Toolholder E2 for drill bars (clamping Ø 16 mm, VDI30) – TECWERK

The Toolholder E2 for drill bars is a DIN 69880-compliant clamping device designed for secure mounting of drill bars in VDI30 tool interfaces, suitable for production and toolroom applications.

• Compatible with drill bars, Form E2
• Cylindrical shank, VDI30 interface
• Internal and external coolant supply
• Through-drilled; no shortening required

Precision interface for repeatable set-ups

The holder uses the standard VDI30 interface and the DIN 69880 specification to guarantee consistent alignment and concentricity when mounting drill bars. With a clamping diameter of 16 mm (d2: 16 mm) and defined seating dimensions, the design reduces runout variability that can affect hole quality. The E2 form and cylindrical shank ensure straightforward fitting in standard tool turrets and adaptors, making changeovers fast and measurable. For production environments where repeatability is essential, the standardised interface translates directly into fewer scrap parts and predictable machining results.

Efficient coolant routing for extended tool life

Integrated internal and external coolant supply channels and a through-drilled bore ensure effective coolant delivery to the cutting zone while supporting reliable chip evacuation. This arrangement prevents coolant starvation and reduces thermal stress at the cutting edge, which in turn prolongs drill-bar life and maintains hole quality over long cycles. The through-drilled configuration also eliminates the need to shorten the drill bar before mounting, saving set-up time and preserving the full working length for deeper machining tasks.

Compact, standardised form for seamless workshop integration

Designed as a compact clamping solution, the holder fits established workshop workflows and compatible toolholders without requiring special adaptors. Key dimensions such as d1: 30 mm, d6: 68 mm, d8: 55 mm, l6: 60 mm and h1: 28 mm define the envelope for installation and help planners verify clearance and interference quickly. The combination of standard interfaces and measurable dimensions supports efficient tool management: labelling, storage and replacement are simplified when toolholders conform to industry norms rather than bespoke designs.

Practical advantages for daily production and maintenance

Operational benefits include reduced set-up time thanks to the omission of drill-bar shortening and fewer adjustments due to the precise interface. The through-drilled coolant path and the dual coolant option support higher process stability and lower rework rates. Routine maintenance is straightforward: because the clamping concept follows an established standard, spare parts and replacements are widely available and compatible with existing VDI30 ecosystems. For workshops seeking predictable throughput and lower overall process variability, this clamping device is a pragmatic choice.

FAQ

What tool types are compatible with this holder? The holder is intended for drill bars and similar shank-mounted tooling; the Toolholder E2 for drill bars matches VDI30 interfaces and standard drill-bar diameters such as 16 mm.

Does the holder allow coolant through the tool? Yes. The design features both internal and external coolant supply and a through-drilled bore to deliver fluid directly to the cutting zone for improved cooling and chip control.

Is shortening of the drill bar required before mounting? No. The through-drilled arrangement removes the need to shorten drill bars before installation, preserving working length and saving set-up time with the TECWERK holder.

Which standard does the clamping system follow? The clamping device conforms to DIN 69880 and the VDI30 interface, enabling compatibility with standard tool turrets and adaptors used in many turning and milling systems.

What are the most relevant dimensions to check before fitting? Key envelope and seating dimensions include clamping diameter (d2: 16 mm), d1: 30 mm, d6: 68 mm, d8: 55 mm, h1: 28 mm and l6: 60 mm; these should be verified against the machine mounting and turret clearances.
