Built from heavy-duty cobalt steel, this bit runs a 135-degree split point that self-centers on contact and reduces walking on hard surfaces. The bright\/uncoated finish is standard for cobalt-grade tooling. At 5\/16 inch (0.3125 inches) in diameter with an overall length of 2-13\/16 inches, it fits standard drill chucks and machine spindles. Licensed machinists, tool and die professionals, and HVAC or plumbing fabricators reach for cobalt bits when high-speed steel is not enough for stainless, hardened steel, or cast alloys.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production and maintenance drilling where a shorter, stiffer screw machine length profile reduces deflection and improves hole accuracy. The shorter flute length relative to jobber-length bits makes it a preferred choice in confined spaces, drill presses, CNC turrets, and manual lathes. The straight-cylindrical shank seats securely in standard Jacobs-style chucks and collet systems. Typical applications include metalworking shops, mechanical contractors drilling structural steel, and field service techs drilling through equipment frames or brackets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHeavy-duty cobalt construction for drilling hardened, stainless, and high-alloy steels\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers and reduces thrust force on entry\u003c\/li\u003e\n\u003cli\u003eScrew machine length profile increases rigidity and reduces bit deflection\u003c\/li\u003e\n\u003cli\u003e2-flute spiral configuration for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit for applications requiring a 5\/16 inch diameter cobalt bit with a straight-cylindrical shank, conforming to NAS 907 Type J specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, mechanical contractors, or field service technicians using standard drill presses, CNC machines, or handheld power drills. Always ensure the shank is fully seated and secured in the chuck before operation. Use appropriate cutting fluid or coolant for extended tool life when drilling hardened or stainless materials. Follow shop safety standards and applicable OSHA guidelines for rotating tool operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.625 inches (1-5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD32520\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51753668051250,"sku":"CD32520","price":17.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54372cdd8d04e566e12f562cd92e481c_5627ce51-725e-4277-949a-0df6902d23cf.jpg?v=1788939267","url":"https:\/\/voomisupply.com\/products\/titan-usa-cd32520-5-16-inch-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
