Precise, repeatable clamping for stable machining

The E2 toolholder is designed to deliver consistent axial and radial positioning for cylindrical-shank boring bars, meeting the DIN 69880 specification for standardised interfaces. The robust clamping for Ø25 mm bars prevents slippage under load and reduces run-out, which in turn protects the cutting edge and keeps components within tolerance. For workshops seeking reliable repeatability across batches, this holder translates into fewer reworks and predictable cycle times, supporting a smoother production flow and better overall process control.

Integrated coolant routing that protects tools and surfaces

Equipped with internal and external coolant feed, the holder improves coolant delivery directly to the cutting zone, enhancing chip evacuation and heat control. Better coolant routing reduces thermal expansion at the cutting edge and helps maintain surface finish without additional fixtures. Because no shortening of the boring bar is necessary, setup is faster and concentricity remains uncompromised; this minimises handling and the risk of setup errors, contributing to longer tool life and reduced consumable costs.

Compatibility and efficient workshop integration

Built for VDI30-equipped tool turrets and machining centres, the holder suits standardised setups and integrates into existing toolchange systems without modification. The E2 form and dimensional conformity simplify tool management and inventory planning. Clear technical specifications and adherence to recognized norms make procurement and qualification straightforward, while the compact design supports tight tool layouts and maximises turret space utilisation for multi-operation machining strategies.

Application reassurance and service orientation

For production environments processing a variety of steels, aluminium and cast materials, the holder’s standard interface and coolant capability make it a versatile option for roughing and finishing passes with boring bars. Metav’s position as a precision partner ensures transparent delivery and advice: product selection is supported by factual compatibility data and practical recommendations for clamping practice and coolant pressures, helping to match the holder to the application without ambiguity.

FAQ

How does the holder manage coolant supply?
The holder provides both internal and external coolant feed, enabling directed coolant flow to the cutting zone to improve chip removal and temperature control for the boring bar.

Is the holder compatible with VDI tool turrets?
Yes, the holder is designed for the VDI30 interface and conforms to DIN 69880, making it compatible with VDI30-equipped turrets.

Can the boring bar be shortened after installation?
Shortening the boring bar is not required; the holder is designed so that no bar shortening is necessary, which speeds setup and preserves concentricity.

What clamping size does the holder accept?
The clamping diameter is 25 mm, intended for cylindrical-shank boring bars with that shank dimension.

What is the article number for ordering and reference?
