Value Collection 112369736 TPG322 TCN55 Carbide Turning Insert

Product Description

The VALUE COLLECTION 112369736 is a solid carbide turning insert designed for metal cutting on CNC lathes and manual turning centers. It carries the ANSI insert code TPG322 and manufacturer grade TCN55, with a CVD-applied TiC and TiN coating for wear resistance and extended tool life. The triangular insert geometry features a 60-degree included angle, a 3/8-inch inscribed circle, a 1/32-inch corner radius, and a positive side clearance. At 1/8 inch thick and 16.5 mm long, it fits standard TPG-style toolholders using a clamp holding method. Tolerance code G and clearance code P define its dimensional class. This insert is suited for steel and stainless steel turning applications across a range of material grades.

This insert is intended for use in turning operations on ferrous workpiece materials, including steels and stainless steels, as indicated by primary workpiece material codes M and P. It is appropriate for light to medium roughing and finishing passes where a flat-top chip breaker geometry performs well. Licensed machinists, toolroom operators, and CNC turning specialists working in production or job-shop environments are the typical end users. The flat-top chip breaker design handles a wide range of chip control scenarios without a molded groove geometry.

Key Features

• CVD-coated with TiC and TiN layers for improved hardness and heat resistance
• 60-degree triangular insert shape (Insert Shape Code T) with 11-degree relief angle
• 3/8-inch (0.3750 inch) inscribed circle for rigid engagement in TPG toolholders
• 1/32-inch (0.0313 inch) corner radius suitable for general turning profiles
• Positive side clearance reduces cutting forces on ferrous workpiece materials
• Clamp-style holding method compatible with standard TPG insert seats

Compatibility

Designed as an OEM-style replacement or direct-fit insert for TPG-style turning toolholders accepting ANSI size code 322 inserts. ISO insert code TPG160308 (Iso Code TPGN160308) applies for cross-referencing to metric toolholder systems. Material grades C5, C6, and C7 are associated with this insert.

Installation Notes

This insert is installed and indexed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torque wrench and insert clamp screw specified by the toolholder manufacturer to secure the insert. Inspect the insert seat and clamp for debris or damage before each installation to ensure proper seating and tool life.
