This is a new box of 10 Sumitomo Electric TPMT090204N-LU (ANSI TPMT1.81.51ELU) triangular carbide turning inserts in grade AC820P, made in Japan. The TPMT geometry is a 60° triangle with 11° positive clearance, M-class tolerance, a center hole and a single-sided chipbreaker, giving 3 usable cutting edges per insert with a 0.4 mm (1/64 in) nose radius. The LU chipbreaker is rated for finishing (F) and light-to-continuous cutting, and AC820P is a coated carbide grade for steel (ISO P) and stainless steel (ISO M). The box label gives a cutting speed of 270 m/min (200-340 m/min), or 890 SFM (660-1115 SFM), and a feed of 0.1 mm/rev (0.05-0.25 mm/rev), or 0.004 IPR (0.002-0.01 IPR). Inserts are for turning and boring holders with a triangular TP-style pocket in the 09-size range.
