Key Specifications and Models:
Zund R43
Shank diameter: 3 mm
Routing diameter: 3 mm
Max. routing depth: 11 mm
Max RPM: 80,000
Material compatibility: Plastics (PC, PMMA/Acrylic)
Zund R71/R72
Shank diameter: 3 mm
Routing diameter: from 2 mm up to 5 mm (depending on the specific bit)
Spiral (usually right-hand/upcut) design
Single cutting edge (O-flute)
oUsage: Suitable for plastics, ACM, PVC, and similar panel materials
Zund R75
Specific details for R75 are less commonly listed. R75 falls within the solid carbide spiral router bit family and should have similar compatibility and geometry (single O-flute, spiral design, 3 mm shank).
Material Construction & Features:
Manufactured from solid carbide or fine grain tungsten carbide, ensuring durability and extended tool life.
O-flute geometry optimizes chip evacuation and provides a polished edge, especially for plastics and composites.
Bits are often rainbow/DLC coated for premium wear resistance, especially for ACM and metals.
Compatible Use Cases:
Zund router bits are engineered for use in Zund digital cutters (G3, L3, S3, D3, ARC systems) and are appropriate for applications including precision routing, contouring, pocketing, and engraving on acrylic, polycarbonate, plastic, aluminum composite, PVC, polypropylene, MDF, and more.
The exact model choice (R43, R71, R72, R75) is determined by:
Material thickness and composition
Desired edge quality and routing depth
Machine holder and auto tool changer compatibility
Typical Sourcing & Equivalents:
Multiple suppliers offer direct replacements and equivalents for Zund R-series bits, including Shenzhen Oyea Machinery Co., Ltd., and others. Equivalent bits are often referenced by Zund OEM part numbers or cross-listed with Esko, Colex, Gerber, and Summa system compatibility.
Notable Options:
Coated bits (e.g., rainbow, DLC coatings) provide extended tool life for demanding materials or high-volume cutting.
Stop ring variants are available for use with Zund's ARC/Auto Tool Changer systems.
Selection & Application Recommendations:
For thin plastics and acrylic: R43 and R71 provide clean, precise cuts at very high speeds.
For thicker or tougher materials (ACM, PVC, aluminum): use coated R72, R75, or equivalent bits, possibly with specialized coatings.
Always match the bit diameter and shank to your material thickness, routing profile, and machine compatibility.
Consider auto tool changer compatibility if running high-throughput production.
When selecting among Zund R-series carbide router bits, focus on matching shank size, flute style, and coating to your most common materials. For heavy-duty or high-volume jobs, coated bits and stop ring designs offer better longevity and consistent changeover with Zund auto tool systems.
