Sandvik Coromant 7860535 Turning Insert VNMG332-LC 4415

Product Description

The SANDVIK COROMANT 7860535 is a VNMG-style solid carbide turning insert in grade 4415, designed for precision metal turning operations on CNC lathes and turning centers. This insert features a CVD-applied multilayer coating of Al2O3, TiN, and TiCN for extended tool life and thermal resistance when cutting steel. The 35-degree diamond shape (V-shape insert code) with a neutral hand orientation provides versatile approach angles. With a 3/8-inch inscribed circle and a 0.0313-inch corner radius, this insert is engineered for medium to finishing turning passes where dimensional accuracy and surface finish quality are critical. Installation requires no specialized skills beyond standard insert indexing procedure.

This insert is intended for steel workpiece materials (ISO material group P) and fits into compatible VNMG toolholders using clamp or screw holding methods. It is suited for use on CNC turning equipment in production machine shops, toolrooms, and manufacturing environments where consistent chip control is required. The LC chip breaker geometry is optimized for light to medium cutting depths on ferrous materials. This insert carries ISO designation VNMG 16 04 08-LC 4415 and belongs to the SANDVIK COROMANT T-Max P series.

Key Features

• CVD-coated with Al2O3, TiN, and TiCN multilayer coating for heat and wear resistance
• 35-degree diamond insert shape with neutral hand for flexible toolholder compatibility
• LC chip breaker geometry designed for controlled chip formation in steel turning
• 4 available cutting edges per insert for cost-effective tooling utilization
• Clamp and screw holding compatibility with standard VNMG toolholders
• Grade 4415 carbide substrate suited for ISO P (steel) workpiece materials

Compatibility

This insert uses ISO designation VNMG 16 04 08-LC 4415 and is compatible with toolholders designed to accept VNMG-style inserts with clamp or screw holding. It is intended for primary use on steel workpiece materials per ISO material group P classification within the T-Max P series system.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or toolroom technician with the machine fully stopped and locked out per applicable safety procedures. Use the correct torque wrench and insert seat screw as specified by the toolholder manufacturer when securing with screw-lock holders. Inspect the insert pocket and seating surface for chips or debris before indexing to a fresh cutting edge. Confirm tool offset compensation after any insert change to maintain part tolerances.
