Value Collection ICC21025D Turning Insert TPGH321 Grade I55

Product Description

The VALUE COLLECTION ICC21025D is a solid carbide turning insert designed for precision lathe and turning center operations. Manufactured to the ANSI insert code TPGH321 and ISO insert code TPGH160304, this uncoated bright-finish insert features a triangular shape with a 60-degree included angle and a positive side clearance geometry. The inscribed circle measures 3/8 inches (0.375 inches) and the corner radius is 1/64 inches (0.0156 inches). Manufactured in carbide material grade C5/C6, it is suitable for general-purpose turning applications requiring sharp, consistent cutting edges. Installed by machinists and CNC operators in production and job-shop environments.

This insert is applied in external and internal turning operations on lathes and turning centers. The TPGH style with positive clearance and screw-holding method suits light to medium cuts where tight tolerances and clean surface finishes are required. The H-style chip breaker assists in chip control during continuous turning passes. Primary workpiece material code P indicates suitability for steel and ferrous materials. Sold individually with a minimum order quantity of 10 units, this insert is a stock replacement for toolholders accepting TPGH321-style inserts.
