48mm Cross Slot Arbor With 22mm Collet For Cutter Heads, DIN 69871 AD/B - TECWERK

Take advantage of the combination of an enlarged flange diameter, central coolant supply and a steep DIN taper for consistent clamping and efficient cooling during heavy milling. Order this specialised arbor through Metav Werkzeuge or request technical advice from our consultants for an optimal integration into production.

Side-groove mounting arbor DIN 69871 Form AD/B – SK40, 22 mm clamping diameter (TECWERK)

The Side-groove mounting arbor DIN 69871 AD/B is a CNC tool-holder designed for secure reception of cutter heads and milling cutters with side grooves, delivering controlled coolant flow and robust clamping for industrial machining

• Central coolant supply for optimal cooling
• Resealable coolant channels at the flange
• DIN 69871 Form AD/B steep taper
• SK40 shank, 22 mm clamping diameter

Improved tool life through controlled coolant delivery

The arbor places coolant exactly where it matters: a central coolant supply combined with resealable coolant channels at the flange and additional coolant holes at the face directs lubricant and coolant into the cutting zone. This targeted supply reduces thermal load and chip welding, which in turn lowers wear on inserts and cutter bodies. For production settings where cycle-time consistency and insert life have direct cost implications, the improved cooling capability translates into fewer tool changes and steadier process results. The component’s fluid-routing is designed to be simple to refill and maintain without compromising the sealing at the flange.

Stable clamping and repeatable concentricity for precise milling

The steep taper according to DIN 69871 Form AD/B and the enlarged flange diameter provide a robust interface between spindle and tooling, improving axial and radial rigidity during side-groove milling. The SK40 shank with a 22 mm clamping diameter offers a widely adopted interface for medium to heavy-duty milling spindles, making the arbor suitable for toolrooms and industrial workshops. Enhanced flange geometry reduces runout and vibration, which supports consistent surface finish and tighter dimensional tolerances when paired with cutter heads conforming to DIN 1880.

Workshop-ready dimensions and compatibility for easy integration

Designed for practical integration, the arbor’s key dimensions are supplied to align with standard tooling inventories: A = 100 mm, D = 48 mm, Clamping Ø = 22 mm, L1 = 19 mm. These dimensions permit quick selection against existing cutter heads and enable predictable tool offsets in CAM settings. The unit is intended for capturing cutter heads and milling cutters with side grooves per DIN 1880, so compatibility checks are straightforward. For complex setups or verification of suitability for a specific machine spindle, Metav’s technical team is available to provide clarification and measurement support.

FAQ

What taper standard does the arbor use?
The arbor uses the steep taper specified by DIN 69871 Form AD/B, ensuring compatibility with spindles and holders designed to that standard.

Which clamping diameter and shank does it have?
The tool-holder features a 22 mm clamping diameter and an SK40 shank, making it suitable for many medium-duty milling spindles.

How does the coolant routing work on this arbor?
Coolant is supplied centrally and distributed via resealable channels at the flange plus additional coolant holes at the face, directing fluid to the cutting zone for improved cooling and chip evacuation.

Which cutter heads are compatible with this arbor?
The arbor is designed for reception of cutter heads and milling cutters with side grooves according to DIN 1880; compatibility should be checked against the cutter head’s nominal groove specification.
