- Use the specified set bolt when using the arbor type with internal coolant supply. (1) using insert radius 0,8 mm Note: During helical interpolation do not exceed maximum pitch. When using different insert radius to calculate the ØDHmin and ØDHmax use the equation below: - Minimum Diameter: ØDHmin = 2 x (ØDc - (R corner radius + F width of edge wiper) - Maximum Diameter: ØDHmax = 2 x (ØDc - R corner radius)
