Horn L105.0045.0.1 TN35 Supermini Carbide Grooving Insert (2pc)

The Horn L105.0045.0.1 TN35 is a new, solid carbide Supermini grooving/parting insert from Paul Horn GmbH, made in Germany, belonging to the System 105 Supermini series designed for small-bore internal grooving, parting, and profiling on CNC lathes and Swiss-type turning machines. The part number decodes as follows: "L105" = System 105 Supermini left-hand insert body; "0045" = 0.45 mm cutting width; "0.1" = 0.10 mm corner radius; "TN35" = Horn's TN35 PVD TiAlN-based coating grade, optimized for steels, stainless steels, and hardened materials at elevated cutting temperatures. The TN35 grade features a PVD TiAlN multilayer coating that provides high wear resistance and thermal stability, enabling dry or minimum-quantity lubrication cutting. This insert is compatible with Horn System 105 Supermini toolholders and boring bars and is suited for internal grooving, undercuts, and profiling in bores as small as approximately 5 mm diameter; the 0.45 mm cutting width and 0.10 mm nose radius make it particularly appropriate for fine, precision groove geometries in steel, stainless, and alloyed materials.
