Why Choose a Single Flute?

  • Large flute space helps evacuate chips from narrow cuts.
  • Lower tooth count provides more feed per tooth at common router spindle speeds.
  • Useful for routing sheet materials, profiles, slots and engraved features.
  • Solid carbide construction with multiple cutting diameters and lengths.

Machining Note

Chip evacuation is essential when routing acrylic and other heat-sensitive materials. Use suitable spindle speed, feed, air blast or chip extraction for the selected diameter and setup. Avoid recutting trapped chips.
