It carries a wire gauge size of 18, which corresponds to a decimal diameter of 0.1695 inches. The bit is manufactured from high-speed steel with a bright, uncoated finish and features a 135-degree split point for improved centering and reduced walking on hard surfaces. Overall length is 3.25 inches with a flute length of 2.125 inches and a straight cylindrical shank. The parabolic spiral flute design promotes efficient chip evacuation, making this bit well suited to the drilling demands of trade professionals working in metal fabrication, mechanical contracting, and equipment service.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It belongs to the QC21P series and meets ANSI standards for jobber-length drill bits. It is appropriate for hand-held drill motors and drill press applications where a straight-shank, two-flute jobber bit is specified. The maximum drilling depth is 2.125 inches, and no coolant-through capability is provided, so external cooling or lubrication should be applied when drilling harder alloys or deep holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 18 with a decimal diameter of 0.1695 inches for precise bore sizing\u003c\/li\u003e\n\u003cli\u003e135-degree point angle with web thinning reduces thrust and improves self-centering\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\u003eParabolic spiral flute with tapered web configuration promotes chip clearance in deep holes\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without an adapter\u003c\/li\u003e\n\u003cli\u003eMeets ANSI jobber-length standards; QC21P series, heavy-duty grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-duty jobber drill bit for use in any drill press or portable drill motor accepting a straight cylindrical shank up to 0.1695 inches in diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist, maintenance technician, or trade professional familiar with metalworking operations. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Apply appropriate cutting fluid or lubricant when drilling stainless steel, cast iron, or titanium alloys to extend tool life and manage heat buildup. Always wear eye protection and follow applicable shop safety standards when operating drilling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1695 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\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1695 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\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: Parabolic Spiral, 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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: QC21P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 5996972\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51710647828786,"sku":"5996972","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c3de90969c6378087aaa7d157a7434_5aacc69b-f18a-40aa-aa8c-ea6c4eb1a996.jpg?v=1788469073","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996972-jobber-drill-bit-18","provider":"Voomi Supply","version":"1.0","type":"link"}
