Quick-change insert SE 16 mm × 12 mm (Size 2) — for DIN 374/376 M20 tapping, 12 mm square shank (TECWERK)

A Quick-change insert SE 16 mm × 12 mm (Size 2) designed to secure taps in quick-clamping holders for standard DIN 374/376 M20 threading operations, offering a compact and robust connection between tap and toolholder

• Quick-change design for fast tool swaps
• Torque transmission via 12 mm square shank
• Compatible with DIN 374/376 M20 tapping

Reduce setup times with a true quick-change system

The insert's quick-change configuration is engineered to shorten tool changeover times in series production and maintenance tasks. By holding taps in a dedicated quick-clamping device, the design eliminates repeated manual tightening and adjustment, resulting in consistent positioning and rapid exchange. This saves machine downtime and boosts throughput without compromising thread quality — a pragmatic solution for workshops and toolrooms where cycle time and repeatability matter.

Secure torque transfer through a square shank interface

Torque transmission is handled via the 12 mm square shank, which provides a positive mechanical drive between holder and tap. This form-fit connection reduces the risk of slippage under load and ensures reliable rotational force for cutting threads to DIN 374/376 M20 standards. For users unfamiliar with the standard: DIN 374/376 define dimensions and tolerances for taps and corresponding fittings, meaning the insert supports established industrial threading practices and consistent results across batches.

Modular integration for diverse shank requirements

The insert is part of a modular concept in which different shank sizes are accommodated by matching inserts, allowing existing quick-change holders to be adapted rather than replaced. The absence of a safety coupling in this variant simplifies the mechanical interface and keeps the arrangement compact; where a protective shear feature is required, a different insert version should be selected. This modularity makes the solution suitable for production lines that require flexible tooling options while keeping inventory manageable.

Practical suitability for workshop and industrial use

Designed as a Size 2 insert, the component combines compact external dimensions with sturdy internal geometry, making it appropriate for confined setups and straightforward toolholder systems. The product supports efficient tapping workflows, particularly where rapid tool exchange and reliable torque transfer contribute directly to product quality and process economy. Where exact fit and minimal axial runout are essential for thread accuracy, the insert’s precise contact geometry helps maintain tolerances and reduce scrap rates.
