3 Flute Single End 45° Helix Corner Radius Center Cutting Alu-Mill TC Carbide End Mill

Three flute Triple Crown carbide end mills for aluminum are designed for maximum chip evacuation and extended tool life.   The square end combined with three flutes insure accurate location when slotting. A higher helix angle shears the material for greater tool life. A blended radius is ground during manufacture to insure a consistent blend of the cutting edge. 

  • High velocity milling of aluminum and other non-ferrous materials
  • 3-flute and 45° helix allow harmonic balance at high-speed conditions and smooth cutting
  • Tightly controlled and improved surface roughness-cylindrical margin
  • Maximum metal removal rate
  • Superior chip evacuation
  • Blended radius reduces wear and improves workpiece finishes
