It measures 0.1960 inches in diameter and 3.625 inches overall, with a 2.4375-inch spiral flute length. The 135-degree split point reduces walking on entry and lowers thrust force compared to a standard 118-degree point. Web thinning further eases penetration in harder stock. This bit is sized for general-purpose drilling in metal fabrication, mechanical, and maintenance environments and is typically installed by machinists, maintenance technicians, and pipefitters using a standard drill press or hand drill.\u003c\/p\u003e\u003cp\u003eThis bit is rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. The straight-cylindrical shank fits standard three-jaw drill chucks without adapters. With a flute-to-diameter ratio of 12xD and a maximum drilling depth of 2.4375 inches, it handles through-hole and blind-hole operations in common structural and mechanical stock. It is built to the ANSI standard and conforms to NAS 907 specification, making it suitable for aerospace and heavy-duty industrial applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 9 wire size, 0.1960 inch diameter with straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces drill walk and cutting thrust\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating provides mild lubricity and corrosion resistance during cutting\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral with tapered web configuration for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standard and NAS 907 specification for heavy-duty and aerospace-grade applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber length drill bit compatible with any standard three-jaw chuck accepting a 0.1960-inch straight-cylindrical shank, across drill presses, lathes, and hand-held power drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or trade technicians familiar with metalworking drill procedures. Secure the workpiece and verify chuck grip on the full shank before operation. Use appropriate cutting fluid or lubricant when drilling stainless steel, superalloys, or titanium to extend tool life and prevent work hardening. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is degraded.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1960 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1960 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\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\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10B-R15B-R18B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: 5997670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698483724594,"sku":"5997670","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7da465a3340ea6a9db91bc6a63822e95_8945cdd8-fc29-47bb-b9eb-8b894e020474.jpg?v=1788363590","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997670-no-9-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
