Quick-change insert SES 20 mm x 16 mm, Size 3 — adjustable safety clutch, for DIN 374/376 M27 (TECWERK)

The Quick-change insert SES 20 mm x 16 mm (Size 3) is a tapping accessory engineered to limit torque and protect taps during manual and machine tapping applications compliant with DIN 374/376 M27.

• Adjustable safety clutch for torque limitation
• Prevents tap breakage during tapping operations
• Torque transmission via 16 mm four-square shank
• Compatible with DIN 374/376 M27 taps

Controlled torque to prevent tool failure

The core advantage is the adjustable safety clutch which limits the torque applied to the tap, preventing sudden overloads and the consequent tap breakage. This function converts an unpredictable failure mode into a manageable operational parameter, lowering scrap rates and downtime. The torque is transferred via a four-square shank, ensuring direct, backlash-free transmission to the tap shank for consistent thread quality. For technicians unfamiliar with torque-limiting systems: the clutch disengages when the preset torque threshold is reached, protecting both the tap and the workpiece while allowing rapid continuation of the process.

Standardised fit for common tapping tasks

Designed around industry standards, the insert suits taps manufactured to DIN 374/376 M27 and is prepared for workshop environments where repeatable fits are essential. The 20 mm diameter working face and the 16 mm square shank provide a compact interface that matches common drive systems. Because torque is taken through the square shank, different drive sizes require the corresponding insert variants; this modular approach maintains secure engagement and simplifies stock management when multiple shank standards are in use.

Compact dimensions that integrate easily into tool setups

The component’s geometry is optimised for insertion and removal in quick-change systems without compromising strength. Key dimensions (detailed below) show a compact profile suitable for tight assemblies while offering sufficient mass to stabilise the tap during engagement. The design keeps the centre of mass close to the drive axis, which reduces eccentric loads and supports consistent thread formation. Workshop operators benefit from reduced setup complexity and straightforward replacement when different shank sizes are required.

Operational reliability and workflow benefits

Integrating an insert with a torque-limiting mechanism translates directly into operational gains: fewer broken taps, fewer interrupted cycles and a safer working environment. The straightforward mechanical concept requires no electrical supply and is low-maintenance, making it a pragmatic choice for busy production floors. When paired with Metav’s distribution and advisory services, the solution supports predictable supply, technical guidance and a single-source procurement model that simplifies tooling logistics.

FAQ

What safety function does this insert provide?
The insert incorporates an adjustable safety clutch which limits torque to protect taps from overload and to reduce the risk of tap breakage during tapping operations.

Is the insert compatible with standard M27 taps?
Yes, the insert is intended for use with taps to DIN 374/376 M27 and is designed to interface via a 16 mm square shank.

How is the torque transmitted to the tap?
Torque is transmitted directly through the four-square shank, providing a positive drive with minimal play for reliable thread cutting.

Are different shank sizes available?
Different shank sizes require matching inserts; the current item uses a 16 mm square drive and other sizes must be ordered as separate insert variants.

Where can the exact dimensions and specification be found?
Exact dimensions, including L1, L3, L4, L5, D and D1, are provided above in the technical data and support accurate integration into existing tooling setups.
