EATS HARD METAL.

Use 4 Flute X-Series Tools when:

• Removing material left from drills
• Helical Boring
• Corner Processing
• Making heavier cuts with more surface contact
• 25% X,Y step-over
• 200 SFM 15 ipm average.

Use XF 6, 8, or 10 flutes:

• High speed finishing cuts
• Strong cutting edges
• Superior finishes
• Various corner radii as standard
• 2% to 10% X,Y step-over
• Faster speeds and feeds
  • Titanium 400 SFM
  • 45-75 ipm

Machining tips:

• Use High Pressure Coolant:
  • Helps avoid chip packing
  • Controls heat
  • Eliminates thermal shock
• Avoid too many flutes in heavy cuts
• Control heat by reducing width of cut
  • 100% width = 180-degree cut = 50% time in the cut
  • 50% width = 90-degree cut = 25% time in the cut
  • 25% width = 60-degree cut = 17% time in the cut
• Trochoidal machining techniques
  • Slotting that acts like profiling
  • Great for high temp alloys
    • Hard metal machining
    • Titanium
    • Nickel Alloys
  • Tool diameters of 50% to 62% of slot width
  • Depth of cut (Z) = 1.5 to 2 x tool diameter
  • Width (X,Y Step) = 3 to 10%
