Take advantage of the combination of secure torque control, compact size and straightforward interchangeability to reduce tap breakage and downtime in production. Benefit from a quick-change solution that transmits torque via a robust 11 mm shaft square and is designed for taps to DIN 374/376 M18 — order through Metav Werkzeuge or request guidance from our consultants.

Quick-change insert SES 14mm x 11mm, Size 2 – with adjustable safety coupling (TECWERK)

The Quick-change insert SES 14mm x 11mm, Size 2 is a replaceable insert for tap holders and hand taps made to fit DIN 374/376 M18, featuring an adjustable safety coupling that limits torque to avoid tap breakage.

• Adjustable safety coupling for torque limitation
• Minimises tap breakage during threading
• Torque transmission via 11 mm shaft square
• Compatible with DIN 374/376 M18 taps

Safe threading through controlled torque

The insert is centred on an adjustable safety coupling that performs torque limitation to protect taps during interrupted cuts or misalignment. By limiting peak torque, the device prevents sudden overloading and therefore significantly reduces the risk of tap breakage, which in turn lowers scrap rates and maintenance interventions. This engineered protection is particularly valuable in repetitive production environments where tool failure causes costly stoppages.

Reliable fit and efficient torque transfer

Designed for precision engagement, the unit transmits drive forces over an 11 mm shaft square, ensuring direct and wear-resistant torque transfer to the tap. Compatibility with DIN 374/376 M18 means straightforward integration into existing tap holders and hand-tapping fixtures. The compact footprint and carefully specified interface dimensions contribute to consistent centring and repeatable thread quality across runs, improving process stability and reducing rework.

Fast changeover and application flexibility

The quick-change concept allows fast replacement of worn or differently sized inserts so that different shank measurements can be accommodated by swapping the unit. The insert’s construction supports efficient workshop workflows and lowers setup time for maintenance or batch changes. For specialised applications where shank variants are in use, matching the correct SES insert size maintains torque control and protects high-value taps — assistance for selection is available from Metav Werkzeuge’s specialist team.

FAQ

What is the main purpose of the adjustable safety coupling?
The adjustable safety coupling in the Quick-change insert SES 14mm x 11mm, Size 2 limits peak torque to protect taps and reduce the likelihood of tap breakage during threading operations.

Which tap standards does this insert support?
The insert is designed for use with taps conforming to DIN 374/376 M18 and mates with compatible tap holders and hand-tapping fixtures.

How is torque transferred from the driver to the tap?
Torque is transmitted via the 11 mm shaft square, providing a direct and robust drive interface that minimises slippage and wear.

Are different shank sizes supported by the SES system?
Yes, the SES quick-change concept requires different inserts for varying shank measurements; swapping the insert adapts the system to the required shank size while maintaining torque control.

What dimensions should be checked for compatibility with existing holders?
Check the core dimensions such as diameter 14 mm, square drive 11 mm and the overall interface lengths (L1, L3, L4, L5) to ensure correct seating and centring in the tap holder.
