The insert features a 35-degree diamond (rhombic) shape, a positive rake geometry, a 5-degree relief angle, and a honed cutting edge style. At 16.61 mm in length with a 3\/8-inch inscribed circle and a 1\/64-inch corner radius, this insert is designed for finishing and light machining operations. It provides moderate wear resistance and toughness across steel, stainless steel, cast iron, and non-ferrous workpiece materials, with primary suitability for stainless steel and superalloys.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in turning, facing, boring, back turning, and back boring applications on CNC lathes and manual turning centers in industrial machining environments. The LF chip breaker geometry targets finishing and light-stock-removal passes where tight tolerances and surface finish quality are priorities. The KC5025 grade is well suited to stainless steel and superalloy components where controlled cutting forces and edge stability matter. Installation requires a screw-on insert holding method compatible with VBGT-style toolholders. The neutral hand orientation makes it adaptable to both right-hand and left-hand toolholder setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e35-degree diamond (rhombic) insert shape for profiling and contour turning in tight clearance situations\u003c\/li\u003e\n\u003cli\u003eKC5025 grade with PVD TiAlN coating delivers moderate wear resistance and toughness for steel, stainless steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eLF chip breaker optimized for finishing and light machining operations\u003c\/li\u003e\n\u003cli\u003ePositive rake, 5-degree relief angle with honed cutting edge for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert; screw-on mounting method for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO insert standards; multi-use across turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in VBGT-style screw-on toolholders compatible with ANSI insert code VBGT331 and ISO insert code VBGT160404.
