Tool holder for boring bars, Form E2 (VDI40) – TECWERK, DIN 69880, 25 mm clamping

Tool holder for boring bars, Form E2 designed for cylindrical-shank boring bars with both internal and external coolant supply for precision turning and boring applications.

• Form E2 for cylindrical shank
• Internal and external coolant supply
• Clamping diameter 25 mm
• Compatible with VDI40 spindles

Secure clamping that maintains concentricity and repeatability

A high-precision Form E2 holder delivers stable, repeatable clamping for cylindrical-shank boring bars, improving surface finish and dimensional accuracy in serial production. The combination of a 25 mm clamping diameter and the VDI interface ensures a firm fit in standard tool turrets, reducing run-out and vibration. Compliance with DIN 69880 provides interchangeability across machines that use VDI tool holders, simplifying tool inventory and ensuring consistent results on lathes and turning centres.

Integrated coolant routing minimises thermal distortion and tool wear

The integrated internal and external coolant channels feed cutting fluid close to the cutting edge without modifications to the bar, which helps control cutting temperatures and evacuate chips more effectively. Because the design requires no shortening of the boring bar, set-up time is reduced and the original bar length is retained for future operations. This configuration supports higher productivity and longer tool life, particularly in demanding finishing operations where thermal stability is critical.

Designed for straightforward compatibility and dependable shop-floor performance

Built for compatibility with VDI40 systems and cylindrical shank bars, the holder is a practical choice for workshops aiming to standardise tooling across multiple machines. The robust construction and standard dimensions mean fewer changeovers and a lower risk of incompatible assemblies. For maintenance teams, the simple geometry eases inspection and reconditioning, while the standardised interface supports a predictable supply chain and fast replacement when needed.

FAQ

Is this holder compatible with VDI40 tool turrets?
The TECWERK tool holder is built for the VDI40 interface and is compatible with standard VDI40 tool turrets that follow DIN 69880.

Can coolant be supplied through the holder to the cutting edge?
Yes, the holder offers both internal and external coolant supply channels to deliver cutting fluid close to the tool without modifying the boring bar.

Is it necessary to shorten the boring bar before use?
No shortening of the boring bar is required; the holder accepts cylindrical-shank boring bars in the specified clamping diameter.

Which clamping diameter suits common boring bars?
This holder is specified for a 25 mm clamping diameter (d2), matching bars manufactured to that nominal size.
