Built to wire gauge size 74, it measures 0.0225 inches in diameter with a 1 inch overall length. The 135-degree split point promotes accurate self-centering and reduces walking on entry, making it well suited for production drilling where consistency matters. An oxide and straw finish provides a degree of lubricity and corrosion resistance. The bit features a standard straight cylindrical shank and two regular spiral flutes with a web-thinned, tapered web configuration for efficient chip evacuation. It meets ANSI and NAS 907 standards and is rated for heavy-duty general-purpose drilling by the manufacturer.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in hand-held or machine-mounted drilling applications where small-diameter precision holes are required. The cobalt construction makes it appropriate for cutting steel, stainless, cast iron, and similar hard materials that would rapidly dull a standard high-speed steel bit. Series R10CO-R15CO-R18CO. Typical users include machinists, tool and die technicians, aerospace maintenance technicians, and industrial MRO professionals working with close-tolerance hole requirements. The 1\/4 inch maximum drilling depth and compact 1 inch overall length suit it for shallow-hole applications in tight clearance conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for improved heat resistance and tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web for efficient chip removal in small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003eOxide and straw coating for light lubricity and surface protection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with regular spiral flutes\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards; rated heavy-duty general purpose\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber drill bit in Series R10CO-R15CO-R18CO, suitable for use in standard straight-shank drill chucks and compatible with any spindle or hand tool accepting a 0.0225 inch straight shank.

Before mounting, ensure the drill chuck or collet is clean and free of debris to prevent runout at this small diameter. Secure the shank fully within the chuck jaws and verify concentricity before beginning a cut. At wire-gauge diameters, even minor misalignment or excessive feed pressure can cause bit breakage; follow the drill press or machine tool manufacturer's recommended feed and speed tables for cobalt bits in the target material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 74\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0225 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0225 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 11xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10CO-R15CO-R18CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5997825\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709970907442,"sku":"5997825","price":83.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_9323013a-b44b-45e8-a14c-cc7b33febe5b.jpg?v=1788462697","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997825-cobalt-jobber-drill-bit-74","provider":"Voomi Supply","version":"1.0","type":"link"}
