60mm E2 Tool Holder For Boring Bars Through-Coolant, 12mm Shank, DIN 69880 - TECWERK

Benefit from the combination of internal and external coolant supply, a through-drilled design, and standardised VDI30 clamping to keep machining uninterrupted and accurate; order the TECWERK Form E2 tool holder directly via Metav Werkzeuge or consult the Metav specialists if required.

TECWERK Form E2 tool holder for boring bars – clamping Ø 12 mm, VDI30

The TECWERK Form E2 tool holder is a DIN 69880-compliant holder for boring bars, engineered for through-coolant machining and stable clamping in CNC turning and boring operations

• Form E2, DIN 69880 standardised design
• Internal and external coolant supply
• Through-drilled — no bar shortening required
• Cylindrical shank VDI30, clamping Ø 12 mm

Consistent concentricity and repeatable clamping for production runs

The Form E2 interface delivers repeatable clamping and reliable positional accuracy for turning and boring cycles. With the VDI30 cylindrical shank and a clamping diameter of 12 mm, the holder ensures concentric seating of the boring bar, which reduces runout and minimises rework. Engineers benefit from predictable tool behaviour across batches, translating into shorter set-up times and fewer scrap parts in continuous production.

Continuous coolant flow for longer tool life and fewer interruptions

A through-drilled design with internal and external coolant supply enables efficient coolant delivery directly to the cutting zone while supporting external nozzle use when required. This dual-option coolant arrangement improves chip evacuation and cooling, lowering thermal load on carbide or HSS inserts and extending tool life. The absence of required bar shortening preserves original bar length, reducing preparation time and keeping spindle balance intact for uninterrupted machining.

Seamless integration into existing turret and toolpost systems

Designed for use with standard boring bars, the holder’s cylindrical shank (VDI30) simplifies integration into turret-style tool systems and quick-change stations. The normative DIN 69880 compatibility aids inventory management by aligning with existing toolholder standards, reducing the variety of interfaces on the shop floor. If a workshop requires advice on mounting or matching the holder to a specific bar system, Metav’s technical consultants can provide guidance to ensure straightforward implementation.

FAQ

What interface does this holder use and which bar sizes are compatible?
The TECWERK Form E2 tool holder (SKU 2000833673NW) uses a VDI30 cylindrical shank interface and is specified for a clamping diameter of 12 mm, matching standard boring bars designed for that bore.

Is coolant supplied internally or externally with this holder?
This holder supports both internal and external coolant supply; the through-drilled construction allows coolant to reach the cutting zone internally while still permitting external nozzle use.

Does the design require shortening the boring bar before installation?
No shortening of the boring bar is required—the through-drilled execution and clamping arrangement permit the bar to be used at its original length, preserving setup flexibility and balance.

Which standard ensures interchangeability of this tool holder?
Interchangeability is based on DIN 69880 compliance and the Form E2 interface, facilitating straightforward replacement within systems that observe the same standard.

Can this holder be used in turret systems and quick-change stations?
Yes, the cylindrical VDI30 shank and standardised form make the holder suitable for turret-style systems and many quick-change stations compatible with VDI interfaces.
