Sandvik 6253886 860.1-0850-026A1-NM H10F CoroDrill 860 8.5mm Carbide Drill

The Sandvik Coromant CoroDrill 860 (860.1-0850-026A1-NM H10F) is a new, solid carbide, through-coolant twist drill with a 8.5 mm cutting diameter, 10 mm cylindrical shank (Ø10 per label), and 26.6 mm usable flute length (LU), confirmed directly from the packaging label and part number decode. The grade H10F is Sandvik's uncoated, ultra-fine-grain carbide grade optimized for non-metallic and composite materials — the "-NM" suffix in the part number explicitly designates Non-Metallic (CFRP, GFRP, plastics, graphite) applications, where a non-coated sharp edge prevents delamination and smearing. The "860.1" series denotes a one-flute-length, solid carbide drill with internal coolant channels, A1 connection type (cylindrical shank), designed for use in CNC machining centers with coolant-through capability; the CZCms Ø10 call-out on the secondary label confirms the Ø10 mm shank size and the CZCms toolholder interface compatibility. Made in India per the packaging, this drill ships new in original Sandvik Coromant packaging.
