Technical Ceramics Group), made in Japan, sold in a factory-sealed pack of 10 new inserts. Decoding the ISO designation: D = 55° diamond shape, C = 7° clearance angle, G = ±0.025mm tolerance (precision ground), T = with hole and top clamp features, 11 = 9.525mm (3\/8 in) inscribed circle size, T3 = 3.97mm thickness, 04 = 0.4mm nose radius, MF = medium-finishing chipbreaker geometry; the grade NAM3 is NTK's silicon nitride (Si₃N₄) based ceramic grade QM3, which is designed for high-speed dry finishing and semi-finishing of hardened steels, cast iron, and sintered metals. The QM3\/NAM3 ceramic grade offers exceptional hot hardness and wear resistance, enabling cutting speeds far exceeding those possible with cemented carbide, making it suited for hard turning applications on materials up to approximately 65 HRC. These inserts are compatible with DCGT-style toolholders such as SDJCR\/SDJCL and similar ISO-standard holders accepting a D-shape insert with 7° clearance; the MF chipbreaker geometry is optimized for light-to-medium depth-of-cut finishing passes.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid
