S as in secure screw clamping
Simple clamping and still a secure connection
The centre screw ensures a secure connection of the insert with the tool holder.
Free chip evacuation
Thanks to the neutral insert position, the effectively available rake face angle is identical to the insert’s rake face angle. Because none of the clamping elements stick out, control of the chip evacuation is guaranteed.
The form lock screw guarantees a safe connection of the insert and the tool holder. Chip evacuation is not hindered by obstructive clamping elements. Due to the neutral insert position the effective rake angle is identical to that of the insert form and geometry.
