  • • Ability to handle high accuracy & large depth of cut applications.
    • - Run-out : within 0.05mm
    • - R accuracy : within 0.05mm
  • • Various diameters (Ø16,20,25,30,32,40,50)
  • • Minimal cutting resistance due to Helical cutting edge
  • • Anti-rotation of insert due to concave bottom & stable setting
        by flank support
  • • Long tool life & better processing due to 2 cutting inserts
  • • Better tool life with new grade
type Projection
  • • Various diameters (Ø16,20,25,30,32,40,50)
  • • Improved chip treatment with internal coolant
       (cutting edge portion)
  • • Long tool life & better processing
  • • Easy insert setting with projection part to
    prevent vibration during processing
