Sandvik 870-1450-14-PM 4334 CoroDrill 870 Carbide Drill Insert (2pc)

This is a new Sandvik Coromant 870-1450-14-PM 4334 CoroDrill 870 indexable carbide drill insert, a peripheral (outer) insert designed for use in Sandvik CoroDrill 870 indexable insert drills. The ordering code breaks down as follows: 870 = CoroDrill 870 system; 1450 = 14.50 mm compatible drill diameter range; 14 = insert size/seat designation; PM = chipbreaker geometry optimized for P- and M-material groups (steel and stainless steel); grade 4334 is a PVD-coated cemented carbide grade with a fine-grained substrate and a TiAlN-based PVD coating, designed for excellent wear resistance and edge toughness in steel and stainless steel drilling. Recommended cutting data for P-materials (steel, ≤175 HB) are fn 0.011 in/r (range 0.006–0.018) and vc 360 sfm (range 260–460); for N-materials (non-ferrous/aluminum, ≤90 HB) fn 0.012 in/r (range 0.008–0.016) and vc 690 sfm (range 520–820), as shown on the label. The insert seats into the CoroDrill 870 body and is retained via a Torx-style clamping screw (the black oxide-finished screw and driver pin visible in the first photo are included); two inserts are visible in the plastic cassette, confirming this is a 2-piece pack.
