Quick-change insert SES 3.5×2.7 mm, Size 1 – adjustable safety clutch, for DIN 374/376 M5 (TECWERK)

A Quick-change insert SES 3.5×2.7 mm Size 1 designed to limit torque during tapping and to protect M5 taps in production and workshop environments.

• Adjustable safety clutch for torque limit
• Prevents tap breakage during tapping
• Torque transmitted via shaft square
• Compatible with DIN 374/376 M5 taps

Increased process reliability through controlled torque

The insert combines an adjustable safety clutch with a compact design to deliver predictable torque transfer when tapping. By limiting torque, the unit reduces the risk of tap breakage and unplanned downtime, which improves throughput in repetitive or automated operations. The clutch setting provides a measurable safeguard: when the preset torque is exceeded, slippage occurs instead of tool failure, making the component especially valuable for brittle materials or sensitive assemblies. This results in a more stable production flow and fewer interruptions.

Straightforward integration and precise torque transfer

Designed for direct torque transmission via the square shank, the insert fits standard quick-change holders and mates with conventional tap drives to ensure secure coupling and accurate power delivery. The square interface provides positive engagement and minimises backlash during rotation, which helps maintain thread quality. The compatibility with DIN 374/376 M5 taps means the insert is ready for common metric tapping tasks; different shank sizes require dedicated inserts, allowing flexible adaptation across tool sets without compromising safety functions.

Practical advantages for workshops and production lines

The compact geometry and clearly defined dimensions make the insert easy to select and replace in both manual and machine-assisted tapping setups. The unit supports efficient tooling logistics by reducing tap breakage and the associated replacement time, contributing to lower scrap rates and improved overall equipment effectiveness. As part of a precision tooling strategy, the insert supports consistent results, which helps to maintain quality standards across batches and operators.

FAQ

What is the function of the adjustable safety clutch? The adjustable safety clutch in the SES quick-change insert limits transmitted torque so that slippage occurs before tap fracture, protecting tools and workpieces.

Which taps are compatible with this insert? This insert is compatible with taps conforming to DIN 374/376 in size M5; the design ensures correct engagement and torque transfer for those tap types.

How does the insert reduce the risk of tap breakage? By setting a torque limit on the clutch, the insert prevents overload of the tap; when torque exceeds the preset threshold the coupling slips instead of transferring damaging force.

Are other shank sizes supported with the same insert? Different shank sizes require specific inserts; the SES range includes variants to match various shaft dimensions for secure fitting.

What are the key dimensions to check before ordering? Confirm the main dimensions: insert diameter 3.5 mm, square shank 2.7 mm, overall D 32 mm and lengths L1 18.5 mm, L3 24.5 mm, L4 21.5 mm, L5 25.5 mm; refer to article number 4000832660NW for exact match.
