Quick-change insert SES 8 mm × 6.2 mm, Size 2 – Adjustable safety clutch (TECWERK)

The Quick-change insert SES 8 mm × 6.2 mm Size 2 is a compact tapping tool adapter designed for secure torque limitation and safe use with DIN 371 M8 taps in workshop and production environments

• Adjustable safety clutch for torque limitation
• Prevents tap breakage during tapping operations
• 6.2 mm square drive for solid torque transmission
• Compatible with DIN 371 M8 taps

Safer tapping through controlled torque

The core advantage of the SES quick-change insert is its adjustable safety clutch, which limits applied torque to protect taps from sudden overload. By decoupling excessive torque at the clutch setting, the risk of tap breakage is significantly reduced, especially when working in interrupted cuts or with hard materials. This torque control also lowers rework rates and preserves tooling life, resulting in a measurable increase in process reliability and lower overall downtime.

Robust drive engagement for accurate torque transfer

A secure drive connection ensures predictable performance: torque is transmitted via the 6.2 mm square drive on the shaft, providing a positive mechanical interface between the adapter and the tap holder. This method of torque transfer minimises slip and wear compared with friction-based couplings and supports consistent thread quality. Compatibility with DIN 371 M8 taps means the insert integrates with widely used tapping standards, simplifying tool selection and stock management in mixed-tool workshops.

Compact dimensions for flexible integration

The insert’s form factor supports straightforward mounting and keeps the tool train compact. Key mounting dimensions such as L1: 32 mm, L3: 30.5 mm, L4: 35 mm, L5: 34 mm, D: 50 mm and D1: 31 mm define clearance and fit in common holders and quick-change systems. These measured values allow engineers to verify seating depth and overall assembly length in CAD or on the shop floor, ensuring the adapter suits existing setups. Where different shank diameters are in use, matching inserts are required to maintain the intended drive fit and torque characteristics.

FAQ

Is this insert suitable for DIN 371 M8 taps?
The Quick-change insert SES 8 mm × 6.2 mm Size 2 is specified for use with DIN 371 M8 taps and provides a standard-compliant connection for those thread-cutting tools.

How does the adjustable safety clutch protect taps?
The adjustable safety clutch in the SES insert limits the transmitted torque to a preset threshold; when overload occurs, the clutch slips to prevent torque peaks from reaching the tap and causing breakage.

Can the same insert be used with different shank sizes?
No, the SES insert transmits torque via the shaft square and requires matching inserts for other shank dimensions; different shank sizes necessitate the corresponding quick-change insert.

What mounting dimensions should be checked before installation?
Verify the key dimensions L1 (32 mm), L3 (30.5 mm), L4 (35 mm), L5 (34 mm), D (50 mm) and D1 (31 mm) to ensure correct seating and clearance in the tool holder.
