Built from cobalt high-speed steel with a straw oxide finish, it runs a 135-degree split point that reduces walking on entry and cuts through harder stock without requiring a center punch. The straight cylindrical shank measures 0.076 inches in diameter, matching the No. 48 wire size, and the overall length is 2 inches. With a web-thinned, tapered-web design and regular spiral fluting, this bit is built for consistent chip evacuation and extended tool life in production and maintenance drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling steel, cast iron, non-ferrous metals, and composites in residential, commercial, and industrial settings. The cobalt construction makes it a practical choice for harder alloys and stainless steel where standard high-speed steel bits wear prematurely. Typical install scenarios include HVAC techs drilling sheet metal for fasteners or brackets, plumbers drilling through hangers and strapping, and electricians drilling metal panels and enclosures. It is sold individually but must be ordered in multiples of 12 per the manufacturer minimum order requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 48 wire size with 0.076-inch decimal diameter for precise, tight-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction provides superior heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust, minimizes bit walking, and improves hole entry accuracy\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish adds lubricity and corrosion resistance for extended service life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered-web design promotes efficient chip clearing and reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards for dimensional accuracy and material performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the R10CO-R15CO-R18CO series. Designed for use in standard drill chucks and drill presses accepting straight cylindrical shanks with a 0.076-inch shank diameter. Compatible primary workpiece material codes include P, M, K, N, and S per ISO classification, covering steel, stainless, cast iron, non-ferrous, and high-temperature alloys.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit is appropriate for licensed tradespeople and experienced machinists. Ensure the drill chuck is clean and the bit is seated fully and centered before tightening. Use cutting fluid when drilling harder steels or stainless to reduce heat buildup and extend bit life. Do not exceed recommended drilling depth of 1 inch for this bit size.\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: No. 48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0760 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\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0760 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\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-to-Diameter Ratio\u003c\/strong\u003e: 13xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose \/ Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel and Multi-Material (ISO codes P, M, K, N, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 5997883\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51700435452210,"sku":"5997883","price":51.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_ff3a9a2d-aa11-417e-b4d9-ced57ad6c814.jpg?v=1788390308","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997883-no-48-cobalt-jobber-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
