Carrying ISO code QD-NH-0400-0002-CM and grade 4425, this insert features a 0.157 inch cutting width and a neutral lead angle, making it suitable for straight plunge-cut parting applications. The CVD-applied TiCN\/Al2O3\/TiN multilayer coating provides wear resistance across a range of workpiece materials. The CM chipbreaker geometry promotes controlled chip evacuation during cutoff cycles. This insert is installed by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert fits CoroCut QD toolholders configured for the QD-N insert style with H size code. It is suited for parting operations on bar-fed lathes and turning centers where consistent chip control and groove width accuracy are required. The neutral cutting direction and 0-degree lead angle make it appropriate for standard radial cutoff work. With a 7-degree relief angle and a 0.0079 inch corner radius, it is well matched to medium and finishing passes in cutoff applications across steel and other common turned materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.157 inch cutting width for precise parting and grooving\u003c\/li\u003e\n\u003cli\u003eCVD-coated TiCN\/Al2O3\/TiN multilayer finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle and neutral insert hand for straight radial cutoff\u003c\/li\u003e\n\u003cli\u003eCM chipbreaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eGrade 4425 carbide substrate with 7-degree relief angle\u003c\/li\u003e\n\u003cli\u003e0.0079 inch corner radius for accurate groove-bottom geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroCut QD series toolholders accepting QD-N style inserts with H size code.
