Value Collection 112370136 TPG431 Carbide Turning Insert

Product Description

The VALUE COLLECTION 112370136 is a solid carbide turning insert designed for general-purpose lathe and CNC turning operations. Manufactured to ANSI grade TPG431 and ISO grade TPG220404, this insert carries a CVD-applied TiC and TiN coating under manufacturer grade TCN55, providing wear resistance and extended tool life in steel and stainless steel applications. The triangular insert geometry features a 60-degree included angle, an 11-degree relief angle, a 1/2-inch inscribed circle, and a 1/64-inch corner radius. At 3/16 inch thick and 22 millimeters in length, it fits standard TPG-style toolholders with clamp-style insert retention. Machinists and CNC operators in production and job-shop environments are the primary users.

This insert is suited for turning operations on workpiece material codes M and P, covering carbon steels, alloy steels, and stainless steels. The flat-top chip breaker geometry and positive side clearance promote efficient chip flow and reduced cutting forces in both roughing and finishing passes. Material grade compatibility spans C5, C6, and C7 carbide classifications, making it a versatile option across a range of cutting conditions and feed rates.

Key Features

• Solid carbide substrate with CVD TiC and TiN coating for wear and heat resistance
• ANSI insert code TPG431, ISO insert code TPG220404 for direct toolholder compatibility lookup
• 60-degree triangular shape with 11-degree positive relief angle reduces cutting forces
• 1/2-inch inscribed circle and 3/16-inch insert thickness for stable seating in TPG toolholders
• 1/64-inch corner radius suitable for general finishing and semi-roughing operations
• Clamp-style holding method compatible with standard TPG insert seats

Compatibility

Designed as an OEM-style replacement for TPG431-style solid carbide turning inserts used in clamp-style TPG toolholders rated for C5, C6, and C7 carbide grade applications.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the insert pocket and clamp are clean and free of chips before seating to prevent rocking or improper contact. Inspect the clamp screw and toolholder seat for wear each time an insert is indexed or replaced.
