Cross-slot mounting milling arbour (DIN 69871 AD/B) — SK40, 16 mm clamping Ø, TECWERK

The cross-slot mounting milling arbour is a SK40 taper accessory for the secure installation of cutter heads and slot cutters to DIN 1880, designed for machining tasks that demand rigid clamping and effective coolant delivery.

• Enlarged collar diameter for greater stability
• Central coolant supply with resealable channels
• Steep taper to DIN 69871 Form AD/B

Engineered for secure clamping and consistent concentricity

The arbour is built around a steep taper (DIN 69871 AD/B) and a SK40 seating to provide a rigid spindle-to-tool connection that reduces vibration and runout. With a 16 mm clamping Ø, the design supports precise retention of cutters and heads with a cross slot to DIN 1880, so concentricity and repeatable positioning are achieved across batch production. The enlarged collar diameter increases bearing surface and resists bending moments, which translates into improved surface finishes and reduced rework in demanding milling operations.

Optimised coolant routing for improved tool life and process stability

Integrated central coolant supply and resealable coolant channels at the collar, together with additional coolant bores on the face, enable targeted delivery of cutting fluid to the tool interface. This configuration aids in effective chip removal and thermal control, which in turn lowers cutting temperatures and extends cutter life. The possibility to close channels at the collar gives flexibility in different machining setups, while the radial and face coolant exits promote consistent lubrication and reduce the risk of clogging during interrupted cuts.

Practical compatibility and workshop benefits

Designed to receive cutter heads and slot cutters to DIN 1880, the arbour supports straightforward integration into existing tool sets and changeover processes. The combination of standardised taper, clear dimensional data and active coolant features reduces setup time and simplifies inventory management for production and jobbing shops. Conformity to recognised standards provides an additional layer of reliability for quality assurance procedures, while the robust mechanical design contributes to predictable process outcomes and lower overall operating costs.

FAQ

What cutters are compatible with this arbour? The arbour accepts cutter heads and slot cutters designed with a cross slot to DIN 1880; compatibility is ensured when the cutter conforms to that standard.

How is coolant supplied to the tool? Coolant is delivered via a central supply through the taper with resealable channels at the collar and additional bores on the face to direct fluid to the cutting zone.

What taper and shank does the arbour use? The product uses a DIN 69871 Form AD/B steep taper with a SK40 shank for machine spindle mounting (SKU 2000833815NW).

Why choose an enlarged collar diameter? An enlarged collar diameter increases bearing surface and resistance to bending, improving stability and concentricity during heavy or interrupted milling.

Can coolant channels be closed for dry machining? Yes, the collar channels are designed to be resealable, providing flexibility to run with or without internal coolant routing.
