Quick‑change insert SES 6 mm × 4.9 mm Gr.1 for DIN 371 M5 – TECWERK with adjustable safety clutch

Quick‑change insert SES 6 mm × 4.9 mm Gr.1 for DIN 371 M5 is a size‑1 quick‑change tapping insert designed for machine and workshop tapping operations where controlled torque and fast changeovers are essential

• Adjustable safety clutch for torque limitation
• Prevents tap breakage during threading
• Torque transmission via shank square
• Compact design for tight installation spaces

Protects taps and reduces unplanned downtime

The core advantage of this insert is its adjustable safety clutch, which limits applied torque and hence greatly reduces the risk of tap breakage during interrupted cuts or misfeeds. Where conventional toolholders transfer full spindle torque, this SES unit interrupts overloads, preserving both expensive taps and workpieces. Because the torque is transmitted via the shank square, the drive between holder and cutter remains secure under normal cutting loads while disengaging when a preset torque is exceeded, delivering consistent machine uptime and fewer changeovers due to tool failure.

Reliable mechanical connection and clear compatibility

The insert is configured for a 6 mm receiving diameter with a 4.9 mm square drive compatible with DIN 371 M5 taps, ensuring correct mechanical fit and standardised engagement. The design requires the matching insert for different shank sizes, simplifying inventory management: one holder family, multiple specific inserts. The compact geometry (see technical data) aids installation in confined heads and tapping arms. By using a standardised interface and torque safety, the system supports reproducible tapping results and predictable tool life — essential for batch production and quality control.

Practical dimensions and workshop integration

Key dimensions are provided for quick planning and integration: L1 and L3 relate to insertion depth and exposed length for collision checks, while D and D1 indicate the outer form for clamping and clearance. With a compact footprint and a packaging unit of 1, the insert is straightforward to trial and stock. The construction concentrates benefit on operational reliability: fewer broken taps, reduced scrap rates and more consistent thread quality. For shops seeking a pragmatic balance of safety and productivity, this insert provides a focused solution without complex retrofit work.

FAQ

What is the primary safety feature of this insert?
The insert uses an adjustable safety clutch to limit torque and reduce the likelihood of tap breakage when using the TECWERK SES size 1.

Which tap standard is this insert compatible with?
This quick‑change insert is compatible with DIN 371 M5 taps and is specified for a 6 mm receiving diameter with a 4.9 mm square drive.

How does torque get transmitted through the unit?
Torque is transmitted via the shank square, ensuring secure drive transfer under normal cutting conditions and safe disengagement at overload.

Are there different sizes available for other shank dimensions?
Yes, the design requires different inserts for alternative shank sizes; the TECWERK SES family provides matching sizes to suit various drives.

Which dimensions are relevant when checking for machine clearance?
Use the provided geometric figures (for example L1, L3, D and D1) from the technical data to verify installation space and collision clearances for the SES unit.
