TECWERK side‑slot arbour DIN 69871 AD/B — SK40, central coolant

TECWERK side‑slot arbour engineered for mounting cross‑slot cutter heads and milling cutters on SK40 spindles in CNC and toolroom applications.

• DIN 69871 Form AD/B SK40 taper
• Central coolant feed and face outlets
• Resealable coolant channels at collar
• For DIN 1880 cross‑slot cutter heads

Accurate taper and repeatable seating for reliable production

The DIN 69871 Form AD/B taper, realised in a standard SK40 shank, provides a rigid mechanical interface that reduces runout and enhances repeatability during prolonged series work. By focusing on a mechanically stable connection, the arbour minimises vibration and tool deflection, which translates into improved surface finish and consistent part tolerances. Such stability is particularly relevant for precision milling tasks in medium‑volume production where fixture reliability directly affects throughput and scrap rates.

Integrated coolant routing to protect tools and increase uptime

Equipped with a central coolant supply, resealable coolant channels at the collar and additional outlet holes at the face, the arbor ensures targeted coolant delivery to the cutting zone. This configuration promotes effective chip evacuation and thermal management, lowering the risk of workpiece distortion and premature tool wear. The ability to seal and re‑open collar channels allows for flexible maintenance without dismantling the machine, enhancing operational availability and reducing unplanned downtime.

Direct compatibility and practical workshop fitment

Designed for the reception of cutter heads and milling cutters with a cross‑slot to DIN 1880, the arbour matches common tooling standards while offering clear dimensional data: D 58 mm, clamping diameter 27 mm, A 40 mm and L1 21 mm. These measurements facilitate straightforward integration into existing tool sets and adapters for SK40 spindles. The enlarged collar diameter improves flange contact and concentricity, making the component suitable for toolrooms and production shops seeking both adaptability and robust performance.
