Carrying the ISO designation SPMT1212-BR 3210, this insert features a 90-degree square shape with an 11-degree relief angle and a neutral hand orientation. The CVD coating stack -- TiCN, Al2O3, and TiN -- delivers wear resistance and thermal stability suited to demanding cutting conditions. With a 12.65 mm (0.498 inch) inscribed circle and a 1.20 mm (3\/64 inch) corner radius, this insert is built for controlled boring passes where dimensional accuracy matters. It is held in place by a screw-clamp method and uses the T chipbreaker geometry.\u003c\/p\u003e\u003cp\u003eThis insert belongs to the CoroBore 111 series and is intended for use in compatible CoroBore 111 boring bar assemblies. It suits precision internal turning and fine boring operations in ferrous metals and other materials where CVD-coated carbide grade 3210 is appropriate. Typical applications include production machining environments in shops running CNC lathes and boring mills. Each package contains one insert, making it straightforward to order exact quantities for tooling management.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD coating process with TiCN, Al2O3, and TiN layers for extended tool life\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate with manufacturer grade 3210 for thermal and wear resistance\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 90-degree included angle for versatile cutting geometry\u003c\/li\u003e\n\u003cli\u003e1.20 mm (3\/64 inch) corner radius for controlled surface finish in boring operations\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard screw-clamp toolholders\u003c\/li\u003e\n\u003cli\u003eT chipbreaker geometry for chip control during internal turning passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroBore 111 series boring bars and compatible SPMT-seat toolholders that accept a screw-clamp holding method.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert replacement and seating should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Ensure the insert pocket and clamping screw are clean and free of chips before seating the new insert.
