Mitsubishi JDMW09T320ZDSR-FT VP30RT Carbide Milling Insert (10pc)

The Mitsubishi Materials JDMW09T320ZDSR-FT VP30RT is a new, factory-packaged box of 10 trigon (J-style) double-sided carbide milling inserts from the DIA-EDGE series, made in Japan. The full MPN decodes as follows: J = trigon shape (similar to trigonal/3-corner), D = 20° clearance angle (double-sided/positive), MW = tolerance and chipbreaker class, 09T3 = 9.525 mm (3/8 in) IC size with 3.97 mm thickness, 20 = 2.0 mm nose radius, ZDSR = Mitsubishi's proprietary wiper/geometry chipbreaker (-FT suffix denotes a fine-to-medium cutting FT chipbreaker geometry for stable chip control). The VP30RT grade is a PVD-coated cemented carbide — the "VP" prefix designates Mitsubishi's PVD TiAlN-based coating family, and the "30RT" designation is optimized for high-speed milling of steel (ISO P), stainless steel (ISO M), and cast iron (ISO K) with excellent wear resistance and toughness against interrupted cuts. These inserts are designed for use in Mitsubishi's JDMW-type (Smart Miracle / high-feed) milling cutter bodies and deliver wiper-quality surface finishes; the -FT geometry promotes smooth chip evacuation and reduced cutting forces in medium-depth shoulder and face milling operations.
