Hertel 8852050 Turning Insert TPG321T00320 HT601CA Ceramic

Product Description

The HERTEL 8852050 is a ceramic uncoated turning insert designed for precision metal-cutting operations on CNC lathes and manual turning centers. Manufactured to the TPG321T00320 style designation with a grade of HT601CA, this insert features a 60-degree triangular shape with a neutral hand orientation. The inscribed circle measures 0.375 inches, the insert length is 0.63 inches, and the corner radius is 0.0156 inches (1/64 inch). The ceramic substrate provides high heat resistance and wear performance in hard-turning and high-speed finishing applications. Licensed machinists and CNC operators install this insert as a direct replacement in compatible toolholders.

This insert is suited for hard turning, interrupted cuts in hardened steels, and high-speed finishing passes where ceramic grades outperform carbide. The neutral hand orientation makes it adaptable to both right-hand and left-hand toolholder setups. The TPG clamp-style holding method and P clearance code with G tolerance code ensure consistent seating and dimensional repeatability in production environments. Typical applications include shaft turning, facing, and light profiling on ferrous materials.

Key Features

• TPG321T00320 style with 60-degree triangular shape and positive rake geometry
• Neutral hand orientation fits right-hand and left-hand toolholders
• 0.0156-inch corner radius for fine finishing passes
• Clamp-style holding method (TPG) with P clearance and G tolerance codes
• Insert thickness of 0.125 inches for rigid seating in standard TPG pockets

Compatibility

Designed for use in standard TPG-style toolholders accepting a 3/8-inch inscribed circle, 60-degree triangular insert with a P clearance code and G tolerance designation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and in a locked-out state. Ensure the toolholder pocket is clean and free of debris before seating the insert. Tighten the clamp screw to the toolholder manufacturer's specified torque using the correct torque key. Ceramic inserts are brittle and should not be subjected to heavy interrupted cuts or conditions outside the grade's recommended parameters.
