9mm Quick-Change Insert SES 7mm Square Shank for DIN 374/376 M12, Torque-Limited Safety Clutch - TECWERK

Take advantage of the combination of controlled torque protection and quick-change convenience to reduce tap breakage and increase uptime in the workshop; order the part through Metav Werkzeuge or contact their advisers for application support and matching to other shank sizes.

Quick-change insert SES 9 mm x 7 mm Size 2 – TECWERK

The Quick-change insert SES 9 mm x 7 mm Size 2 is a compact exchange insert for M12 tapping applications, designed to limit torque and protect taps in production and repair environments.

• Adjustable safety clutch for torque limitation
• Reduces risk of tap breakage during threading
• Torque transmitted via 7 mm square shank
• Compatible with DIN 374/376 M12 tapping tools

Minimise tap breakage with controlled torque transfer

The core advantage of this insert is the adjustable safety clutch, which provides torque limitation to protect thread-cutting tools during interrupted or demanding operations. By disengaging at a preset torque, the mechanism reduces the likelihood of tap breakage, lowering scrap rates and maintenance time. For workshops that run mixed batches or repair tasks, this protective function improves process reliability and reduces the frequency of tool changeovers.

Fast exchange and reliable drive connection for production speed

Designed as a quick-change insert, the component enables rapid replacement of worn or different-size inserts without complex retooling, preserving machine uptime. The torque transmission via the 7 mm square shank ensures a positive mechanical drive connection that resists slippage under load. Compatibility with DIN 374/376 M12 tapping tools makes it straightforward to integrate into existing tapping holders; different shank sizes require the corresponding insert types to maintain correct fit and torque transfer.

Defined dimensions for predictable engagement and fit

Key dimensions are provided for precise planning and fixture adjustments: L1: 32 mm, L3: 30.5 mm, L4: 35 mm, L5: 34 mm, D: 50 mm, D1: 31 mm, with a nominal tool diameter of 9 mm and a 7 mm square drive. These measurements inform how the insert engages with the tapping holder and determine achievable thread depth and clamping clearance. Clear dimensional data supports jig design and helps avoid interference during automated or manual tapping cycles.

Built for workshop reliability and straightforward inventorying

The unit is supplied as a single-piece pack and suits repair shops and production lines where predictable torque behaviour and quick serviceability matter. The integrated safety clutch not only protects tools but also contributes to consistent process outputs, which is especially valuable when threading on harder or variable materials. For operations seeking to standardise tooling, the SES quick-change format simplifies stockkeeping while maintaining the flexibility to match different shank standards.

FAQ

What thread sizes is this insert designed for?
The SES quick-change insert is specified for use with DIN 374/376 M12 tapping tools and is matched to that standard for reliable engagement.

How does the adjustable safety clutch protect taps?
The adjustable safety clutch limits torque transmission once the set threshold is reached, which in the SES insert prevents sudden overloads that can cause tap breakage.

Is the 7 mm square drive the only available shank size?
This particular insert features a 7 mm square drive; other shank sizes require the corresponding SES variants to ensure correct torque transfer and fit.

Can this insert be used in automated tapping heads?
Yes, the quick-change format and defined dimensions such as L1, L3 and D support integration into automated tapping setups, provided the holder accepts the SES geometry.

What is included in the delivery?
The product is supplied as a single unit (packaging unit 1) ready for fitting into the matching quick-change holder.
