Hertel 2SHDNGA432630BN Turning Insert Pcbn Diamond

Product Description

The HERTEL 2SHDNGA432630BN is a single-point turning insert manufactured from Polycrystalline Cubic Boron Nitride (PCBN), an uncoated superhard cutting material suited for high-speed finishing and semi-finishing of hardened ferrous materials. The insert follows a diamond (D) shape with a 55-degree included angle, a 1/2-inch inscribed circle, and a 3/16-inch thickness. Corner radius measures 1/32 inch (0.0313 inch decimal). Manufactured to grade HT630BN with a G tolerance and N clearance code, this insert delivers tight dimensional consistency required for precision turning applications on CNC lathes and turning centers.

This insert is designed for machining hardened steels, hard cast irons, and similar difficult-to-cut ferrous alloys where conventional carbide tooling reaches its limits. The DNGA-style insert seats in a clamp-and-pin style toolholder and carries a chip breaker code of A. It is appropriate for production turning environments including automotive component machining, bearing surface finishing, and other applications requiring consistent surface finish on hardened workpieces. Insert size code is 432 and material grade is C2.

Key Features

• Polycrystalline Cubic Boron Nitride (PCBN) insert material - uncoated, for hardened ferrous machining
• Diamond insert shape (D), 55-degree included angle for versatile profiling and turning
• 1/2-inch inscribed circle with 3/16-inch insert thickness for robust edge support
• 1/32-inch corner radius (0.0313 inch) for controlled surface finish and edge integrity
• G tolerance and N clearance code for precise seating in compatible toolholders
• Clamp and pin holding method (DNGA style) for secure, repeatable insert positioning

Compatibility

Designed as an OEM-style replacement or direct-fit insert for DNGA-style toolholders accepting a 1/2-inch inscribed circle, 3/16-inch thick diamond insert with a clamp-and-pin holding method.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing any turning insert. Use the appropriate torx or hex key per the toolholder manufacturer specification to secure the clamp - do not overtighten by hand estimation alone. PCBN inserts are brittle relative to carbide; avoid impact loading and interrupted cuts unless the grade is specifically rated for interrupted-cut service.
