Collet Spanner ER 250 (ER 25) — TECWERK, hardened & zinc-plated

The Collet Spanner ER 250 (ER 25) is a workshop tool designed for secure tightening of ER/ESX collet nuts in machining and toolroom applications, compliant with DIN 6499.

• Secure clamping of ER/ESX collet nuts
• Hardened, zinc-plated special steel construction
• Designed for ER 25 collet systems
• Built-in hanging hole for convenient storage

Precision clamping that supports consistent machining results

The span key is engineered for reliable torque application when securing ER/ESX collet nuts; its compatibility with DIN 6499 ensures correct fit and repeatable clamping performance across standard collet systems. Manufactured from special steel that is hardened for wear resistance and zinc-plated for corrosion protection, the tool reduces the risk of slippage and deformation during routine use. This results in fewer re-adjustments, less downtime and a more predictable machining process — a direct efficiency advantage in production and maintenance environments.

Durable design for a long service life and low maintenance

Constructed with longevity in mind, the spanner’s hardened core resists rounding and mechanical wear, while the zinc-plated finish provides an added layer of corrosion resistance in mixed workshop conditions. The robust material choice minimises the need for frequent replacement and helps contain operating costs over time. By selecting a tool that resists wear, the workshop benefits from consistent clamping accuracy and reduced spare-part turnover — practical advantages that support steady productivity.

Ergonomic handling and organised storage for faster workflows

The tool’s form factor supports quick engagement with ER 25 collet nuts, allowing for efficient operation during routine changeover and maintenance tasks. A practical hanging hole is incorporated for easy storage at the bench or on pegboards, keeping the tool accessible and reducing search time. Clear labelling of the key size and the simple, sturdy construction mean less guesswork during busy shifts, helping to streamline workflow and improve operator satisfaction.
