TECWERK Tool Holder for Boring Bars (VDI40) — E2 S, 25 mm Clamping, Type B

The TECWERK tool holder for boring bars is a VDI40 interface component designed for secure clamping of 25 mm boring bars in turning and milling turrets, engineered for reduced vibration and repeatable positioning.

• Form E2 S for stable clamping
• VDI40 interface, 25 mm clamping diameter
• Slotted design reduces machining vibration
• Secured in turret by a retaining ring

Stable clamping for precision boring and reduced vibration

This E2 S tool holder is engineered to combine mechanical rigidity with dynamic damping. The slotted design envelops the boring bar to reduce chatter and improve surface finish, while the VDI40 mounting provides a standardised interface for quick replacement. The result is consistent runout control and improved tool life compared with non‑slotted holders. For workshops that prioritise dimensional accuracy, this configuration decreases the need for rework and supports tighter tolerances on turned bores.

Versatile machining options with clear coolant guidance

The holder supports both standard external coolant arrangements; however, Type B variants are not through‑drilled, so internal through‑tool coolant is not available on this specific unit. The design remains suitable for solid round boring bars, including those with a V‑groove, and allows straightforward adoption of external coolant piping. This separation of coolant options helps to clarify setup choices during process planning and ensures that cooling strategy aligns with machine and bar specifications.

Compact dimensions and DIN‑standard fit for easy integration

Conforming to DIN 69880, the holder’s compact footprint and measured interface dimensions enable straightforward integration into existing VDI40 turrets. Key interface dimensions support reliable seating and retention: the outer diameter and shank proportions match common turret receptacles, and the retaining ring prevents accidental release into the turret. The E2 S form gives a balance between accessible tool overhang and secure contact area, supporting stable cutting conditions for precision boring tasks.

FAQ

Is this holder compatible with VDI40 turrets?

Yes. The TECWERK tool holder is designed for the VDI40 interface and fits standard VDI40 turret receptacles (SKU 2000833490NW).

Can internal coolant be used with this Type B holder?

No. This Type B variant is not through‑drilled, so internal through‑tool coolant is not available; external cooling is possible.

What clamping diameter is provided?

The holder provides a 25 mm clamping bore (d2) suitable for corresponding boring bars.

Does the slotted design really reduce vibration?

Yes. The slotted, wrapping geometry is intended to reduce vibration and increase stability compared with non‑slotted clamping, improving surface finish.

How is the holder secured in the turret?

The holder is retained by a retaining ring to prevent accidental release into the turret during operation.
