Value Collection 112369636 TPG321 Turning Insert Carbide

Product Description

The VALUE COLLECTION 112369636 is a solid carbide turning insert designed for use in CNC and manual turning operations on metalworking lathes. Manufactured to ANSI insert code TPG321 and ISO insert code TPG160304, this insert features a triangular shape with a 60-degree included angle, an 11-degree relief angle, and a positive side clearance geometry. The insert is CVD-coated with TiC and TiN layers under the manufacturer grade TCN55, providing wear resistance and extended tool life during interrupted and continuous turning cuts. It measures 16.5 mm in length with a 3/8-inch inscribed circle and a 1/64-inch corner radius. Installation is handled by machinists, tool and die setters, and CNC operators in machine shops and production environments.

This insert is suited for turning ferrous and non-ferrous workpiece materials corresponding to ISO material codes M and P, which include general-purpose steels and stainless steels. The flat-top chip breaker geometry and clamp holding method make it appropriate for finish and semi-finish turning passes where consistent surface finish and dimensional control are required. It fits standard TPG-style toolholders configured for clamp-style insert retention.

Key Features

• ANSI code TPG321, ISO code TPG160304 for straightforward toolholder matching
• CVD-applied TiC and TiN coating under grade TCN55 for wear resistance
• 60-degree triangular insert shape with positive side clearance for reduced cutting forces
• 1/64-inch corner radius suitable for finish turning applications
• Flat-top chip breaker with clamp holding method for secure seating in TPG toolholders
• Compatible with ISO material groups M and P including general steels and stainless steels

Compatibility

Designed as an OEM-style replacement or direct-fit insert for standard TPG-style clamp toolholders accepting a 321 size code insert with a 3/8-inch inscribed circle.

Installation Notes

Turning inserts should be installed by qualified machinists or CNC operators. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer when securing the insert. Inspect the insert seat and clamp for debris or damage before seating a new insert to ensure proper clamping force and runout.
