44mm Tool Holder For Boring Bars E2 S Slotted, Through‑Bored DIN 69880, 95mm - TECWERK

Take advantage of the combination of a VDI30 taper, a through-drilled coolant path and a slotted vibration-damping design for reliable, precise boring operations; order the holder via Metav Werkzeuge or consult the specialists for application advice.

Tool holder for boring bars E2 S (DIN 69880) — VDI30, 10 mm clamping

The Tool holder for boring bars E2 S is a VDI30-compatible, through-drilled holder designed for stable, coolant-capable boring and secure retention in turret applications.

• VDI30 taper with 10 mm clamping diameter
• Through-drilled for internal and external coolant
• Slotted design reduces vibration for stable cuts
• Secured with retention ring against falling out

Stable mounting for consistent bore quality

A VDI30 interface combined with a 10 mm clamping bore delivers a compact, repeatable mounting solution that reduces axial and radial runout for improved precision. The unit’s 44 mm diameter and its optimised geometry increase stiffness at the cutting point, which directly benefits dimensional accuracy and surface finish. Where concentricity matters, the design limits wobble and maintains shorter cycle rework rates while supporting standard boring-bar formats.

Coolant-ready layout for better tool life and finish

The through-drilled construction provides a continuous channel for both coolant delivery and chip evacuation, enabling internal or external supply depending on the machining setup. Direct coolant supply to the cutting edge reduces temperatures and extends insert life, while also improving surface quality and minimising built-up edge. For processes that demand reliable cooling under higher material removal or interrupted cuts, this feature contributes to consistent results and longer service intervals.

Vibration damping and secure retention for uninterrupted cycles

The slotted execution wraps around the boring bar to reduce vibration and dampen resonances during cutting, which lowers the risk of chatter and extends tool life. The holder accepts full-round boring bars with a V-groove and includes a retention ring to prevent the assembly from falling out of the turret, improving operational stability during revolver indexing or heavy cuts. This combination of clamping and damping helps maintain tool geometry and cycle reliability in repetitive production.

Standard conformity and workshop-friendly setup

Compliant with DIN 69880 and manufactured to Form E2 S, the holder matches common turret interfaces and mounting routines, simplifying integration into existing tool inventories. With an overall length of 95 mm and an effective length L1: 73 mm, the component allows straightforward positioning and repeatable set-up, while length adjustment from the shank side is supported when the shank is through-drilled. The standardised design reduces setup time and supports centralised tool management for smoother workflow.
