Value Collection 112369309 TPG221 Carbide Turning Insert

Product Description

The VALUE COLLECTION 112369309 is a solid carbide turning insert designed for precision external and internal turning operations on CNC and manual lathes. Manufactured to ANSI code TPG221 and ISO code TPG110304, this triangular insert features an 11-degree relief angle, a 1/4-inch inscribed circle (0.2500 inches), and a 1/64-inch corner radius (0.0156 inches). The flat-top chip breaker geometry and positive side clearance make it well suited for finishing and light machining passes. Licensed machinists and tool-and-die technicians are the primary users. Each package contains one insert, with a minimum order quantity of 10.

This insert is appropriate for turning ferrous metals, non-ferrous alloys, and select superalloys as indicated by primary workpiece material codes K, M, N, and S. It fits triangular insert pockets using a clamp-style holding method, which is standard on a wide range of turning toolholders sized for TPG-style inserts. It is a practical choice for job shops and production environments where consistent geometry and repeatable surface finish are required.

Key Features

• Solid carbide construction, material grade C2, for wear resistance across a range of workpiece materials
• ANSI insert code TPG221 with matching ISO code TPG110304 for broad toolholder compatibility
• 60-degree included angle triangular shape provides three usable cutting edges per insert
• 11-degree relief angle with positive side clearance reduces cutting forces on finishing cuts
• Flat-top chip breaker geometry for predictable chip control without complex groove profiles
• 1/64-inch corner radius suitable for light finishing applications requiring controlled edge geometry

Compatibility

Designed as a direct-fit replacement for TPG221-style triangular turning insert pockets using clamp-style toolholders; confirm toolholder insert seat dimensions against ANSI TPG221 or ISO TPG110304 specifications before installation.

Installation Notes

Turning inserts of this type are installed and indexed by qualified machinists following standard toolholder manufacturer procedures. Power down and lock out the machine before seating or indexing the insert. Ensure the insert pocket and clamping components are clean and free of chips before installation. Follow the toolholder manufacturer torque guidelines for the clamping screw to avoid insert or seat damage.
