TECWERK E2 Toolholder for Boring Bars (VDI40, Clamping Ø 40 mm)

The TECWERK E2 toolholder is a Form E2 clamping solution for boring bars, designed for DIN 69880-compatible VDI40 interfaces and fitted with both internal and external coolant supply

• Internal and external coolant supply
• Clamping diameter 40 mm
• Form E2, DIN 69880 compatible
• Cylindrical shank for simple installation

Secure clamping with controlled coolant flow

The E2 design provides consistent clamping for boring bars with a nominal clamping diameter of 40 mm, ensuring secure axial and radial support during machining. Built to the DIN 69880 interface, the holder mates with standard VDI40 tool turrets to preserve alignment and repeatability across setups. The combination of internal and external coolant supply improves cooling at the cutting edge and supports chip evacuation, which helps to maintain cutting-edge life and process stability. Where accuracy matters, the mechanical fit and standard interface reduce runout and variation between cycles.

Faster setup and less preparation for the bar

A practical benefit of this holder is that no material removal of the bar is required before installation: no shortening of the boring bar necessary. The carrier accepts boring bars with a cylindrical shank, allowing rapid exchange and fewer preparatory steps on the shop floor. For production environments that value throughput, the simplified handling and standardised mounting cut changeover time and reduce error sources. The toolholder is not through-drilled, so coolant routing is designed to match common machine tool coolant schemes while retaining the holder’s mechanical integrity.

Built for dependable machining cycles

This toolholder combines robust mechanical design with features that support repeatable operations and serviceability. The Form E2 geometry and VDI40 compatibility provide predictable positioning for finishing and roughing passes, while integrated coolant channels give process engineers choices for optimising tool life. Although compact, the holder’s dimensions and interfaces are selected to balance stiffness with accessibility, making it suitable for a wide range of boring tasks where stability and precision are required. Documentation and measured interfaces support straightforward integration into existing tool setups.

FAQ

Is the holder compatible with VDI40 tool turrets?
Yes. The TECWERK E2 toolholder is designed for VDI40 interfaces and conforms to DIN 69880, ensuring compatibility with standard VDI40 tool turrets; SKU 2000833685NW identifies this specific configuration.

Does the toolholder require the boring bar to be shortened before use?
No. One of the practical advantages of this E2 holder is that no shortening of the boring bar is necessary, allowing immediate installation of bars with a cylindrical shank.

Can coolant be supplied through the holder?
Yes. The design offers internal and external coolant supply. Note that the carrier is specified as not through-drilled, so coolant routing follows the holder’s channel configuration rather than a through-hole bore.

What are the key dimensions to check before ordering?
Key dimensions include clamping diameter d2 = 40 mm, overall length l6 = 90 mm and flange-related measures d6 = 83 mm / d8 = 82 mm; these values are listed for planning the assembly with machine fixtures.

For which applications is this toolholder intended?
The holder is specified for use with boring bars and is intended for turning and boring operations where a standardised VDI40 connection and controlled coolant delivery improve process stability and repeatability.
