62mm Tool Holder For Boring Bars Form E2S Slotted, DIN 69880 - TECWERK

Take advantage of the combination of robust vibration damping and a VDI30 interface with a 32 mm clamping diameter for stable boring results and uninterrupted production flow; order the holder directly via Metav Werkzeuge or consult our specialists for integration advice.

TECWERK Tool Holder for Boring Bars — VDI30, E2 S, 32 mm Clamping

The TECWERK tool holder for boring bars (Form E2 S, Type B) provides a slotted, wrap‑around clamping solution for turning and boring applications, engineered to improve stability and tool life.

• VDI30 interface for secure mounting
• Slotted E2 S design reduces vibration
• Clamping diameter 32 mm for boring bars
• External and internal cooling compatible

Stable clamping for improved surface finish and tool life

The slotted, wrap‑around design delivers a secure grip on round shanks and is especially effective for full‑round boring bars with a V‑groove. By mechanically damping oscillation through the slotted design, the holder reduces vibration, which directly improves surface finish and extends cutter life. The VDI30 interface ensures a repeatable, concentric connection to the turret or spindle, so run‑out is controlled and setup time is minimised. This combination supports higher process stability and fewer scrapped parts.

Clear dimensional compatibility for seamless integration

Designed to the DIN 69880 standard, the holder matches common machine interfaces and bar sizes. Key dimensions include clamping diameter 32 mm, overall length 142 mm, working length 120 mm, outer diameter 62 mm, and shank diameter 30 mm; the unit conforms to Form E2 S and is specified as Type B. These measurable values allow straightforward verification against machine tool envelopes and existing tooling, reducing the effort required for retrofits and ensuring correct selection for the intended boring bar geometry.

Operational considerations and safety features that matter on the shop floor

This variant is specified as Type B (not through‑drilled), so internal coolant delivery through the shank is not available on this exact model; external coolant remains compatible. The holder is secured with a retaining ring to prevent ejection in turret operations, supporting safe high‑speed use. The slotted gripping ranges are dimensioned to provide reliable clamping across bar diameters: up to 16 mm at 4×D, 20 and 25 mm at 3×D, and from 32 mm at 2.5×D. These design choices balance clamping force and flexibility, making the holder suitable for demanding industrial machining where predictable performance and operational safety are priorities.

FAQ

What size of boring bar does this holder accept?
The TECWERK tool holder accepts boring bars with a clamping diameter of 32 mm and is designed for full‑round bars including those with a V‑groove.

Is the holder compatible with machines using the VDI30 interface?
Yes, the holder uses the VDI30 interface and is compliant with DIN 69880, allowing direct mounting to compatible turrets and adapters.

Can coolant be fed through the holder?
This Type B variant is not through‑drilled, so internal coolant delivery through the shank is not available; external cooling remains possible.

How does the slotted design affect performance?
The slotted, wrap‑around design reduces vibration and improves grip on round shanks, which leads to better surface finish and extended tool life.

Is the holder secure for turret operations?
Yes, the holder is secured with a retaining ring to prevent ejection during indexing or high‑speed turret cycles.
