48mm Cross-Slot Arbor With 22mm Clamping Diameter, DIN 69871 AD/B With Central Coolant - TECWERK

Benefit from the combination of an enlarged collar diameter, a steep DIN 69871 AD/B taper and a central coolant supply with resealable channels for stable, coolant‑optimised cross‑slot milling. Order the arbor directly via Metav Werkzeuge or request advice from our consultants.

Cross‑slot milling arbor — DIN 69871 Form AD/B, SK40, Ø48 mm, clamping Ø22 mm (TECWERK)

Cross‑slot milling arbor (Quernutaufsteckfräsdorn) delivers rigid holding for cutter heads and milling cutters with DIN 1880 cross‑slots, suited to productive metalworking environments

• Steep taper DIN 69871 AD/B for secure seating
• Central coolant supply with resealable channels
• Enlarged collar for improved rigidity and stability
• Compatible with SK40 holders, clamping Ø 22 mm

Increased rigidity for precise machining outcomes

The arbor is engineered to improve the stability of mounted cutter heads: the enlarged collar diameter raises the contact area and reduces vibration during heavy cuts, which directly supports more consistent surface finishes and predictable tool life. By combining a robust external geometry with the standardised DIN 69871 Form AD/B taper, the holder ensures repeatable axial seating in SK40 spindles and minimises runout-related rejects. This stability benefits batch production and one‑off operations alike by reducing rework and downtime.

Reliable coolant delivery for longer tool life

Integrated central coolant supply and resealable coolant channels at the collar, plus additional coolant holes at the face, provide direct fluid delivery to the cutting interface. Improved coolant flow helps evacuate chips and control cutting temperatures, which extends the service life of cutters and reduces the frequency of tool changes. For users who value uptime, the optimised coolant routing offers a measurable improvement in process reliability without requiring modifications to existing coolant systems.

Conforms to standards and eases tool planning

Designed to the DIN 69871 AD/B standard and compatible with cutter heads to DIN 1880, this arbor simplifies procurement and tool presetting. The standard taper form makes the arbor interchangeable in conventional SK40 toolholders, so workshop planners can standardise tooling arrays and minimise inventory complexity. Clear, measurable specifications such as Ø 48 mm body diameter, clamping diameter 22 mm and A = 35 mm support accurate fixture design and NC programme validation.

Practical benefits for everyday workshop use

Installation and maintenance are straightforward: the arbor accepts cutter heads and milling cutters with DIN cross‑slots and the resealable channels reduce contamination risk when the tool is idle. The combination of a precise taper, enlarged collar and direct coolant feed translates into fewer stoppages for tool‑related issues and a steadier production flow. For machinists and purchasing managers seeking a durable, standards‑based solution, this toolholder provides a clear balance of performance and compatibility.

FAQ

What spindle taper does this arbor use?
The arbor uses the DIN 69871 Form AD/B taper and is designed for SK40 spindles, ensuring secure seating and repeatable positioning.

Which cutter heads can be mounted to this arbor?
Cutter heads and milling cutters with a DIN 1880 cross‑slot fit the arbor; the design supports direct mounting and stable clamping for indexable and solid cutter systems.

How does the coolant supply improve performance?
The central coolant feed with resealable channels and additional face holes delivers coolant directly to the cutting zone, improving chip evacuation and reducing cutting temperatures for extended tool life.

Is the clamping diameter specified?
Yes — the arbor provides a clamping diameter of 22 mm, which is indicated for the compatible tool shanks or collets.
