It features a 118-degree drill point angle, a fast spiral flute geometry with a 35-degree helix angle, and a tapered web configuration. The flute length measures 0.75 inches (19.05 mm), and the overall length is 1.5 inches (38.10 mm). Manufactured to a diameter tolerance of -0.0005 to +0.0000 inches, this bit delivers consistent, precise holes in demanding applications. It is supplied uncoated and carries a heavy-duty grade designation. Machinists, PCB fabricators, and precision drilling technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in fast, precise drilling of circuit boards and related precision components. It is well suited to production and repair environments where tight diameter tolerances are required. The fast spiral flute design promotes efficient chip evacuation in cast iron, non-ferrous metals, plastics, and steel. The right-hand cutting direction makes it compatible with standard CNC drilling machines and hand drill presses used in electronics manufacturing and metalworking shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard or abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle suits a broad range of workpiece materials including cast iron and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute with 35-degree helix angle promotes rapid chip clearance and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves centering accuracy and reduces walking on entry\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of -0.0005 to +0.0000 inches supports precision hole sizing for PCB and tight-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows direct inspection of tool condition and is compatible with standard regrinding procedures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision drill bit for use in standard CNC and bench-top drilling equipment that accepts a 0.1590-inch (4.04 mm) shank diameter.
