Zund R207-A 5212253 Tungsten Carbide Router Bit with Stop Ring

Key Specifications
Material/Type: Solid tungsten carbide, single-flute up-cut spiral router bit
Part / Article Number: 5212253 (Zünd)
Shank Diameter: 6 mm
Routing/Cutting Diameter: 2 mm
Cutting Edges / Flutes: 1
Total Length: ~58 mm to 60 mm
Max Rotation Speed: Up to 50,000 RPM
Special Feature: Pre-mounted pneumatic stop ring designed for use with Zünd’s Automatic Router bit Changer (ARC) systems
Performance & Mechanical Dynamics
The R207-A features a necked-down design where a small 2.0 mm cutting profile transitions to a thick 6.0 mm shank. This structural contrast provides a dual benefit: the heavy shank dampens high-frequency spindle vibrations to protect the fragile tip from snapping, while the polished single O-flute maximizes chip clearance. The aggressive up-cut action pulls hot debris and dust up out of the narrow 2mm channel, preventing friction, burrs, and material re-welding.
Primary Material Applications
While classified under the "multipurpose" family, the R207-A's small diameter and short 6mm reach make it perfect for tight-radius detailing, narrow grooving, and thin sheet profiling on dense materials:
Composites: Aluminum Composite Materials (ACM/Dibond).
Non-Ferrous Metals: Thin sheet aluminum, brass, and copper plates.
Plastics & Synthetics: High-detail Acrylic (PMMA), Polycarbonate, thin PETG, and Expanded PVC.
Hardware & Module Compatibility
This bit is fully integrated into the Zund Cut Center (ZCC) material database. Its stop ring allows the ARC pneumatic module to automatically pick, clamp, initialize, and clean the tool without manual operator intervention. It functions seamlessly across Zund routing hardware:
RM-A / RM-A QC (Standard & Quick-Change Router Modules)
RM-L (3.6 kW Heavy-Duty Router Module)
RM-S (High-Speed Router Module)
