Value Collection TCN21035J Turning Insert TPGH322 TCN55

Product Description

The VALUE COLLECTION TCN21035J is a solid carbide turning insert with a TiN (titanium nitride) coating, designed for use in CNC and manual turning operations. It carries the ANSI insert code TPGH322 and ISO insert code TPGH160308. The insert has a triangular shape with a 60-degree included angle, a 3/8-inch inscribed circle, a 1/8-inch thickness, and a 1/32-inch corner radius. The positive side clearance and screw-holding method make it a standard fit for external turning and profiling applications. Machinists and tool-and-die professionals install and index these inserts as part of regular production operations.

This insert is suited for turning steel and stainless steel workpiece materials, consistent with the primary workpiece material codes M and P. The TPGH insert style with positive relief angle is commonly used in medium-finish turning passes where controlled chip flow and edge sharpness are priorities. The H chip breaker geometry assists in managing chip evacuation during continuous cuts. These inserts are sold individually but carry a minimum order quantity of 10 units per order.

Key Features

• Solid carbide construction with TiN coating for improved wear resistance and edge life
• 60-degree triangular insert shape (ANSI style TPGH322) provides multiple usable cutting edges
• 1/32-inch corner radius for medium-finish turning applications
• Positive side clearance with 11-degree relief angle reduces cutting forces
• Screw-mounted insert holding method for secure, repeatable indexing
• H chip breaker geometry aids chip control in continuous turning operations

Compatibility

Designed as a standard TPGH322-style turning insert compatible with tool holders specifying ANSI insert code TPGH322 and ISO insert code TPGH160308 with a 0.177-inch hole diameter screw-lock seat.

Installation Notes

Turning insert installation and indexing should be performed by qualified machinists with the machine powered down and spindle locked. Use the appropriate torx or hex key as specified by the tool holder manufacturer to secure the clamping screw to the correct seating torque. Inspect the insert pocket and shim seat for debris or damage before seating a new insert. Follow all applicable shop safety procedures when handling carbide inserts, as edges are extremely sharp.
