Radial tool holder B4 VDI40 (left, over-head) – TECWERK, DIN 69880, short

The Radial tool holder B4 VDI40 is a short, left-hand, over-head tool mount designed for standardised turret interfaces and radial machining in compact tool stations.

• Form B4, left-hand over-head design
• VDI40 interface for standard turrets
• External coolant delivery for improved tool life
• Short version for confined tool setups

Precision and compatibility for dependable machining

The holder is engineered around the VDI40 taper and the DIN 69880 standard, which together ensure repeatable seating and straightforward interchangeability across compatible turret systems. By adopting a standard interface and Form B4 geometry, the design reduces setup variability and supports consistent concentricity during radial operations. This repeatability contributes directly to predictable part tolerances and lower scrap rates, making the component suitable for production and repair environments that require reliable fixture behaviour.

Effective coolant delivery that supports longer tool life

An external coolant channel feeds directly to the cutting edge area, enabling targeted flushing of chips and improved heat dissipation. Focused coolant supply minimises thermal growth and helps maintain cutting-edge integrity, which in turn reduces wear and the frequency of tool changes. For operations where surface finish and tool longevity matter, the combination of directed cooling and secure tool mounting yields tangible efficiency gains and more stable cycle times.

Compact format for constrained tool stations

The short over-head design reduces overhang and increases rigidity compared with longer radial holders, aiding vibration suppression in tight setups. Reduced projection is particularly useful on multi-tool turrets or small lathes where clearance is limited; it permits more aggressive feeds without sacrificing stability. The compact form therefore supports higher effective cutting parameters on small to medium-sized workpieces while keeping the machine envelope optimised.

Robust mounting and straightforward integration

The component provides a secure interface for radial tooling with dimensions tailored for quick installation and dependable repeatability. Constructed to align with DIN 69880 specifications, the mount integrates into established tooling systems without the need for bespoke adapters. As a TECWERK product, it combines proven mechanical standards with practical design choices to simplify inventory and maintenance planning in production workshops.

FAQ

Is this holder compatible with all VDI40 turrets?
The Radial tool holder B4 VDI40 is designed to the VDI40 interface and DIN 69880 standard, so it fits turrets and adaptors that conform to those specifications.

What benefit does the external coolant provide?
External coolant delivery in this holder directs fluid to the cutting zone, improving chip evacuation and thermal control to extend tool life when using the Radial tool holder B4 VDI40.

Can the short over-head format be used on small lathes?
Yes; the short over-head design reduces overhang and increases rigidity, making it suitable for constrained tool stations and smaller turning centres.

Which mounting dimensions are critical for integration?
Critical measurements include the interface type VDI40 and the key geometry values listed in the technical data, which determine seating and clearance for the holder.
