Hertel 2SHVNGA332630BN Pcbn Turning Insert 3/8 in Ic

Product Description

The HERTEL 2SHVNGA332630BN is a polycrystalline cubic boron nitride (PCBN) turning insert designed for precision machining of hardened steels, cast irons, and other difficult-to-cut materials. It carries manufacturer grade HT630BN and is supplied uncoated, making it suitable for applications where coating adhesion or thermal properties of PCBN alone meet the cutting requirement. The insert features a 35-degree diamond shape (V), a 3/8-inch inscribed circle, and a 1/32-inch corner radius, which together define its cutting geometry and edge engagement. This insert is installed by machinists and toolroom professionals on CNC lathes and turning centers running hard-turning or finishing operations.

This insert is intended for use in turning applications where tight tolerances and fine surface finishes are required on hardened workpieces. The 2SH-VNGA insert style, combined with a neutral relief angle (clearance code N) and tolerance code G, positions it for high-precision finishing passes. The chip breaker designation A and clamp-plus-pin holding method are standard for rigid, secure seating in compatible toolholders. It is commonly used in production and job-shop environments on CNC turning equipment handling hardened ferrous materials.

Key Features

• Polycrystalline cubic boron nitride (PCBN) insert material for hard-turning applications
• HT630BN manufacturer grade, uncoated, for direct PCBN cutting performance
• 35-degree diamond insert shape (shape code V) for low cutting forces on slender or precision workpieces
• 3/8-inch inscribed circle with 1/32-inch corner radius for controlled edge geometry
• Clamp and pin holding method for secure, repeatable insert seating
• Material grade C2 with tolerance code G for consistent dimensional accuracy

Compatibility

Designed for use in 2SH-VNGA style turning toolholders that accept inserts with a 3/8-inch inscribed circle, 3/16-inch insert thickness, and a 0.150-inch hole diameter with clamp-and-pin holding. Verify toolholder specifications against insert size code 332 before installation.

Installation Notes

Insert installation should be performed by a qualified machinist following the toolholder manufacturer's clamping torque and seating procedures. Power down and lock out the machine before changing inserts. Inspect the toolholder pocket and locating pin for wear or debris before seating the insert. PCBN inserts are brittle and should not be dropped or subjected to impact during handling.
