Value Collection 112076506 Turning Insert TPU321 I55

Product Description

The VALUE COLLECTION 112076506 is a solid carbide turning insert designed for use in CNC and manual lathe operations. Manufactured to ANSI insert code TPU321 and ISO insert code TPU160304, this triangular insert features a 60-degree included angle, a 3/8-inch inscribed circle, and a 1/64-inch corner radius. The I55 manufacturer grade and C5/C6 material grade classification make it suitable for steel and ferrous metal cutting applications. A positive side clearance and 11-degree relief angle reduce cutting forces and extend tool life in precision turning work. Licensed machinists and CNC operators install this insert as part of standard tooling setups on indexable turning toolholders.

This insert is intended for use in turning applications involving primary workpiece materials classified under ISO material group P, which covers carbon steels, alloy steels, and ferritic stainless steels. The flat-top chip breaker geometry and clamp-style holding method suit production environments where consistent chip control and secure insert retention are required. It is sold individually with a minimum order quantity of 10 units, making it appropriate for both shop restocking and production-scale tooling programs.

Key Features

• Solid carbide construction in material grade C5/C6 for hardness and wear resistance in steel cutting
• 60-degree triangular insert shape (ANSI code TPU321, ISO code TPU160304) with three usable cutting edges
• 1/64-inch corner radius for general-purpose turning with controlled surface finish
• Positive side clearance and 11-degree relief angle to reduce cutting force and tool pressure
• Flat-top chip breaker (code N) for predictable chip formation on ferrous workpieces
• Clamp-style insert holding method compatible with standard TPU-style indexable toolholders

Compatibility

Designed for use in indexable turning toolholders that accept ANSI TPU321 or ISO TPMN160304 style inserts with a clamp-style holding method and positive clearance geometry.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer when seating the insert — do not overtighten by hand. Inspect the insert seat and clamp for debris or damage before each installation to ensure proper insert support and cutting accuracy.
