Built from high speed steel with an oxide coating, it features a 135-degree split point that reduces walking and cutting pressure at contact. The web-thinned, tapered web construction improves chip evacuation and lowers thrust requirements. With a 0.3480-inch cutting diameter, a 4-7\/8-inch overall length, and a 3-1\/2-inch spiral flute, this bit suits a wide range of production and maintenance drilling tasks. It is rated heavy duty and conforms to NAS specification. Right-hand cutting with a regular spiral and two flutes.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in manual drill presses, CNC machining centers, and handheld power drills where letter-size hole tolerances are required. The straight-cylindrical shank fits standard three-jaw chucks without adapters. Typical applications include through-hole drilling in steel, aluminum, and cast iron for fabrication, maintenance, and repair work. No coolant-through capability is present, so external coolant or cutting fluid is recommended when drilling harder materials at sustained feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter S (0.3480 inch) cutting diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and entry pressure\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute, 2-flute design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eHeavy duty grade conforming to NAS specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill bit for any standard drill press, machining center, or power drill equipped with a chuck accepting a 0.3480-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, maintenance technicians, and trade professionals using standard three-jaw drill chucks.
