(1) Using insert radius 0,8 mm

(Note 3) Cutting conditions should be adjusted according to the machine and work rigidity.Note: During helical interpolation do not exceed maximum pitch
(Note 4) It’s possible to occur vibrations in certain cases. Please reduce depth of cut and / or reduce cutting conditions in following cases:When using different insert radius to calculate the ØDHmin and ØDHmax use the equation below:
- When using long shank;- Minimum Diameter: ØDHmin = 2 x (ØDc - (R corner radius + F width of edge wiper))
- When using long tool overhang with arbor type;- Maximum Diameter: ØDHmax = 2 x (ØDc - R corner radius)
