It features a two-flute, regular spiral design with a tapered web configuration and a web-thinned tip for reduced thrust during entry. The bright, uncoated finish is suitable for general-purpose drilling in a wide range of metals. Overall length is 4-5\/8 inches with a flute length of 3-5\/16 inches. The straight-cylindrical shank matches the drill bit diameter at 21\/64 inches, making it compatible with standard drill chucks. This bit is part of the R10P series and meets ANSI standards.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for production and maintenance drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is suited for use in drill presses, lathes, and hand-held power drills across machine shops, fabrication facilities, and general metalworking environments. The 10xD flute-to-diameter ratio provides adequate chip clearance for moderate-depth drilling operations. With a maximum drilling depth of 3-5\/16 inches, it handles the majority of standard through-hole and blind-hole applications encountered in trade and industrial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21\/64 inch (0.3281 inches) diameter with matching straight-cylindrical shank for secure chuck engagement\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction suitable for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design with tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to obscure wear and allow easy inspection\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; Series R10P general-purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose OEM-style jobber drill bit compatible with standard three-jaw drill chucks accepting a 21\/64 inch straight-cylindrical shank.
