Sandvik 870-2010-20-PM 4334 CoroDrill 870 Carbide Drill Insert

The Sandvik Coromant 870-2010-20-PM in grade 4334 is a new indexable carbide drill insert for the CoroDrill 870 modular drill system, designed for use as a peripheral (outer) insert in 870-series drill bodies. Grade 4334 is a PVD-coated cemented carbide grade optimized for drilling steel (ISO P) and non-ferrous/aluminum (ISO N) materials — confirmed by the package label listing P and N workpiece material groups with corresponding cutting data. The PM designation indicates a Peripheral/Middle seat geometry with the -PM chipbreaker, and the insert measures 20 mm in inscribed circle diameter (IC) as decoded from the ordering code (2010 = 20.0 mm IC, 10 = thickness index). Per the cutting data label, recommended feed for steel (P2.1.Z.AN, 175 HB) is 0.33 mm/rev (0.013 in/rev) at 110 m/min (360 SFM), and for aluminum (N1.3.C.AG, 90 HB) is 0.35 mm/rev (0.014 in/rev) at 210 m/min (690 SFM); this insert is compatible with Sandvik CoroDrill 870 drill bodies of the corresponding diameter range and is not interchangeable with other indexable drill platforms.
