The SCGCR ISO cartridges are designed for internal turning, boring and finishing or semi-finishing operations on CNC lathes, conventional lathes and modular tooling systems. The 90° tool angle and seat for CCMT 1204 inserts allow internal machining with good control of the profile, wall and bottom surface, while maintaining cutting stability and dimensional accuracy. The cartridge holds the insert in a defined and repeatable position, making cutting-edge replacement easier and reducing machine downtime during production.

These cartridges are suitable for machining internal diameters, shoulders, cylindrical surfaces, internal faces and profiles where controlled accessibility is required. The CCMT 1204 insert, with its positive rhombic geometry, supports smooth and controlled cutting action, helping reduce machining forces and improve surface finish on steels, stainless steels, cast irons, light alloys and technical materials depending on the insert grade selected. The 90° angle is especially useful when internal shoulders, perpendicular surfaces and machining close to walls or bottoms must be controlled.

The correct cartridge must be selected according to the minimum machinable diameter, body section, useful length, clamping rigidity and available space inside the workpiece. Correct sizing helps reduce vibration, deflection, dimensional errors and surface defects, especially in internal machining where overhang and tool rigidity are critical factors.

For best performance, a rigid clamping system should be used, with correct tightening of both cartridge and insert. Alignment with the machining axis must be checked, and cutting parameters must be selected according to material, depth of cut, feed rate and insert nose radius. Inadequate clamping or excessive tool overhang can generate vibration, irregular insert wear, poor surface finish and loss of geometric accuracy. These ISO cartridges are suitable for mechanical workshops, CNC departments, toolrooms, industrial maintenance, automotive applications and precision metalworking where reliable modular tools are required for internal machining with widely available ISO inserts.
