Built from cobalt high-speed steel with an oxide and straw coating, this bit delivers added heat resistance and lubricity during cutting. The 135-degree split point geometry reduces walking on entry and lowers thrust force compared to a conventional 118-degree point. The web-thinned, tapered-web design further reduces cutting resistance. Overall length is 1.125 inches, with a 0.3125-inch flute length and a 0.8125-inch straight cylindrical shank. It meets NAS 907 and ANSI standards, making it a recognized choice for controlled, precision drilling in metalworking applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for general-purpose drilling in steel, cast iron, aluminum, non-ferrous metals, and high-temp alloys — covering primary workpiece material codes P, M, K, N, and S. Its compact 1.125-inch overall length makes it appropriate for close-tolerance or confined drilling operations where a standard jobber bit would extend too far. Machinists, tool and die technicians, and maintenance mechanics working on precision components typically reach for wire-gauge cobalt bits in this size range. The regular spiral flute geometry provides good chip evacuation at the drilling depths this diameter supports.\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 compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers entry thrust force\u003c\/li\u003e\n  \u003cli\u003eOxide and straw coating improves lubricity and protects against corrosion during storage\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance and chip packing at depth\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute with 13xD flute-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ANSI standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the PRECISION TWIST DRILL Series R10CO-R15CO-R18CO cobalt jobber drill line. Designed for general-purpose metal drilling applications where a No. 73 wire-gauge hole is required. Compatible with standard drill presses, CNC machining centers, and hand-held drills accepting a straight cylindrical shank of 0.0240 inches diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this drill bit is performed by machinists or maintenance technicians using drill presses, lathes, or CNC equipment. Secure the shank firmly in a collet or chuck before operation and confirm runout is within acceptable limits for the application. Use appropriate cutting fluid or coolant for steel and high-temp alloy materials to extend tool life, noting that this bit does not feature through-coolant capability. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\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: No. 73\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0240 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 and 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: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0240 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.8125 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 13xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Material 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\u003eSeries\u003c\/strong\u003e: R10CO-R15CO-R18CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: 5997822\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51723209081138,"sku":"5997822","price":83.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_d0057c13-2c1a-4db9-a3a9-c497dc459401.jpg?v=1788601961","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997822-no-73-cobalt-jobber-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
