It features a 51\/64 inch (0.7969 inch decimal) cutting diameter with a reduced 1\/2 inch straight-cylindrical shank, allowing it to be chucked in standard 1\/2 inch drill chucks without requiring a larger chuck capacity. The bit is manufactured from high speed steel with a bright uncoated finish and ground to a standard 118-degree point angle for reliable starts on flat and curved surfaces. Overall length is 6 inches with a 3 inch flute length, supporting a maximum drilling depth of 3 inches.\u003c\/p\u003e\n\u003cp\u003eThis bit is well suited for metal fabrication shops, maintenance and repair operations, and general industrial drilling tasks. The Series R56 designation places it in PRECISION TWIST DRILL's standard general-purpose line. The reduced shank design is particularly useful when drilling large-diameter holes with equipment limited to 1\/2 inch chuck capacity, a common situation on portable drill presses, handheld power drills, and light machine tools. Right-hand spiral flutes clear chips efficiently in ferrous and non-ferrous workpieces alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e51\/64 inch cutting diameter with reduced 1\/2 inch shank for use in standard 1\/2 inch chucks\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry and self-centering starts\u003c\/li\u003e\n  \u003cli\u003e3 inch flute length with regular spiral for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup that can affect tolerance on close-fit holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, ANSI standard geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any drill press, milling machine, or power drill with a 1\/2 inch or larger chuck.

Always wear appropriate eye protection and secure the workpiece before drilling. Use cutting fluid or coolant on harder ferrous materials to extend bit life, even though this bit is rated for dry use. High speed steel bits should not be used at feeds and speeds intended for carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 51\/64 inch (0.7969 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Aluminum, Cermet, Copper, Magnesium, Nickel, Synthetic, Titanium\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: R56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 5999670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709796942130,"sku":"5999670","price":90.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3f378707cbc28694249b8f6f1c46405.jpg?v=1788460590","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999670-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
