The 135-degree split point with web thinning reduces the thrust required to start the hole and helps prevent walking on hard surfaces. At 3.75 inches overall length with a 2.5-inch flute length, this bit fits standard three-jaw chucks and meets ANSI and NAS 907 dimensional standards. The oxide and straw finish provides a degree of lubricity and surface protection during high-heat cutting operations. It is used primarily by machinists, tool-and-die workers, and maintenance technicians drilling in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 5997773 is suited for drilling steel, cast iron, aluminum, and other materials covered under workpiece material codes P, M, K, N, and S. The 12xD flute-to-diameter ratio and regular spiral flute geometry support efficient chip evacuation in through-hole and blind-hole applications. The straight cylindrical shank at 0.2040 inch diameter seats securely in hand drills, drill presses, and CNC machining centers. This bit is sold individually and is part of the R10CO-R15CO-R18CO series, which covers cobalt jobber-length drills in this size range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eNo. 6 wire size, 0.2040 inch decimal diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and eliminates center-punch requirement on many surfaces\u003c\/li\u003e\n\u003cli\u003eOxide and straw finish adds surface lubricity and corrosion resistance during cutting\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry with tapered web promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 standards for dimensional accuracy and material specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the PRECISION TWIST DRILL R10CO-R15CO-R18CO cobalt jobber series.

Secure the shank fully in the chuck and verify runout before beginning a cut. Do not exceed the recommended maximum drilling depth of 2.5 inches without retracting the bit to clear chips. Always wear appropriate eye protection and ensure the workpiece is properly fixtured before drilling.\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. 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2040 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, Web-Thinned\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\u003eFlute Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.5 inches\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (codes P, M, K, N, S)\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5997773\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695344124210,"sku":"5997773","price":16.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_c1f1f095-e155-4ae9-a3c1-b4d94a4e4c48.jpg?v=1788334074","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997773-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
