The tip is manufactured from solid carbide with a TiAlN coating applied via PVD process, delivering strong wear resistance and thermal stability at the cutting edge. The drill features a 20mm cutting diameter (0.7874 inches) and a 142-degree included angle, which suits a wide range of workpiece materials and drilling conditions. This tool is intended for use by machinists and metalworking professionals in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThe 7357986 fits the CoroDrill 870 replaceable tip system, which uses a dedicated insert seat size 20 body. This modular design allows the carbide tip to be swapped without replacing the entire drill body, reducing tooling cost per hole over time. The PM insert geometry and 4334 grade combination is suited for drilling steel and cast iron at controlled feed and speed parameters. It does not include through-spindle coolant capability, so coolant delivery must be managed externally or via flood application.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide tip with TiAlN PVD coating for wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003e20mm cutting diameter (0.7874 inches) with 142-degree included angle\u003c\/li\u003e\n\u003cli\u003ePM insert geometry with manufacturer grade 4334\u003c\/li\u003e\n\u003cli\u003eModular CoroDrill 870 system with insert seat size 20 compatibility\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design — suited for flood or external coolant setups\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.055 pounds for easy handling and tool change\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CoroDrill 870 series drill bodies with insert seat size 20.
