Sandvik N151.2-500-40-4G 235 T-Max Q-Cut Carbide Grooving Insert

The Sandvik Coromant N151.2-500-40-4G 235 is a new, uncoated carbide grooving insert belonging to the T-Max Q-Cut system, specifically designed for parting and grooving operations on CNC lathes. Decoding the ordering code: "N151.2" designates the T-Max Q-Cut insert series with a neutral (N) cutting direction; "500" indicates a 5.00 mm cutting width; "40" denotes the insert height/length class; "4G" specifies the geometry (4-sided, G chipbreaker form for general-purpose grooving); and "235" is the Sandvik carbide grade — an uncoated fine-grain cemented carbide (WC-Co) suited for non-ferrous materials, cast iron, and hardened steels where a sharp, uncoated edge is preferred. Grade 235 is a PVD-TiN coated grade — the gold coloration visible on the insert confirms the TiN coating — recommended for ISO P and M material groups (steel and stainless steel) at cutting speeds of 130 m/min (430 sfm) for P-class steels and 105 m/min (340 sfm) for M-class stainless, with a feed rate of 0.1 mm/rev (0.004 in/rev) as printed on the package label. This insert is compatible with Sandvik T-Max Q-Cut toolholders accepting N151.2-series inserts, including QD-style blade holders, and is sold as a pack of 10 new inserts per the original factory packaging (part number 54930276, MtrIID 5737221, made in India).
