Ingersoll Cutting Tools 6118287 Carbide Turning Insert

Product Description

The INGERSOLL CUTTING TOOLS 6118287 is a CNMG332EM TT5080 solid carbide turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. It features an 80-degree diamond insert shape with a neutral hand orientation and a negative rake geometry. The TT5080 grade substrate is coated with AlTiN and TiN via a PVD process, delivering heat resistance and edge durability during demanding cuts. The corner radius measures 0.0312 inches and the maximum depth of cut is 0.1180 inches. Licensed machinists and CNC turning specialists install this insert in toolholder pockets designed for the CNMG style.

This insert is engineered for use on stainless steel, super-alloys, and titanium workpieces, corresponding to ISO material group codes M and S. It is well-suited for finish and semi-finish turning passes where edge retention and surface integrity are critical. The EM chip breaker geometry is optimized for these difficult-to-machine materials, helping manage chip flow and reduce built-up edge at the cutting zone. Typical applications include aerospace component turning, medical implant finishing, and industrial pump or valve body machining where tight tolerances and difficult materials are standard.

Key Features

• TT5080 solid carbide grade with AlTiN and TiN PVD coating for extended tool life on hard and abrasive materials
• 80-degree diamond insert shape (CNMG style) with negative rake and 0 degrees relief angle for rigid, stable cutting
• EM chip breaker geometry designed for stainless steel, super-alloys, and titanium (ISO M and S material groups)
• Corner radius of 0.0312 inches supports controlled surface finish on finish and semi-finish turning passes
• 4 usable cutting edges per insert maximizes value per unit
• Clamp-style insert holding method compatible with standard CNMG toolholder pockets

Compatibility

Designed as an OEM-style replacement or direct drop-in for CNMG332EM turning insert applications. ANSI code CNMG332EMTT5080 and ISO code CNMG090408EM TT5080 govern toolholder and pocket compatibility. Verify that the target toolholder accepts a CNMG insert style with a 0.375-inch inscribed circle and clamp-style retention before installation.

Installation Notes

This insert is installed by a qualified machinist or CNC tooling technician. Before changing inserts, confirm the machine spindle is stopped and all motion has ceased per standard lockout procedure. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamp; do not over-torque the clamp screw. Index or replace the insert when visible wear, chipping, or surface finish degradation is observed on the workpiece.
