The Sandvik Coromant 2S221-0300-020-NG H10F is a new, solid carbide straight-shank drill from the CoroDrill 2S221 series, designed for short-hole drilling of non-ferrous and soft materials. The MPN decodes as follows: "2S221" is the CoroDrill series for non-ferrous/composite drilling, "0300" indicates a 3.00 mm cutting diameter, "020" indicates a 20× diameter flute length (60 mm), "NG" denotes no internal coolant (no coolant-through), and the grade H10F is an uncoated fine-grain cemented carbide (WC-Co) optimized for non-ferrous metals, aluminium alloys, plastics, and composites — materials where a TiAlN or similar coating would cause built-up edge. H10F grade provides high hardness and edge sharpness at elevated cutting speeds, making it well suited for precision drilling in aluminium, copper alloys, graphite, and fibre-reinforced plastics. The straight cylindrical shank is compatible with standard precision collet chucks and shrink-fit holders accepting 3 mm shank diameters, and the drill is manufactured to h6 shank tolerance per Sandvik Coromant published standards.
