Manufactured from high speed steel with a bright, uncoated finish, this bit features a 118-degree standard point angle and a right-hand spiral flute for efficient chip evacuation. The web-thinned, tapered web configuration reduces thrust requirements at the point, making it well-suited for production and maintenance drilling applications. At 0.1875 inches in diameter with a 5.75-inch overall length, this bit belongs to the R51FS series and conforms to ANSI standards.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in aluminum, aluminum alloy, copper, magnesium, and magnesium alloy. The taper length design provides additional flute length compared to jobber-length bits, making it appropriate for applications requiring deeper hole depths or improved chip clearance. The cylindrical shank fits standard drill chucks without adapters, and the fast spiral flute type supports efficient cutting in soft, gummy materials common in light manufacturing and mechanical service environments. Machinists, maintenance technicians, and tool-and-die professionals are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute promotes chip evacuation in aluminum, copper, and magnesium alloys\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suits non-ferrous and soft metal applications\u003c\/li\u003e\n  \u003cli\u003e3.375-inch flute length with a 6xD flute-length-to-diameter ratio for extended reach\u003c\/li\u003e\n  \u003cli\u003eCylindrical shank with no threading for direct chuck mounting\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards; R51FS series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling aluminum, aluminum alloy, copper, magnesium, and magnesium alloy workpieces.

Secure the workpiece firmly before drilling and ensure the chuck is tightened fully on the cylindrical shank before operation. Do not exceed the recommended surface footage for high speed steel tooling in the material being drilled. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows signs of damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool 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\u003eFlute Type\u003c\/strong\u003e: Spiral (Fast)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Aluminum Alloy, Copper, Magnesium, Magnesium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R51FS\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: 5998743\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695403860274,"sku":"5998743","price":24.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74c9fe7d315ca811984a3fdec916a1a1.jpg?v=1788334642","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998743-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
