Built from high-speed steel with a bright, uncoated finish, it features a 118-degree standard point angle and a spiral, web-thinned flute configuration for efficient chip evacuation. The 1\/16-inch diameter bit has an overall length of 3 inches and a flute length of 1-3\/4 inches, giving it extended reach compared to jobber-length equivalents. Right-hand cut with a cylindrical shank, it is suited for use in drill presses, CNC drilling setups, and hand-held power drills in trade and light industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for drilling aluminum, aluminum alloy, copper, magnesium, and magnesium alloy. The taper length format provides added reach for applications where standard jobber-length bits fall short, such as deep-hole work in fabrication, mechanical, plumbing rough-in, and electrical panel work. The R51FS series is built to ANSI standards, making it appropriate for consistent performance in general-purpose production and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction rated for aluminum, copper, magnesium, and related alloys\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for accurate entry on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute type promotes rapid chip evacuation in soft metals\u003c\/li\u003e\n  \u003cli\u003eTaper length OAL of 3 inches with 1-3\/4-inch flute length for extended reach drilling\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant general-purpose grade suitable for production and maintenance use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in materials including aluminum, aluminum alloy, copper, magnesium, and magnesium alloy.

Secure the workpiece firmly before drilling to prevent walking on entry, particularly in soft metals. Use appropriate cutting fluid or lubrication when drilling copper and aluminum alloys to extend tool life and improve finish quality. Inspect the bit for wear or chipping before each use and replace if the cutting edges are dull or damaged.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R51FS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches\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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Fast)\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: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: 5998977\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51719087456562,"sku":"5998977","price":99.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7fe516686099e0e67fc128f8cb35071d.jpg?v=1788557355","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998977-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
