Request A Quote
The Zund R203 5209419 Solid Carbide Multipurpose Router Bit is a single-edged spiral end mill designed for compatible Zünd digital cutting and CNC routing systems. Featuring a 3mm cutting diameter, 6mm shank and 11mm maximum routing depth, it is suitable for precision machining of various rigid and flexible sheet materials.
Zund R203 5209419 Solid Carbide Multipurpose Spiral Router Bit
Specifications
Item Number / Part No.: 5209419 (Standard) / 5211435 (R203-A variant with stop ring)
Shank Diameter: 6 mm
Routing / Tip Diameter: 3 mm
Max Routing / Cutting Depth: 11 mm
Total Length: 58 mm (or 50–58 mm depending on variant)
Design / Geometry: Single-flute, up-cut spiral (right-hand spiral) for fast chip ejection
Max Rotation Speed: 50,000 RPM
Geometry & Performance Benefits
Up-Cut Design: The right-hand spiral forces chips upward out of the channel, preventing clogging and reducing heat buildup during high-speed operation.
Single O-Flute: Features a polished, wide flute valley optimized for fast chip evacuation, which is critical when machining melting-prone plastics or soft aluminum.
End Mill Profile: Engineered with flat bottom-cutting capabilities, producing highly precise square corners and a perfectly smooth finish on the bottom surface of partial cuts.
Core Variations
Zund R203 (Part #5209419): The standard version without a stop ring, loaded manually into basic routing spindles.
Zund R203-A (Part #5211435): Includes an integrated stop ring. This variant is mandatory for machines equipped with an Automatic Router bit Changer (ARC) system to ensure automatic initialization and depth calibration.
Recommended Applications & Materials
Classified as a "multipurpose" bit, the R203 balances structural rigidity and fine-cutting capabilities across soft, fibrous, and semi-rigid materials:
Plastics: Acrylic (PMMA), Polycarbonate, Expanded PVC (Forex/Sintra), Polypropylene, and PETG.
Composites: Aluminum Composite Materials (ACM, Dibond, Alupanel).
Wood & Foams: MDF, Plywood, Sign Foam (HDPU), and hard paperboards.
Metals: Soft aluminum alloys (frequently paired with Minimum Quantity Lubrication or mist systems).
