Quick-change insert SE 8 mm x 6.2 mm, Size 1 – TECWERK

A Quick-change insert SE designed for secure holding of taps and fast swaps in production and workshop environments, compatible with DIN 371 M8 tap applications.

• Quick-change system for rapid tool swaps
• Torque via 6.2 mm square shank drive
• Compatible with DIN 371 M8 tapping tools
• Compact Size 1 for tight toolholders

Faster changeovers that keep production moving

The quick-change insert concept focuses on efficiency: taps are held by a quick-clamping device, allowing swift replacements without time-consuming re-clamping. Because the insert is specified for DIN 371 M8, it fits established tap geometries and reduces the need for special tooling. For workshops where every minute of spindle time matters, the reduced setup and tool-change time translates directly into improved throughput. The compact design also minimises the space required in toolholders, helping maintain line density without compromising accessibility.

Secure torque transmission for precise threads

Torque is transmitted via the square shank (6.2 mm), which provides a positive drive and lowers the risk of slippage during tapping cycles. The insert is supplied without a safety coupling, so torque transfer is direct and immediate—suitable for controlled production environments where a positive drive is required. The direct transfer method supports consistent thread quality and repeatability, while the standardised drive geometry simplifies integration into existing holders and spindles.

Dimensions and mechanical compatibility explained

Key dimensions are provided to ensure correct selection and fit: D: 30 mm, D1: 19 mm, L1: 18.5 mm, L3: 4 mm, L4: 21.5 mm, L5: 7 mm. These measurements define the insert’s envelope and engagement depth, making it straightforward to verify clearance and reach for specific tapping operations. Where different shank sizes are used, matching inserts are required to maintain the intended torque path and clamping interface; this modular approach keeps inventories lean while offering flexibility across a range of threaded operations.

Practical considerations for purchase and deployment

The insert is delivered as a single unit (packaging unit: 1), allowing precise inventory control for production planners. Because the component is intended for use with taps held in a quick-clamping device, ensure the holder and the tap meet DIN 371 specifications for optimum performance. For workshops seeking reliable sourcing and consistent quality, Metav’s distribution from Emmerich ensures dependable supply and a broad range of compatible toolholders and replacement inserts.

FAQ

Is this insert compatible with all M8 taps?
Compatibility depends on the tap complying with DIN 371 M8 dimensions; the insert is designed to work with taps that meet that standard and with holders using the specified quick-clamping interface.

How does the 6.2 mm square shank affect performance?
The 6.2 mm square shank provides direct torque transmission and reduces slippage compared with cylindrical drives, supporting consistent thread quality during repetitive tapping cycles.

Can the insert be used with a safety coupling?
This version is supplied without a safety coupling; where torque-limiting protection is required, pairing with a compatible coupling or selecting an alternative insert designed for torque release is recommended.

What should be checked before fitting the insert?
Verify the holder’s quick-clamping mechanism, the tap’s DIN 371 conformity and the required engagement lengths (see L1, L4, L5) to ensure correct fit and reach.

Is the insert suitable for automated tapping machines?
Yes—when the machine’s holder and the tap conform to the same standards. The direct square-shank drive is appropriate for controlled automated cycles where a positive torque transfer is desired.
