MATERIALS
Recommended Materials
Thanks to its thicker 4mm cutting core, the R104 handles higher lateral forces without breaking, rendering it optimal for dense, abrasive, or prone-to-melt materials: 
Acrylic / Plexiglass (PMMA)
Aluminum Composite Panels (Dibond / ACM)
Expanded PVC Waveboard & Forex
Solid Polycarbonate & Engineering Plastics 

Operational Advantages
Optimized Chip Evacuation: The single O-flute upward spiral geometry creates a spacious channel that aggressively ejects waste upward and away from the cut path.
Thermal Regulation: Rapid debris clearing prevents the friction-induced heat that commonly causes plastics to melt back together or gum up the tool bit.
Superior Edge Finish: The rigid 4.0 mm geometry eliminates tool deflection, resulting in smooth, post-process free, and burr-free perpendicular edges.
