General information on choosing a suitable holder:

Type "S" holders - with screw clamping are suitable for normal to finishing operations. They are suitable for smaller removals of material. The inserts for these holders have a positive back of the insert, which enables a sharper geometry of the inserts and thus the possibility of achieving a better surface quality.
P, "M" , "T" , "C" and "D" type holders with thumb or clamp are suitable for normal to roughing operations - they have higher rigidity. The inserts for these holders have a negative (straight) back of the insert, thanks to which the inserts do not break / deform so much and it is possible to rough with them and to machine better / longer even harder-to-machine materials.
