The inserts in these holders have a positive insert back, which enables sharper insert geometries and thus the possibility of achieving a better surface quality. Holders of type "P", "M", "T", "C" and "D" with clamping per inch or clamp are suitable for common to roughing operations - they have higher rigidity.
