Ground to a 118-degree faceted point with web thinning for reduced thrust at entry, this bit cuts right-hand with a regular spiral flute pattern. The 7\/16 inch (0.4375 inch) diameter is held to a tight tolerance of -0.0005 to 0.0000 inches, making it suitable for close-tolerance hole work. At 4.5 inches overall length with a 2.875-inch flute and a straight-cylindrical shank, it fits standard drill chucks and CNC tool holders. Manufactured from micrograin solid carbide in Series 101, it meets DIN 338 standards. Machinists, tool-and-die workers, and CNC operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for metalworking, mold-making, and precision machining environments where carbide is required over high-speed steel. The 5xD flute-to-diameter ratio and tapered web configuration make it effective in ferrous and non-ferrous metals, hardened steels, and other abrasive materials. The bright uncoated finish allows for close visual inspection of the cutting edges before and after use. It is sold individually and fits into standard jobber-length drill applications on manual mills, lathes, and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of -0.0005 to 0.0000 inches for close-tolerance hole requirements\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with 5xD ratio supports chip evacuation over the 2.875-inch flute length\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 7\/16 inch shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 standard; no coolant-through feature, suited for external coolant or dry cutting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit compatible with standard straight-shank drill chucks, collet systems, and CNC tool holders accepting a 7\/16 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or CNC operators. Secure the shank fully into a properly sized chuck or collet and verify runout before cutting. Power down or lock out the spindle before inserting or removing the bit.
