It features a 135-degree split point with web thinning for fast engagement and reduced walking on hard materials. The straw oxide finish provides a measure of heat resistance during continuous drilling operations. With a 2-flute regular spiral flute design and straight shank, this bit is suited for production drilling in steel, stainless, cast iron, non-ferrous metals, and high-temp alloys. It meets NAS 907 and ANSI standards, making it appropriate for aerospace and precision machining environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for drilling steel and a broad range of workpiece materials including ferrous metals, cast materials, non-ferrous alloys, and special alloys. The 14xD flute-to-diameter ratio delivers efficient chip evacuation in jobber-depth holes. Typical use cases include maintenance and repair operations, production line drilling, and toolroom work where a general-purpose cobalt bit is required. It is sold individually but must be ordered in multiples of 12.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge 43 diameter, 0.0890 inches, for precision small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust and prevents walking\u003c\/li\u003e\n  \u003cli\u003eCobalt construction for improved heat and wear resistance versus standard HSS\u003c\/li\u003e\n  \u003cli\u003eStraw oxide coating adds surface hardness and mild lubricity\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, 2-flute design promotes consistent chip removal\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ANSI specifications for aerospace-grade dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the Series R10CO-R15CO-R18CO cobalt jobber drill line.

Secure the shank fully in the chuck before operation to prevent runout. When drilling steel or hard alloys, use a cutting fluid to extend tool life and control heat buildup. Inspect the cutting edges before each use and replace any bit showing chipping or heat discoloration at the tip.\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: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0890 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\u003ePoint Type\u003c\/strong\u003e: Standard Split Point, Web-Thinned\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: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.00 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 14xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel and multi-material (P, M, K, N, S classifications)\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: NAS 907, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy Duty Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10CO-R15CO-R18CO\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: 5997802\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722040279346,"sku":"5997802","price":54.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_d7a34955-e2ab-4994-bcbb-e979557c397a.jpg?v=1788584556","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997802-jobber-drill-bit-43-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
