Built from high speed steel with an oxide coating, the bit features a parabolic flute geometry and a 130-degree drill point angle with web thinning. Overall length is 5.25 inches, with a flute length of 3.4375 inches. The straight-cylindrical shank and tapered web configuration support accurate chip evacuation and reduced cutting resistance. Licensed tradespeople and machinists working in fabrication, mechanical contracting, and industrial service install this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThe 5059345 is suited for blind hole drilling and stack drilling applications. Its parabolic flute and web-thinned point are engineered for primary workpiece materials including cast iron, non-ferrous metals, and steel. Maximum drilling depth is 2.795 inches. The 8xD flute-to-diameter ratio supports deeper penetration without excessive deflection. This bit is appropriate for both manual drill press operation and CNC setup in light to medium production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter W size, 0.3860 inch decimal diameter with h8 diameter tolerance\u003c\/li\u003e\n  \u003cli\u003e130-degree split-point angle with web thinning for reduced thrust and accurate starting\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation in deep-hole and stack drilling\u003c\/li\u003e\n  \u003cli\u003eOxide finish improves lubricity and light corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI, ISO, BS, and DIN standards; high performance grade designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank drill chucks and collet systems.
