Decoding the part number: the S312 system designates Horn's three-edged (triangular) precision grooving insert series with a central clamping hole; 0300 encodes a 3.00 mm cutting width; 52 denotes the insert geometry\/chipbreaker variant; and TF45 is Horn's PVD-coated submicron carbide grade, a TiAlN-based coating specifically engineered for universal grooving and parting applications including steel, stainless steel, and cast iron. The TF45 grade provides excellent hot hardness and wear resistance at moderate-to-high cutting speeds, making it well-suited for external grooving, parting-off, and face grooving on CNC lathes using compatible Horn S312-series toolholders. Each insert features three usable cutting edges and a precision-ground top face with an integrated chipbreaker to promote short chip formation and reliable chip evacuation in interrupted or continuous grooving cuts.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct
