It features a 0.1929-inch (4.90 mm) diameter, a 120-degree faceted point angle, and a two-flute spiral geometry with web thinning for improved chip evacuation and reduced thrust. Built from high speed steel with a coated finish, this bit delivers consistent performance across a range of ferrous and non-ferrous workpiece materials. The straight-cylindrical shank and compact screw machine length make it well suited for drill presses, CNC machines, and turret lathes where rigidity and repeatability matter.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in metalworking applications including production drilling, fabrication, and machining operations. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length profile reduces overhang and improves rigidity compared to jobber-length bits, making it a common choice for close-tolerance hole drilling in a shop or production floor setting. It is typically installed and used by machinists, tool-and-die professionals, and maintenance technicians working with standard drill presses or CNC equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1929-inch (4.90 mm) diameter with a tight tolerance of +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e120-degree faceted point angle for accurate self-centering on metal surfaces\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral geometry with web thinning for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eTapered web configuration reduces cutting force and heat buildup\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank sized at 6.00 mm for secure chuck retention\u003c\/li\u003e\n\u003cli\u003eScrew machine length with 5xD flute-to-diameter ratio for added rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.
