Insert mounting system - "S" - that is, for Torx screw. It is a boring bar with an angle of 60 degrees.

Most external turning knives, positive or negative geometry boring knives. Single-sided indexable inserts mounted on the surface of the tapered-arc bore with a countersunk screw. The "S" system is the most common system of fixing indexable inserts. It is characterized by simplicity, high reliability, very good repeatability of the blade position and the ability to mount inserts of small dimensions. The main area of application of knives with inserts clamped in the "S" system is finishing of external surfaces and surfaces of holes (especially holes with small diameters), but they are also used for roughing.
