54mm Tool Holder For Boring Bars E2 S Slotted, 20mm Bore, DIN 69880 - TECWERK
The slotted Form E2 S design combines targeted vibration reduction with a secure retaining-ring lock, delivering steady cutting performance in VDI30 setups; order the holder directly via Metav Werkzeuge or consult the technical team for integration advice. TECWERK Tool Holder VDI30 — 20 mm Clamp, Form E2 S (Type B) The TECWERK tool holder is a slotted Form E2 S clamping solution for 20 mm boring bars, engineered to reduce vibration and ensure repeatable alignment in turret-mounted turning work Slotted design reduces vibration Compatible with VDI30 taper Secured by retaining ring against falling out External and internal coolant options Greater process stability through controlled clamping The slotted construction and wrap-style clamping yield vibration reduction that translates directly into improved surface finish and longer insert life. By accommodating a 20 mm clamping diameter in a compact assembly, the holder stabilises the boring bar and reduces chatter during interrupted cuts. This controlled clamping behaviour supports consistent part quality and fewer reworks on small to medium-batch production runs. Coolant-ready and adaptable for different bar types Designed for both external and internal coolant, the holder supports effective chip control and tool cooling, which helps maintain cutting edge condition and process reliability. The slotted jaw accepts full-round boring bars with a V‑groove as well as slotted bar types, allowing quick integration into existing bar tooling systems. The retaining ring prevents the holder from falling out of the turret, adding a further layer of operational safety. Precise interface and repeatable positioning The VDI30 interface gives a VDI30-standard connection that simplifies replacement and indexing on compatible turrets. Key dimensions—54 mm outer diameter, overall length 95 mm and shank diameter 30 mm—provide a compact footprint while maintaining the axial and radial stability required for fine boring operations. Accurate mechanical interfacing reduces setup time and supports repeatability across tool changes. Clear limitations and practical maintenance notes The product is delivered as Type B, which is not through-drilled; while many holders are through-drilled where feasible, this variant does not allow length adjustment from the shank side. The slotted section geometry is engineered to specific engagement depths and ratios to control clamping force; the assembly remains serviceable with standard turret maintenance and benefits from routine inspection of the securing ring for wear and correct seating.
