Smaller Cutting Chip
• The center and peripheral inserts are positioned in order to divide the cutting chips into smaller spiral shape. It helps the cutting chip to be removed faster and easier.
• Designed for high productivity, high speed cutting. Coolant supply is needed.

Better Surface Finish and Better Diameter Accuracy
• Special insert positioning to balance the cutting forces, better surface finish and diameter accuracy are achievable.

Cutting Insert

  • Fully ground dual-relief insert, for improved surface finish and higher feed rate.
  • Primary relief angle is to increase the toughness of the insert, secondary relief angle is to strengthen the axial feed rate.
  • Same insert for outer and inner insert.
  • Square insert with 4 cutting edges, reducing cost per insert.
  • Better surface finish.
  • Better diameter accuracy.
