Built to the CoroCut QD series specification, this insert carries the ISO code QD-NH-0400-0003-CR 4425 and features a 0.157-inch cutting width with a neutral lead angle and neutral hand orientation. The grade 4425 substrate is coated with a CVD-applied TiCN\/Al2O3\/TiN multilayer finish that resists heat and abrasion during interrupted and continuous cuts. A 7-degree relief angle and 0.0118-inch corner radius (chipbreaker code CR) define the cutting geometry. This insert is installed by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 7861026 is suited for parting off bar stock and grooving operations on steel, stainless steel, and other materials where a neutral cutting direction is required. The CoroCut QD system is engineered for stable, precise cutoff work on medium to large diameter workpieces in both light and heavy production settings. The CVD TiCN\/Al2O3\/TiN coating extends tool life across a range of cutting conditions. This insert is sold individually per package with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.157-inch cutting width optimized for parting and grooving operations\u003c\/li\u003e\n\u003cli\u003eGrade 4425 carbide substrate with CVD-applied TiCN\/Al2O3\/TiN multilayer coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle and neutral hand orientation for straight-plunge cutoff applications\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle with 0.0118-inch corner radius and CR chipbreaker geometry\u003c\/li\u003e\n\u003cli\u003ePart of the CoroCut QD series, engineered for stable deep grooving and parting\u003c\/li\u003e\n\u003cli\u003eISO code QD-NH-0400-0003-CR 4425 for cross-reference and toolholder matching\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroCut QD series QD-N style toolholders that accept the H insert size code.
