20mm Tool Holder E2 With Internal And External Coolant Through 83mm, DIN 69880 - TECWERK

Take advantage of the secure clamping of the Form E2 design combined with the VDI40 interface and integrated coolant paths for consistent machining results; the through-drilled construction and 20 mm boring-bar capability reduce setup time and avoid unnecessary modifications to tooling. Order the holder directly via Metav Werkzeuge or consult our specialists for application advice.

TECWERK Tool holder E2 VDI40 for 20 mm boring bars

The TECWERK tool holder E2 VDI40 is a standard-compliant clamping solution for boring-bar applications, designed to secure 20 mm bars with axial coolant supply for precise internal machining in workshop and production environments.

• Form E2 design for secure seating
• VDI40 interface for standard toolholders
• Internal and external coolant supply
• No shortening of boring bar required

Stable clamping for repeatable boring results

The E2-style holder is engineered for consistent axial alignment and minimal runout, making it suitable where repeatable hole geometry is required. Its VDI40 interface provides compatibility with common CNC tool turrets and adaptors, while the cylindrical shank design ensures a reliable fit in standard spindles. The arrangement minimises vibration and supports longer tool life, so operators benefit from fewer regrinds and more predictable cycle times. The construction focuses on functional precision rather than decorative finishes, delivering measurable improvements in process stability.

Effective coolant routing to protect inserts and workpieces

Integrated internal and external coolant supply channels permit targeted flushing at the cutting edge, removing chips and reducing thermal load during deep boring operations. The through-drilled design allows coolant to reach the bar tip directly, which helps maintain cutting-edge integrity and reduces the risk of built-up edge or workpiece distortion. Effective coolant management translates into lower scrap rates and fewer secondary operations, supporting a more efficient production flow and less manual intervention between operations.

Designed for quick setup and workshop integration

Compatibility with the DIN 69880 standard and the nominal 20 mm bar diameter simplify tool selection and mounting in mixed fleets. The holder’s geometry eliminates the need to shorten the boring bar prior to insertion, saving assembly time and preserving bar length for future use. With straightforward dimensions and standard interfaces, the component slots into existing toolholders and changeover routines with minimal adjustment, helping to reduce machine downtime and streamline daily workflows while supporting high-precision results.

FAQ

Is this holder compatible with standard VDI turrets?
The TECWERK tool holder E2 VDI40 is designed for VDI40 interfaces and fits standard VDI turrets that accept that interface size.

Can coolant be supplied through the tool holder?
Yes, the holder provides both internal and external coolant supply via a through-drilled channel to the boring bar tip.

Does the boring bar require modification before mounting?
No, shortening of the boring bar is not required; the holder accepts a 20 mm bar without additional machining.

Which standard governs this holder’s interface and form?
The holder conforms to DIN 69880 and uses the Form E2 specification for axial mounting and compatibility.

What benefits does the through-drilled design bring?
Through-drilled coolant delivery improves chip evacuation and reduces thermal stress at the cutting zone, which supports longer tool life and better surface finish.
