Value Collection TCN12130J TPG320 Turning Insert Tin Carbide

Product Description

The VALUE COLLECTION TCN12130J is a solid carbide turning insert with a titanium nitride (TiN) coating, designed for use in external and internal turning operations on CNC lathes and manual turning centers. Manufactured to the TPG320 ANSI insert standard and TPG160301 ISO standard, this insert features a 60-degree triangular shape with an 11-degree relief angle, a 0.375 inch inscribed circle, and a 0.004 inch corner radius. The flat-top chip breaker geometry and positive side clearance make it suited for finishing and light roughing cuts. Licensed machinists and CNC operators are the primary installers and users of this consumable tooling insert.

This insert is intended for turning applications where a TPG-style, top-clamp held triangular insert is required. The TiN coating improves wear resistance and extends tool life when cutting steel and stainless steel workpiece materials, consistent with its primary workpiece material codes of M and P. The C5 material grade designation indicates suitability for general-purpose turning of steel alloys. It fits any toolholder designed to accept TPG320 inserts with clamp-style insert retention.

Key Features

• Solid carbide substrate with TiN coating for extended wear resistance
• TPG320 ANSI and TPG160301 ISO compliant geometry
• 60-degree triangle shape with positive side clearance and 11-degree relief angle
• 0.004 inch corner radius for controlled surface finish
• Flat-top chip breaker for predictable chip control in steel turning
• Clamp-style insert retention compatible with standard TPG toolholders

Compatibility

Designed as a direct-fit replacement for TPG320 insert positions in clamp-style turning toolholders accepting a 60-degree triangular insert with a 0.375 inch inscribed circle and G-tolerance fit.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before seating or replacing the insert. Ensure the toolholder pocket and clamp are clean and free of chips before inserting. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten the clamp screw, as carbide inserts are brittle and can fracture under excessive clamping force.
