Face clamping chuck DIN 69871 AD/B — Weldon drive, central coolant, SK40

The Face clamping chuck DIN 69871 AD/B is a SK40 taper tool holder designed for secure clamping of tools with a 10 mm shank and for use in machining centres that require DIN-standard tool interfaces.

• DIN 69871 AD/B compatibility
• Central coolant supply with re-sealable channels
• Weldon drive for secure lateral tool retention
• Suitable for 10 mm tool shank, SK40 taper

Reliable interface for uninterrupted machining

The holder provides a DIN 69871 interface with a steep taper to ensure repeatable seating and high concentricity. The combination of the SK40 taper and a Weldon lateral drive creates a robust mechanical connection that resists axial and radial forces during milling and drilling. The internal bore tolerance H4 guarantees tight concentricity for reduced run-out, which translates into longer tool life and improved surface finish. For production environments this means fewer stoppages and more consistent part quality, making the arbor an efficient choice for repetitive operations.

Targeted coolant delivery to extend tool life

Equipped with a central coolant supply and re-sealable coolant channels at the flange, the arbor directs cutting fluid precisely to the tool interface. Side coolant channels accommodate tools with a cylindrical shank and lateral drive according to DIN 1835-B, improving chip evacuation and thermal control at the cutting edge. The result is reduced heat-related wear and longer intervals between tool replacements, which lowers consumable costs and maintains cutting performance under prolonged cycles.

Compact dimensions for straightforward integration

The face clamping chuck features a flange diameter D: 35 mm and a projection A: 50 mm, with a clamping diameter of 10 mm and bore tolerance H4 for reliable tool retention. The compact geometry simplifies integration into existing SK40 spindles and keeps tool overhang to a minimum, helping to reduce vibration and improve accuracy. Manufactured to recognised standards, the holder is suited for workshops and production lines seeking a standardised, low-maintenance toolholding solution that supports predictable machining outcomes.
