•EFFECTIVE DIAMETER FOR RPM CALCULATIONDx
Due to the small size of these inserts, it is vital that you only use a pre-set torque screw drivereff
(0.4Nm) at all times for assembly and adjustment.When calculating revolution per minute (n), the effective diameter must be taken into l
•account. Refer to the formula below.D=D1 +

It is also recommended that during mounting, the insert should be held in place with your finger. eff

  • When using the cutter for the first time, the following start procedure should be followed. This procedure needs to be done only once, the first time the milling cutter perform the first touch on
