Built from high speed steel with a coated finish, this bit measures 0.1622 inches (4.12 mm) in diameter with an overall length of 2.598 inches (66 mm) and a flute length of 0.866 inches (22 mm). The 120-degree faceted point and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. The straight-cylindrical shank measures 0.236 inches (6 mm) in diameter. This bit is part of the OSG Series 1100 and is intended for use by machinists, tool and die technicians, and metalworking professionals in production drilling environments.\u003c\/p\u003e\u003cp\u003eThe OSG 8595412 is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its screw machine length body provides added rigidity compared to jobber-length bits, making it a practical choice for CNC machining centers, drill presses, and turret lathes where shorter tool overhang improves hole accuracy. The 5xD flute-to-diameter ratio supports efficient chip clearing in moderate-depth holes. This bit covers the decimal inch size range of 0.1500 to 0.2000 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1622 inch (4.12 mm) cutting diameter with tolerance of +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e120-degree faceted drill point for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for lower cutting forces and improved chip flow\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eScrew machine length body for increased rigidity in short-reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute spiral design for standard metalworking operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.
