Quick-change insert SES 6 mm × 4.9 mm Size 2 — adjustable safety clutch, for DIN 374/376 M8 (TECWERK)

The Quick-change insert SES 6 mm × 4.9 mm Size 2 is a compact tapping adapter designed to limit torque and prevent tap breakage in M8 applications while allowing rapid tool swaps.

• Adjustable safety clutch for torque limitation
• Reduces tap breakage during tapping
• Torque transmission via 4.9 mm shank square
• Compatible with DIN 374/376 M8

Safer tapping through adjustable torque control

The integrated adjustable safety clutch provides a defined torque limit so the tapping process stops before a tap is overstressed, significantly lowering the risk of tap breakage. By transferring torque through the shank square, torque delivery is direct and measurable; this reduces slippage compared with softer drive connections. For workshop planners this means fewer scrap threads and less downtime for rework. The mechanism is particularly advantageous where fragile or hardened workpieces are present, because a predictable torque cut-off protects both tool and component.

Faster changeovers and consistent fit in assembly lines

Designed as a quick-change solution, the insert allows rapid replacement of tapping tools to maintain cycle times on production lines. The adapter is intended for use with standard M8 taps specified to DIN 374/376, so integration into existing processes is straightforward. Note that different shank dimensions require corresponding inserts, which simplifies inventory control when shank sizes are standardised. The listed dimensions (L3: 30.5 mm, L4: 35 mm, L5: 34 mm, D: 50 mm, L1: 32 mm, D1: 31 mm) assist engineers in verifying correct fitment in toolholders and collets.

Practical reliability for the everyday workshop

Built to support repetitive tapping tasks, the unit helps reduce tool-related stoppages and supports predictable production throughput. Supplied as a single unit, it suits small-batch repairs as well as larger runs when combined with a stock of compatible inserts. The sturdy design and torque-limiting feature combine to protect skilled operators and valuable taps, lowering replacement costs and increasing overall equipment effectiveness.

FAQ

Is this insert compatible with M8 taps specified to DIN 374/376?
The Quick-change insert SES 6 mm × 4.9 mm Size 2 from TECWERK (SKU 4000832675NW) is designed specifically for use with taps conforming to DIN 374/376 M8.

How does the adjustable safety clutch protect taps?
The adjustable safety clutch on the SES insert limits torque transmission so the tool disengages before excessive load causes tap breakage, protecting both the tap and the workpiece during a blocked thread or sudden overload.

Can the same insert be used with different shank sizes?
Different shank dimensions require corresponding inserts; the SES system needs a matching shank size, so the TECWERK insert must be paired with the correct counterpart for reliable torque transfer.

What are the key dimensions to check for toolholder compatibility?
Check the listed core dimensions (L3, L4, L5, D, L1, D1) against the toolholder and collet specifications to ensure correct seating and engagement for consistent torque transmission.

What is included in the packaging?
The product is supplied as a single unit (packaging unit: 1) and is ready for installation into the appropriate toolholder or quick-change system.
