Quick-change insert SES 25 mm x 20 mm Size 3 by TECWERK — adjustable safety coupling for torque limiting

Quick-change insert SES 25 mm x 20 mm Size 3 is a compact tap-holding insert designed for use with taps to DIN 374/376 M33 in production and workshop settings, combining secure clamping with an integrated safety coupling.

• Adjustable safety coupling for torque limiting
• Prevents tap breakage in interrupted cuts
• Torque transmitted via 20 mm square shank
• Compact 25 mm diameter for tight tool setups

Minimise tap failure and keep production moving

The adjustable safety coupling built into this quick-change insert is engineered to protect taps from overload by limiting transmitted torque. When a predetermined torque is exceeded, the coupling disengages so that a forced fracture of the tap is avoided; this mechanism is particularly useful when machining interrupted threads or when chip‑control is unpredictable. The result is fewer tool replacements and more consistent cycle times. The insert’s torque-limiting function is easy to set and, because the torque is transferred through the 20 mm square shank, the drive path remains direct and reliable under normal operating conditions.

Fast changeover and secure clamping for busy toolrooms

Designed for quick tool changes, the insert fits into standard holders where a 20 mm square drive is specified and presents a 25 mm diameter body that is compact enough for confined setups. The mechanical interface transmits power via the shank square, ensuring minimal backlash and predictable stiffness; for different holder drives, matching inserts are required, which allows flexible integration into varied tool racks and spindle adaptors. Clear, standard dimensions (L3, L4, L5, D, L1, D1) support planning and reduce errors during tooling changes, contributing to faster set-ups and reduced idle time.

Built for production use and straightforward servicing

This insert was conceived for professional environments where reliability and maintainability are paramount. The mechanical safety function reduces the risk of costly thread‑tap failures and repeat machining, which improves overall process yield. Routine inspection is limited to visual checks of the coupling and shank engagement; replacement is straightforward when wear occurs, so maintenance intervals can be planned rather than urgent. The compact design also supports nested or multi‑axis fixtures where space is at a premium.

Application suitability and practical benefits

Compatibility with DIN 374/376 M33 means the insert is suitable for thread‑cutting operations specified to that standard, while the torque‑limiting feature makes it a sensible choice for mixed batches and varied material conditions. The combination of precise torque control and standardised shank interface helps stabilise production outputs and reduces scrap rates. For workshops seeking to rationalise tooling without sacrificing safety, the insert offers a pragmatic balance between performance and operational resilience.

FAQ

What types of taps are compatible with this insert? The Quick-change insert SES 25 mm x 20 mm Size 3 from TECWERK is compatible with taps made to DIN 374/376 M33; the torque is transmitted via the 20 mm square shank and the insert is intended for that thread specification.

How does the adjustable safety coupling work? The adjustable safety coupling in the insert disengages when a preset torque threshold is exceeded, limiting transmitted torque to protect the tap from breaking and reducing the need for unplanned tool changes.

Can the torque setting be changed on the shop floor? Yes, the torque limit is adjustable; the setting procedure for the TECWERK SES insert is mechanical and designed to be performed during routine set-up by trained personnel.

Is the insert suitable for interrupted threading operations? Yes, the torque-limiting feature is specifically beneficial in interrupted threading or when cutting conditions are variable, as it helps to avoid sudden overloads that can cause tap fracture.

Are matching inserts needed for different holders? Different drive or shank dimensions require corresponding inserts; the SES series uses the square shank for torque transmission, so inserts must match the holder’s shank size.
