Decoded from the part number: \"S312\" identifies the System 312 insert family; \"0300\" indicates a 3.00 mm groove width; \"52\" encodes the geometry\/chipbreaker variant; and \"TF45\" is Horn's PVD-coated submicron carbide grade offering high hot hardness and wear resistance suited to moderate-to-high cutting speeds on steel, stainless, and difficult-to-machine alloys. The triangular insert body features three usable cutting edges, a central through-hole for screw clamping, and precision-ground flanks for accurate, repeatable seating in compatible Horn System 312 toolholders. TF45's PVD TiAlN-based coating delivers low friction and oxidation resistance, extending tool life in dry or minimum-quantity lubrication (MQL) machining environments.\u003c\/p\u003e\n\u003ch3
