DCMT 070202E-FF2 Insert Grade T8430

Experience unmatched precision in fine to medium steel machining with the single-sided positive turning insert from Dormer Pramet. Designed with a fifty-five-degree rhomboid geometry and seven-degree clearance, it meets ISO-tolerance class-M standards for reliable performance. Features and Benefits Rounded edges for smooth machining with light feed and shallow depths, ensuring sufficient edge strength and mitigating work-hardening risks 3-D chip-breaker for precise control across wide feeds and depths of cut Medium-width chip groove reduces cutting resistance and vibration, boosting overall machining performance Shallow chip groove ensures effective chip breaking across a wide range of cutting feeds Raised chip-breaker back wall height forces tighter chip curls, improving chip-breaking for tough materials at lower feeds Neutral geometry enhances impact resistance, allowing for heavier feed and higher depth of cut WC-Co substrate, submicron-grained, provides high hardness, abrasive wear resistance, and comb crack resistance PVD coating enhances thermal cracking resistance, ensuring consistent performance amid cutting temperature fluctuations Multi-layered PVD coating with thick TiN for crater wear resistance, hard AlTiN for flank wear resistance, and unique TiBN layer for reduced build-up edge and improved overall performance Typical Applications Steel Automotive Machinery Toolmaking applications
