Kennametal 1866677 Turning Insert VBGT2205LF KC5025 Carbide

Product Description

The KENNAMETAL 1866677 is a solid carbide turning insert with ANSI designation VBGT2205LF and ISO designation VBGT110302, finished with a PVD-applied TiAlN coating and manufactured to grade KC5025. The insert features a 35-degree diamond (rhombic) shape, a neutral hand orientation, and a screw-on holding method. With an inscribed circle of 0.25 inches, an insert length of 0.8718 inches, and a corner radius of 0.0079 inches, this insert is engineered for finishing and light machining operations. The LF chip breaker geometry promotes controlled chip evacuation at light depths of cut up to 0.0492 inches. Licensed machinists and CNC turning specialists install this insert in compatible tool holders for precision turning, facing, boring, back turning, and back boring applications.

This insert is suited for finishing and light machining of stainless steel, superalloys, titanium, steel, cast iron, aluminum, and other non-ferrous materials, covering workpiece material codes P, M, K, N, and S. The KC5025 grade delivers moderate wear resistance and toughness across these material groups, making it a versatile choice for job shops and production turning cells running a range of workpiece materials. It is sold individually per package, with a minimum order quantity of 5 pieces.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine before changing inserts. Seat the insert fully into the pocket and tighten the clamping screw to the tool holder manufacturer's specified torque using the appropriate Torx or hex key. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper contact and runout.
