Walter 8116020 TNMG431-MP5 WPP10G Carbide Turning Insert

Product Description

The WALTER 8116020 is a TNMG431-MP5 WPP10G grade solid carbide turning insert designed for high-productivity CNC lathe operations. It features a CVD multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted cuts. The insert has a 60-degree triangular shape with a neutral hand orientation, a 0.016-inch corner radius, and a negative rake angle of 15 degrees. Six cutting edges are available per insert. This is a professional-grade cutting tool installed and indexed by machinists and CNC operators in production turning environments.

This insert is rated for primary use on steel workpieces (ISO material code P, material grade P10) and secondary use on cast iron (ISO material code K). The MP5 chip breaker geometry is suited for turning, facing, and boring operations across a length range of 0.700 to 10.000 inches depth of cut conditions. The insert meets both ANSI and ISO standards and carries the ISO designation TNMG220404-MP5 WPP10G, making it cross-referenceable in international tooling catalogs.

Key Features

• CVD multilayer coating (TiCN, Al2O3, TiN) for extended tool life on steel and cast iron
• 60-degree triangle insert shape with 6 available cutting edges per insert
• MP5 chip breaker geometry supports turning, facing, and boring applications
• Negative rake angle with chamfered and honed cutting edge for stable, controlled cuts
• Compatible with clamp and pin insert holding methods
• Meets ANSI and ISO standards; ISO code TNMG220404-MP5 WPP10G

Compatibility

This insert is designed for use in TNMG-style toolholders that accept a 1/2-inch inscribed circle, 3/16-inch thick triangular insert with clamp or pin holding. It is suited for steel and cast iron workpiece materials in CNC turning, facing, and boring setups.

Installation Notes

Installation and indexing should be performed by a qualified machinist or CNC operator with the machine powered down and spindle locked. Seat the insert fully against the toolholder pocket before engaging the clamp or pin. Inspect the cutting edge and pocket for chips or debris before indexing to a new edge. Follow the toolholder manufacturer's clamping torque specifications and applicable shop safety procedures.
