Sized to wire gauge No. 50, it measures 0.0700 inches in diameter with a 2-inch overall length. The 135-degree split point reduces walking on entry and cuts through hard alloys with less thrust than a conventional 118-degree point. A straw oxide finish improves surface hardness and heat resistance during high-speed cutting. This bit is built for shop machinists, maintenance technicians, and metalworking tradespeople who need reliable performance on ferrous and non-ferrous substrates.\u003c\/p\u003e\u003cp\u003eThe 5997737 is suited for general-purpose drilling in production and maintenance environments. It handles primary workpiece material codes P, M, K, N, and S, covering carbon steel, stainless steel, cast iron, non-ferrous metals, and heat-resistant alloys. The 1-inch flute length supports drilling to a maximum depth of 1 inch. With a straight cylindrical shank measuring 0.0700 inches in diameter, it seats directly in standard drill chucks and collets without adapters. It is a practical choice wherever a small-diameter, high-strength bit is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree web-thinned split point reduces thrust and minimizes bit walking on entry\u003c\/li\u003e\n\u003cli\u003eStraw oxide coating improves surface hardness and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 14xD flute-to-diameter ratio supports efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collets without modification\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the R10CO-R15CO-R18CO series.

Confirm the workpiece is securely clamped before drilling to prevent rotation and tool breakage. Use appropriate cutting fluid for ferrous materials to prolong tool life and maintain hole quality. Inspect the cutting edges for wear before each use, particularly when drilling hardened or abrasive alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0700 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\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 Diameter\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy Duty Grade\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: ANSI, NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5997737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698119180594,"sku":"5997737","price":51.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_ffa86bd5-03dc-4a46-9b70-d1f47aea6640.jpg?v=1788357983","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997737-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
