Kennametal 1866675 Turning Insert VBGT22X0LF KC5025

Product Description

The KENNAMETAL 1866675 is a solid carbide turning insert designated VBGT22X0LF in the KC5025 grade, designed for precision metal cutting in CNC and manual turning operations. Featuring a 35-degree diamond (rhombic) insert shape and a PVD-applied TiAlN coating, this insert delivers moderate wear resistance and toughness across a wide range of workpiece materials. The neutral hand orientation and screw-on holding method make it a versatile choice for shops running high-precision finishing and light machining passes. The honed cutting edge and positive rake geometry help reduce cutting forces on thin-walled or difficult-to-machine components.

This insert is suited for finishing and light machining applications including turning, facing, boring, back turning, and back boring. Its primary workpiece material targets are stainless steel and superalloys and titanium, with additional capability across steel, cast iron, and aluminum and non-ferrous materials. The 0.0492-inch maximum depth of cut makes this insert best matched to light stock-removal passes rather than heavy roughing work. It is typically used in toolholders that accept screw-clamped VBGT-style inserts in CNC turning centers and manual lathes.

Key Features

• KC5025 grade with PVD TiAlN coating for moderate wear resistance and toughness in P, M, K, N, and S material classes
• 35-degree diamond insert shape (VBGT) with positive rake and positive side clearance for reduced cutting forces
• LF chip breaker geometry optimized for finishing and light machining passes
• Honed cutting edge style for improved edge stability on difficult-to-machine materials including superalloys and titanium
• Screw-on insert holding method for secure, repeatable seating in compatible toolholders
• Two cutting edges per insert for extended tool life per unit

Compatibility

Designed as an OEM-style replacement for VBGT22X0LF screw-on turning insert toolholders conforming to ANSI and ISO standards. ISO insert code VBGT1103003. ANSI size code 22X0.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and de-energize the machine spindle before changing inserts. Seat the insert fully in the pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate torx or hex key. Inspect the insert pocket for chips or debris before seating to ensure proper contact and runout accuracy.
