Zund R72 Multipurpose Milling & Router Bits Type 3910753

Key Specifications

Part Number: 3910753
Material: Solid tungsten carbide
Flutes: 1 flute (single-edged)
Cut Angle: Up-cut
Shank Diameter: 3 mm
Routing / Cutting Diameter: 2 mm
Max Routing Depth: 6 mm
Total Length: ~30 mm to 38 mm
Max Rotation Speed: Up to 80,000 RPM
Compatible Tools/Modules: Zünd Universal Routing Tool (URT) and Router Modules (such as RM-A 150W / 450W)

Recommended Materials
True to its multipurpose designation, the R72 excels across soft metals, rigid sheets, and natural composites:
Aluminium Composite Materials (ACM / Dibond / Maxmetal)
Rigid & Semi-Rigid Sheet Plastics (Acrylic, Polypropylene, PE, PET, PETG, Polycarbonate)
Signage Foams (Expanded PVC / Forex / Sintra)
Wood Composites (MDF, Plywood, Hardwoods)

System Integration & Compatibility
The R72 interfaces natively with Zünd's routing hardware, working with the Universal Routing Tool (URT), Router Module RM-A (150W / 450W), and RM-L configurations. It is fully compatible with Zund G3, S3, L3, and D3 digital cutters and is supported inside the Zund Cut Center (ZCC) software framework.

Key Differences to Keep in Mind
Total Length (30mm vs 38mm): The Esko BIT-MUS03-2006-38 features a slightly longer total tool length of 38mm compared to the 30mm standard of the Zund R72/R41 bits. Ensure your Zund initialization sensor or Esko tool-head calibration accounts for this 8mm difference to prevent crashing the bit into your cutting mat.
Material Optimization: While the MUS series (Multi-purpose) is optimized to cut a broad range of materials like ACM, MDF, and Foams, the Esko AUS series is specially polished and ground to cut clean edges specifically in Acrylic and rigid plastics without melting.
