Value Collection 112369509 TPG320 Carbide Turning Insert

Product Description

The VALUE COLLECTION 112369509 is a solid carbide turning insert designed for precision metal cutting on CNC and manual lathes. Manufactured to the TPG320 ANSI insert code and ISO designation TPG160301, it features a triangular insert shape with a 60-degree included angle, an 11-degree relief angle, and a positive side clearance geometry. The inscribed circle measures 0.375 inches, insert thickness is 0.125 inches, and the corner radius is 0.004 inches. Insert length is 16.5 mm. The I22 manufacturer grade designates a solid carbide substrate suited for a range of workpiece materials. Licensed machinists, CNC programmers, and toolroom technicians are the primary users.

This turning insert is suited for finishing and light roughing operations on cast iron, non-ferrous metals, stainless steel, and heat-resistant alloys, corresponding to ISO workpiece material groups K, M, N, and S. The flat-top chip breaker geometry makes it appropriate for controlled chip formation in these applications. It seats into standard TPG-style toolholders that use a clamp holding method, making it a direct fit for common external turning and boring setups in job shop and production environments.

Key Features

• Solid carbide construction with I22 grade designation for consistent hardness and wear resistance
• TPG320 ANSI insert code with ISO equivalent TPG160301 for broad toolholder compatibility
• 60-degree triangular insert shape provides three usable cutting edges per insert
• Positive side clearance and 11-degree relief angle reduce cutting forces on workpiece
• Flat-top chip breaker for predictable chip control across multiple material groups
• 0.004 inch corner radius suited for finishing passes requiring tight surface finish tolerances

Compatibility

Designed as an OEM-style replacement or direct-use insert for standard TPG-style clamp-type toolholders accepting a 3/8 inch inscribed circle, 60-degree triangular carbide insert with positive clearance geometry.

Installation Notes

This insert is installed and replaced by machinists or toolroom technicians using appropriate insert-seating tools and torque wrenches per toolholder manufacturer specifications. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Inspect the insert pocket and clamp for wear or damage before seating a new insert. Follow the toolholder manufacturer guidelines for clamp screw torque to avoid insert fracture or improper seating.
