Sandvik Coromant 7860486 Turning Insert Coroturn 107

Product Description

The SANDVIK COROMANT 7860486 is a TCMT-style turning insert from the CoroTurn 107 series, designed for external turning operations on CNC lathes and turning centers. It features a triangular insert shape with a 60-degree included angle, a 1/4-inch inscribed circle, and a 1/32-inch corner radius. The substrate is solid carbide with a CVD-applied multilayer coating of Al2O3, TiCN, and TiN, giving it strong wear resistance and thermal stability at elevated cutting speeds. The UF chip breaker geometry is optimized for finishing passes. This insert is installed by machinists and CNC operators in production and job-shop environments.

This insert is suited for finishing and light turning applications in both production and job-shop settings. Its primary workpiece material is steel, with a secondary rating for cast iron. The UF chip breaker promotes controlled chip formation at lighter depths of cut and feed rates typical of finishing work. Holding methods include clamp and screw, consistent with standard TCMT toolholder systems. The neutral hand configuration makes it compatible with both right- and left-hand turning approaches depending on toolholder orientation.

Key Features

• CVD multilayer coating: Al2O3, TiCN, and TiN for wear and thermal resistance
• UF chip breaker geometry optimized for steel finishing operations
• Triangular 60-degree insert shape with 3 usable cutting edges
• 1/32-inch corner radius for tight-tolerance finishing passes
• Neutral hand insert fits a wide range of TCMT-compatible toolholders
• ISO code TCMT 11 02 08-UF 4415 for cross-reference ordering

Compatibility

Designed for use in TCMT-compatible toolholders within the Sandvik Coromant CoroTurn 107 system. Fits toolholders accepting clamp or screw insert retention. ISO standard reference is TCMT 11 02 08-UF 4415. Industry standard number matches the same designation for cross-brand toolholder reference.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque wrench and insert screw to secure the insert per the toolholder manufacturer specification. Inspect the insert pocket and seating surface for chips or contamination before installation to ensure proper seating and dimensional accuracy.
