22mm Quick-Change Insert SES Size 3 for DIN 374/376 M30, 18mm Square, Adjustable Torque Safety Clutch - TECWERK

Take advantage of the combination of an adjustable safety coupling, robust torque transmission via an 18 mm shaft square, and a compact design that reduces tap breakage and downtime; order the insert directly via Metav Werkzeuge or consult our specialists for matching inserts and shank sizes.

Quick-change insert SES 22 mm × 18 mm, Size 3 — TECWERK for DIN 374/376 M30 with adjustable safety coupling

The Quick-change insert SES 22 mm × 18 mm, Size 3 is a compact adapter designed for safe torque-limited threading operations with taps conforming to DIN 374/376 M30.

• Adjustable safety coupling for torque limitation
• Prevents thread tap breakage during operation
• Torque transmitted via 18 mm shaft square

Consistent torque control to protect tooling and processes

The adjustable safety coupling provides a precise torque limit mechanism so that the tap slips before catastrophic failure occurs. This torque-limiting function reduces tool replacement frequency and minimises unscheduled machine downtime, which translates into measurable savings in cycle time and maintenance. In practice, a correctly set coupling prevents sudden overloads on the tap, preserving thread quality and extending component service life while maintaining production rhythm.

Reliable transmission via the square shank for clean torque transfer

Torque is transmitted through the shaft square, ensuring a positive drive and minimising torsional play during threading. The combination of a 22 mm body diameter with an 18 mm square provides a stable connection suitable for standard tapping fixtures. This means consistent cutting conditions and reproducible results in both single-station and multi-spindle setups. The secure mechanical interface supports higher process reliability and reduces the risk of misalignment-related tool wear.

Designed for compatibility with DIN 374/376 M30 and modular workflows

Compatibility with DIN 374/376 M30 makes the unit suitable for many industrial tapping applications. Different shank sizes require corresponding inserts, allowing workshops to assemble a modular set tailored to the machine and tap shank used. The modular approach streamlines tool change routines and reduces inventory complexity: one coupling type serves several tap families when paired with the appropriate insert, improving operational flexibility.

Compact dimensions for straightforward integration into existing tool chains

The compact overall dimensions and clear specification of critical lengths facilitate installation and space planning in toolholders and tapping heads. Key dimensions such as L3: 41 mm, L4: 55.5 mm and D: 72 mm define the envelope required for mounting and ensure compatibility with common tapping units. Clear dimensional data aids engineers when designing fixtures or selecting spindles, reducing trial fits and accelerating setup times on the shop floor.

FAQ

What is the primary purpose of this quick-change insert?
The TECWERK quick-change insert is designed to limit torque during tapping operations and thereby protect taps from breakage while ensuring consistent thread quality.

Which tap standards is the insert compatible with?
The insert is suitable for taps conforming to DIN 374/376 M30 and is intended for use where that thread interface is specified.

How does the adjustable safety coupling improve production reliability?
By setting a defined torque threshold, the coupling slips before the tap is overloaded, reducing unexpected tool failure and improving overall machine uptime.

Are different shank sizes supported with the same coupling?
Yes, the coupling transmits torque via the shaft square, and different inserts are required for different shank measurements to ensure a secure fit.

What are the key dimensions to verify before installation?
Refer to the core measurements such as D, D1, L1, L3, L4, L5 and the shank square (18 mm) to confirm compatibility with the intended toolholder and tapping head.
