It carries a wire gauge size of 51, equal to 0.0670 inches (1.70 mm) in diameter, with an overall length of 1.6535 inches (42.00 mm). The bit is manufactured from vanadium high speed steel and features a titanium nitride (TiN) coating that extends surface hardness and wear resistance. A 140-degree faceted point angle reduces thrust and improves accuracy on entry, while a web-thinned, tapered web design lowers cutting resistance. This bit is sold individually and suited for use in machine shops, CNC drilling operations, and production environments where compact bit length improves rigidity and reduces deflection.\u003c\/p\u003e\n\u003cp\u003eThe OSG 61517 is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. Its screw machine length profile makes it a practical choice for drill press, turret lathe, and CNC machining center applications where a shorter bit reduces runout and chatter. The 5xD flute-to-diameter ratio and regular spiral flute geometry support consistent chip evacuation in through-hole and blind-hole drilling at small diameters. Machinists and tool-and-die professionals working in production or repair settings will find this bit appropriate for precision small-diameter work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 51 (0.0670 inches \/ 1.70 mm) diameter with a tight tolerance of +0 to -0.014 mm\u003c\/li\u003e\n  \u003cli\u003eTiN coating over vanadium high speed steel for extended tool life on ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted point angle reduces entry thrust and improves positional accuracy\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting force at small diameters\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 1.6535 inches OAL improves rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute and straight cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-use drill bit for any standard straight-shank drill chuck accepting a 3.00 mm (0.118 inch) shank diameter in drill press, lathe turret, or CNC machining center setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by a machinist or tool operator into a compatible straight-shank chuck; verify chuck capacity accepts the 3.00 mm shank before seating. Secure the shank fully and confirm runout before starting a cut. Always power down and de-energize the machine spindle before changing tooling. Use appropriate cutting fluid or lubrication when drilling stainless steel or harder alloys to preserve coating life.\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: 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 1.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.6535 inches (42.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eFlute Length\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.014 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734544286002,"sku":"61517","price":32.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3abe3794031a9748ccfe4c5ce7e40a2.jpg?v=1788763435","url":"https:\/\/voomisupply.com\/products\/osg-61517-screw-machine-drill-bit-wire-51-0-0670-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
