Iscar 5500614 Turning Insert Rcmt 10T3MO-14 IC20 Carbide

Product Description

The ISCAR 5500614 is a solid carbide, uncoated round turning insert in the RCMT 10T3MO-14 IC20 grade, belonging to the Isoturn series. It carries a 10 mm (0.3937 inches) inscribed circle, an insert thickness of 0.156 inches, and a maximum depth of cut of 5.00 mm (0.197 inches). The IC20 uncoated carbide substrate is suited for a wide range of workpiece materials and delivers consistent edge geometry across repeated indexing. This insert is installed and replaced by machinists and CNC turning specialists on production and job-shop lathes.

The RCMT 10T3MO-14 fits screw-held toolholders designed for round RCMT-style inserts. Its universal primary workpiece material classification covers cast iron, steel, stainless, non-ferrous, and high-temperature alloys, making it a general-purpose choice across diverse turning applications. The chip breaker designation 14 is optimized for facing operations. It is appropriate for both roughing and finishing passes within the rated depth-of-cut envelope on CNC and manual lathes in residential, commercial, and industrial machine shops.

Key Features

• Round RCMT insert shape with 10 mm inscribed circle for maximum edge count and re-indexability
• IC20 uncoated solid carbide grade suited for universal workpiece materials (ISO material groups H, K, M, N, S)
• 7-degree relief angle with clearance code C and tolerance code M for consistent dimensional accuracy
• Chip breaker 14 geometry designed for facing operations
• Maximum depth of cut of 5.00 mm (0.197 inches)
• Screw holding method for secure, repeatable insert clamping
• Conforms to ISO 13399 cutting tool data representation standards

Compatibility

Designed for use with screw-clamp toolholders accepting RCMT-style round inserts with a 10 mm inscribed circle and a hole diameter of 0.173 inches (4.39 mm). Compatible across multi-use applications including facing, as noted by the manufacturer. Verify toolholder seat geometry and screw size before installation.

Installation Notes

Insert replacement is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver or hex key specified by the toolholder manufacturer for the clamping screw — do not overtighten, as this can fracture the insert or damage the seat. Inspect the toolholder pocket and seating surface for chips or wear before seating a new insert.
