OF-2525 1/4" O-Flute End Mill

1/4" O-Flute End Mill
Tungsten Carbide • Nano Blue Coated

Overview
Built for clean, efficient cutting in plastics and softer non-ferrous materials. The single-flute O-flute geometry clears chips well, helps reduce heat buildup, and supports higher feed rates for cleaner edges and less melting.

Best For

• Acrylic and other plastics
• HDPE, UHMW, and Delrin
• PVC
• Soft aluminum with light cuts

Why Choose It

• Single flute for strong chip evacuation
• Helps reduce heat in plastics
• Supports higher feed rates
• Produces clean edges with minimal melting

Starting Parameters
Best results come from moderate RPM and higher feed rates. Adjust for material, rigidity, and chip formation.

• Spindle: 16,000–22,000 RPM
• Feed: 180–350 IPM
• Plunge: 40–80 IPM
• Cut Strategy: Keep feed high enough to form chips, not melt material
