Value Collection 112369609 TPG321 Carbide Turning Insert

Product Description

The VALUE COLLECTION 112369609 is a solid carbide turning insert designed for precision metal-cutting operations on CNC and manual lathes. Following the TPG321 ANSI standard, this insert features a triangular 60-degree included angle, a 3/8 inch inscribed circle, and a 1/64 inch corner radius. The manufacturer grade I22 carbide substrate is suited for finishing and semi-finishing passes. The flat-top chip breaker geometry and positive side clearance promote clean chip evacuation and reduce cutting forces. A licensed machinist or CNC operator installs this insert in compatible TPG-style toolholders as part of a standard turning setup.

This insert is appropriate for use in both manual and CNC turning centers where a TPG-style triangular insert is specified. The positive clearance geometry and carbide material make it a practical choice for cutting cast iron, non-ferrous metals, high-temperature alloys, and stainless steel, corresponding to ISO workpiece material codes K, M, N, and S. Material grades C5 and C6 indicate suitability across a range of finishing and light-to-moderate cutting conditions. The clamp-style insert holding method allows for repeatable indexing and secure seating in production environments.

Key Features

• ANSI insert code TPG321 with ISO equivalent TPG160304
• Solid carbide construction, manufacturer grade I22
• 60-degree triangular insert shape with three usable cutting edges
• Positive side clearance (clearance code P) reduces cutting resistance
• Flat-top chip breaker geometry for controlled chip flow
• Clamp-style holding method for secure, repeatable indexing

Compatibility

Designed as a standard TPG-style replacement turning insert for use in clamp-type toolholders accepting a TPG321 triangular insert with a 3/8 inch inscribed circle. ISO equivalent code is TPGN160304.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or indexing the insert. Use the appropriate clamp screw and torque it to the toolholder manufacturer's specification. Inspect the insert seat and clamp for wear or debris before installation to ensure proper support and seating of the cutting edge.
