Ingersoll Cutting Tools 6188597 Turning Insert CNMG432MGP

Product Description

The INGERSOLL CUTTING TOOLS 6188597 is a CNMG432MGP turning insert in grade TT8125B, designed for negative-rake external turning operations on steel workpieces. The insert is manufactured from solid carbide and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides a hard wear-resistant interface at the cutting edge. The 80-degree diamond (C) shape delivers strong edge geometry suited to general turning and light profiling. With a 0.5 inch inscribed circle and a 0.031 inch corner radius, this insert fits standard CNMG toolholders and is clamped in place during operation. Licensed machinists and CNC turning technicians are the primary installers.

This insert is used in production and job-shop turning applications where the primary workpiece material is steel. The MGP chip breaker geometry is suited to medium-depth passes, with a maximum depth of cut of 0.197 inches. The neutral hand designation means the insert performs equally in conventional right-hand and specific left-hand toolholder setups without an inherent directional bias. It is appropriate for both CNC lathes and manual turning centers where a clamped CNMG-style insert is specified. Each package contains one insert, and the minimum order quantity is 10 pieces.

Key Features

• Solid carbide substrate with CVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on steel
• 80-degree diamond insert shape (ANSI code CNMG432MGPTT8125B) for strong nose strength and versatile turning geometry
• MGP chip breaker designed for medium-depth turning passes on steel
• 4 cutting edges per insert, maximizing cost-per-edge value
• Neutral hand orientation compatible with standard CNMG clamped toolholders
• Maximum depth of cut of 0.197 inches suits general-purpose roughing and semi-finishing passes

Compatibility

Designed for use in standard CNMG clamped turning toolholders with a 0.5 inch inscribed circle pocket. Primary workpiece material compatibility is steel (ISO material code P). ISO designation CNMG120408MGP TT8125B may be used to cross-reference compatible toolholder systems.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or indexing the insert. Verify the toolholder pocket and clamp are clean and free of debris before seating the insert to ensure proper contact and clamping force. Always index or replace worn edges before the insert reaches a failure condition to protect the workpiece and toolholder pocket.
