Quick-change insert SES 8 mm x 6.2 mm (Size 1) – torque-limited for DIN 371 M8

The Quick-change insert SES 8 mm x 6.2 mm (Size 1) is a compact, torque-limited drive insert designed for protected tapping of DIN 371 M8 threads in workshop and industrial settings.

• Adjustable safety clutch reduces tap breakage
• Torque via shank square for secure drive
• Compatible with DIN 371 M8 taps
• Compact size 8 mm diameter, 6.2 mm square

Reliable tapping through controlled torque transmission

The core benefit of this insert is its adjustable safety clutch, which limits torque to prevent costly tap breakage and interruption of production. By interrupting torque transfer at a set threshold, the clutch safeguards both the tap and the workpiece; this reduces the risk of scrapped parts and extends tool life. The mechanism operates independently of the machine, providing a predictable safety margin when using hand-held or machine-driven tapping tools.

Secure connection and compatibility for consistent results

Torque transfer is achieved via the shank square, ensuring a positive mechanical drive that minimises slippage under load. The insert is specified for DIN 371 M8 taps and is supplied in Size 1 with an 8 mm diameter and a 6.2 mm shank square, so it suits standardised tapping operations. The design requires matching inserts for alternative shank dimensions, which allows workshops to standardise on the appropriate insert per shank size without compromising on drive reliability or repeatability.

Compact design with clear dimensional guidance for easy selection

The quick-change format simplifies tool changes and reduces machine downtime, while the compact geometry supports confined working spaces. Key dimensions are provided for accurate selection and setup: L3: 24.5 mm, L4: 21.5 mm, L5: 25.5 mm, D: 32 mm, L1: 18.5 mm, D1: 19 mm. These values help determine clearance and insertion depth, enabling planners and operators to verify fitment quickly. The combination of small footprint and torque control makes the insert well suited to repetitive tapping tasks in small-batch and serial production alike.

FAQ

What is the primary function of the adjustable safety clutch?
The adjustable safety clutch in the quick-change insert limits torque to protect taps and workpieces; it disconnects torque transmission when the preset threshold is exceeded.

Is this insert suitable for standard M8 taps?
Yes, the Quick-change insert SES 8 mm x 6.2 mm (Size 1) is specified for use with DIN 371 M8 taps and provides a secure drive for that thread form.

How does the insert transfer torque to the tap?
Torque is transferred via the shank square, which provides a positive mechanical connection and reduces the risk of slippage under load.

Are different shank sizes supported by the system?
The system requires corresponding inserts for differing shank dimensions; select the insert that matches the shank square required for each tapping application.
