Built to the SumiNotch series standard, this insert features a TiAlN coating and a neutral hand orientation, making it suitable for a wide range of grooving and parting applications. The cutting width measures 0.125 inches with a maximum depth of cut of 0.150 inches, and a cutting height of 0.344 inches. The insert carries ANSI code SG-3125R and conforms to ISO 13399, giving tooling engineers a consistent data interface for tool management systems. Installation is handled by machinists and CNC setup technicians.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in applications requiring consistent, repeatable groove profiles across universal workpiece materials. The manufacturer grade EH520V with TiAlN finish supports cutting across material groups K, M, N, P, and S, covering cast iron, stainless steel, nonferrous metals, steel, and high-temperature alloys. The SumiNotch insert style fits compatible SumiNotch grooving toolholders and blade-style bodies designed for the SG-3125 insert seat. Typical applications include external grooving, facing grooves, and profile turning on production turning equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for flexible grooving setups\u003c\/li\u003e\n\u003cli\u003e0.125 inch cutting width with 0.150 inch maximum depth of cut\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.010 inches for controlled edge geometry\u003c\/li\u003e\n\u003cli\u003eCompatible with universal workpiece material groups K, M, N, P, and S\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO 13399 standards for tooling data interoperability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for SumiNotch series grooving toolholders and blade bodies that accept the SG-3125 insert seat geometry per ANSI code SG-3125R.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and changed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct insert clamping screw torque per the toolholder manufacturer specification and inspect the insert pocket seat for debris or damage before seating the new insert.
