Quick-change insert SE 6 mm × 4.9 mm (Size 2) by TECWERK

The Quick-change insert SE 6 mm × 4.9 mm (Size 2) is a compact holder designed to retain thread taps via a quick-clamp system for efficient tapping to DIN 371 and DIN 374/376 standards

• Quick-change retention for thread taps
• Shaft square 4.9 mm for direct torque transfer
• Compatible with DIN 371 M5–6 and DIN 374/376 M8
• Compact 6 mm insert — Size 2 geometry

Faster tapping and reduced setup time

The Quick-change insert SE 6 mm × 4.9 mm (Size 2) speeds up tool changes by keeping taps clamped in a quick-change nest rather than requiring time-consuming retooling of the spindle. The insert’s design focuses on throughput: secure retention of the tap enables repeatable starts and consistent thread form, while the compact footprint helps to save valuable spindle clearance. As a result, production cycles become more efficient and changeover losses are minimised, supporting continuous operation in both workshop and small-series production environments.

Secure torque transmission with precise geometry

The quick-change module transfers drive force through a shaft square 4.9 mm, which provides direct and measurable torque transfer to the tool shank. The absence of a safety clutch (no safety coupling) means torque is transmitted without slip, delivering predictable cutting behaviour when paired with appropriate taps and machinery. Specified geometry values such as L4: 35 mm, L1: 32 mm and L5: 11 mm contribute to stable axial positioning and alignment, reducing wobble and improving thread accuracy over repeated cycles.

Broad compatibility for standard thread taps

Designed for common thread standards, this insert accepts taps for DIN 371 M5–6 and DIN 374/376 M8, making it suitable for a wide range of metric tapping tasks. The system requires matching inserts for different shank sizes, so workshops can build a modular set to cover multiple tap diameters and thread types. The result is a versatile, standard-compliant solution that integrates with existing toolholders and quick-change fixtures without major retrofitting.

Practical integration and service benefits

Installation is straightforward: the insert is intended for use in housings where taps are retained by the quick-clamp device and the square shank engages the holder for drive transmission. Dimensional values such as D: 48 mm and D1: 31 mm support consistent seating in compatible fixtures, and a single-piece packaging unit simplifies stock handling. With its Grade 2 sizing and compact form, the module reduces inventory complexity while enabling rapid replacement, supporting steady production and predictable maintenance intervals.

FAQ

Which tap sizes and standards does this insert support?
The Quick-change insert SE 6 mm × 4.9 mm (Size 2) is compatible with taps to DIN 371 M5–6 and DIN 374/376 M8 (SKU 4000832640NW), ensuring direct use with those metric thread types.

How is torque transmitted and is there a safety coupling?
Torque is transmitted through the shaft square 4.9 mm for direct transfer; the insert is specified without safety clutch, so torque is delivered without slip for predictable tapping performance.

Can different shank dimensions be used with this insert?
The module is designed for a 4.9 mm square drive; different shank sizes require correspondingly sized inserts, allowing a modular set-up for workshops needing multiple shank dimensions.

What are the critical dimensions for fixture planning?
Relevant dimensions include L4: 35 mm, L1: 32 mm, L5: 11 mm, D: 48 mm and D1: 31 mm, which support correct seating and alignment in compatible quick-change housings.

Is this insert suitable for high-volume production?
The quick-change design and direct torque transfer of this SE insert make it suitable for repetitive tapping operations where rapid tool changes and consistent thread quality are required.
