MP2050 Insert Grade Conquers Heat-Resistant Materials


The MP2050 insert grade has an optimized balance of toughness and wear resistance to efficiently machine high-strength, heat-resistant materials. Originally developed specifically for turbine blade machining in the power generation industry segment, the grade also excels in aerospace applications and offers exceptional performance in milling materials such as austenitic and martensitic stainless steels, as well as titanium.


A substrate and a post-treatment applied to its coating enhance MP2050’s capabilities to handle high heat in the cutting zone and to effectively prevent chip adhesion and cutting edge build-up for high process stability and predictability. The combined substrate reliability and wear resistance in the coating overcomes unstable machining conditions such as those involving interrupted cuts, long tool overhangs, and weak fixturing. Additionally, the grade reduces tool costs through longer tool life and allows cutting parameters to be increased, especially in dry machining conditions.


The MP2050 grade range includes round inserts in sizes 10, 12, 16, and 20 mm. Highfeed inserts, square shoulder inserts for Seco’s Turbo, Square 6 and Square T4, and face milling inserts for its Double Octomill are also available.
