█ Precautionary Notes on Tool Selection · Select the largest shank size possible. █ Precautionary Notes on Tool Selection · Select the largest shank size possible. · It is recommended to mount the holder upside down. · Select a chipbreaker according to the cutting conditions.

· It is recommended to mount the holder upside down. · Select a chipbreaker according to the cutting conditions. · To ensure adequate chip evacuation, select the smallest corner radius possible unless restrictions apply. · To ensure rigidity as well, use a multi-function holder so long as the maximum groove depth can be achieved. · To ensure adequate chip evacuation, select the smallest corner radius possible unless restrictions apply. · To ensure rigidity as well, use a multi-function holder so long as the maximum groove depth can be achieved. 39
