Quick-change insert SES 4.5 mm x 3.4 mm, Size 1 for DIN 374/376 M6 (TECWERK)

The Quick-change insert SES 4.5 mm x 3.4 mm, Size 1 is a compact replacement insert designed for tapping operations with DIN 374/376 M6 taps, featuring an adjustable safety clutch for torque limitation.

• Adjustable safety clutch prevents tap breakage
• Torque transmission via shaft square interface
• Compatible with DIN 374/376 M6 taps
• Compact Size 1 for small shank interfaces

Prevents tap breakage and protects production

The central advantage of this quick-change unit is the adjustable safety clutch, which limits torque at the drive end and thereby prevents sudden tap fractures during demanding threading tasks. By decoupling excessive torque, the component reduces the risk of scrapped workpieces and machine stoppages, improving process reliability and cutting tool life. This results in fewer interruptions and a steadier production flow for small-batch and series operations alike.

Reliable torque transfer for defined thread quality

Torque is transmitted through the square shank interface, ensuring positive drive without slippage under normal operating loads. The insert is specified with a 4.5 mm diameter and a 3.4 mm square connection, matching the mechanical requirements of the listed tap standard. This construction yields consistent thread formation, particularly important when machining steels or mixed materials where controlled torque prevents tap overload and preserves thread accuracy.

Compact dimensions for easy integration in tool holders

With compact axial dimensions (for example L3: 24.5 mm, L4: 21.5 mm, L5: 25.5 mm) the insert minimises overhang and fits standard quick-change systems for small shafts. The small footprint reduces bending moments and supports more accurate alignment in the spindle or holder; this is especially useful in confined fixtures or multi-spindle arrangements. The Size 1 form factor means the unit is intended for lighter-duty tapping installations where space and precision matter.

Designed for industrial use and broad workshop relevance

Engineered to work with taps conforming to DIN 374/376 M6, the insert is suited to maintenance shops, tool rooms and production lines where repeatable results are required. The torque-limiting feature is particularly effective when tapping blind holes or interrupted cuts, lowering the incidence of tap breakage and attendant downtime. The overall design reflects workshop realities: robust torque control, straightforward interchangeability and compatibility with different shaft measures via dedicated inserts.
