Measuring 0.0292 inches in diameter with a 135-degree split-point geometry, it starts on location without a center punch and reduces walking on hard surfaces. The straw oxide finish provides lubricity and mild heat resistance. At 1.375 inches overall length with a 0.5-inch flute, this is a compact, heavy-duty bit sized for precision work in tight clearances. It is typically installed by machinists, maintenance technicians, HVAC service techs, and electricians drilling through sheet metal, steel brackets, and control panels.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling steel, stainless, cast iron, aluminum, and non-metallic materials in both production and field-service environments. The regular spiral flute clears chips efficiently at small diameters, reducing the risk of bit breakage in deep relative-to-diameter passes. The straight cylindrical shank accepts standard drill chucks on hand drills, drill presses, and CNC tooling. Its 17xD flute-to-diameter ratio and web-thinned tip are optimized for general-purpose drilling where a small wire-gauge hole is required at consistent tolerance. Series R10CO-R15CO-R18CO denotes the cobalt grade and oxide-finish family within the PRECISION TWIST DRILL lineup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for elevated heat and wear resistance in steel drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split-point tip reduces thrust force and eliminates center-punch requirement\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish adds lubricity and mild corrosion resistance to the cutting surface\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered-web design improves chip evacuation and reduces walking at entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards for heavy-duty jobber drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose wire-gauge drill bit for use in standard 3-jaw drill chucks accepting a 0.0292-inch straight cylindrical shank.

Secure the workpiece firmly before drilling to prevent bit deflection or breakage at this diameter. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend tool life. Operate at manufacturer-recommended spindle speeds for cobalt bits at this diameter, and avoid excessive feed pressure that can snap small-gauge bits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 69\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0292 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt High Speed Steel\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: Straw Oxide (Bronze)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0292 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 17xD\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10CO-R15CO-R18CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5997807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699689095474,"sku":"5997807","price":79.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_ba69570f-8473-44c7-b519-ce23d5898df4.jpg?v=1788379232","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997807-size-69-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
