SE 9 mm x 7 mm, Size 2 is a compact holding insert for taps conforming to DIN 374/376 M12, engineered for fast tool changes in workshop and production environments.

• Quick-change insert for tap holding
• Torque via 7 mm square shank
• Compatible with DIN 374/376 M12 taps
• Compact dimensions for tight setups

Faster set-ups and uninterrupted production flow

The quick-change design significantly reduces downtime during tap changes by allowing taps to be held securely by the integrated quick-clamping mechanism. This means changeovers are completed more quickly than with traditional fixed holders, supporting higher productivity on the shop floor. The insert is particularly suited to environments where frequent tool exchanges are required, enabling a smoother workflow and less machine idle time.

Reliable torque transmission and clear mechanical behaviour

Torque is transmitted through the 7 mm square shank, providing a direct and measurable path for power transfer between toolholder and machine spindle. The insert is supplied without a safety coupling, so torque behaviour is deterministic and suited to controlled production settings where overload protection is handled elsewhere in the process. Key length and diameter references are designed to integrate with standard tap geometries, ensuring consistent thread formation when used with DIN 374/376 M12 taps.

Compact geometry that simplifies fixture planning

With concise overall dimensions and a compact profile, the insert reduces interference in confined fixtures and multi-tool arrangements. The measured values for critical interfaces support reliable clamping: short engagement and accessible clearances make it simpler to position the tool accurately in tight nests. For workshops aiming to save space without compromising process stability, the compact form factor supports denser tool layouts and easier maintenance access.

Practical compatibility and selection guidance

Different shank sizes require corresponding inserts, so the insert is intended to be combined with matched holders depending on the shank standard in use. The design holds taps via the quick-clamping device, which stabilises the thread tap during operation and delivers repeatable results across batches. For mixed tooling fleets, keeping a small stock of matched inserts reduces set-up complexity and prevents downtime caused by incompatible interfaces.

FAQ

Is this insert compatible with DIN 374/376 M12 taps?
Yes. The quick-change insert SE 9 mm x 7 mm, Size 2 is designed specifically for use with taps to DIN 374/376 M12 and matches the relevant tap interface dimensions.

How is torque transmitted through the insert?
Torque is transmitted via the 7 mm square shank, providing a direct mechanical link between holder and spindle; this design ensures predictable torque transfer during tapping operations.

Does the insert include a safety coupling?
No. The insert is supplied without a safety coupling; overload protection must be provided elsewhere in the toolchain or machine control system.

Are other shank sizes supported with the same insert?
Different shank sizes require corresponding inserts. This particular insert uses a 7 mm square shank; for alternate shank dimensions, the matching insert must be selected.

What are the key dimensions for fixture planning?
Relevant interface dimensions are: diameter 9 mm, square shank 7 mm, L1: 32 mm, L3: 5 mm, L4: 35 mm, L5: 11 mm, D: 48 mm and D1: 31 mm.
