Kennametal 1785714 Turning Insert VBGT332HP KC5010 Carbide

Product Description

The KENNAMETAL 1785714 is a solid carbide turning insert in the VBGT332HP geometry, coated with TiAlN via a PVD process and graded KC5010. It carries a 35-degree diamond (rhombic) shape with a 5-degree relief angle, a 3/8-inch inscribed circle, and a 1/32-inch corner radius. The HP chip breaker is configured for finishing operations, delivering a positive rake angle of 15 degrees and a honed cutting edge for clean, controlled cuts. With two usable cutting edges and a screw-on holding method, this insert is suited for high-wear-resistance applications across steel, stainless steel, and cast iron workpieces. Machinists and CNC turning specialists working in production or job-shop environments will find it a direct fit for demanding finishing passes.

This insert is designed for turning, facing, boring, back turning, and back boring operations. Its KC5010 grade targets steel (P), stainless steel (M), cast iron (K), and superalloys and titanium (S and N codes), covering a broad range of primary workpiece materials. The positive side clearance and high wear-resistance characteristics make it well suited for finishing passes at tighter tolerances where surface finish and tool life consistency are the priority. It conforms to both ANSI and ISO standards, with the ANSI insert code VBGT332 and the ISO insert code VBGT160408, making it easy to cross-reference against toolholder catalogs.

Key Features

• 35-degree diamond (rhombic) insert shape for access in tight-clearance turning setups
• TiAlN PVD coating on a solid carbide substrate for high wear resistance across steel, stainless, and cast iron
• HP chip breaker geometry optimized for finishing operations with a 15-degree positive rake angle
• Screw-on holding method with a 0.1732-inch hole diameter for secure, repeatable seating in compatible toolholders
• Two cutting edges per insert, maximizing value per unit
• Conforms to ANSI and ISO standards for broad toolholder compatibility

Compatibility

Designed for use in screw-on style VBGT toolholders conforming to ANSI and ISO standards for 35-degree diamond inserts with a 3/8-inch inscribed circle. Suitable for multi-use turning applications including turning, facing, boring, back turning, and back boring on steel, stainless steel, cast iron, superalloys, and titanium workpieces.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or swapping inserts. Use the appropriate torx or hex key to snug the clamping screw to the toolholder manufacturer's specified seating torque — do not overtighten, as this can fracture the carbide substrate. Inspect the insert pocket and clamping screw for debris or wear before each insert change.
