It features a 1.0156-inch (1-1\/64 inch) diameter, a 3MT (Morse Taper 3) shank, and is manufactured from high speed steel with an oxide finish for improved lubricity and corrosion resistance. The 118-degree standard point angle suits general-purpose drilling in a wide range of ferrous and non-ferrous materials. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations. This bit is used by machinists, toolroom technicians, and maintenance mechanics working with drill presses, lathes, and milling machines equipped with a Morse taper spindle.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for general-purpose production and maintenance drilling where a Morse Taper 3 shank interface is required. The 6.5-inch flute length relative to the 1.0156-inch diameter yields a 4xD flute-to-diameter ratio, making it suitable for moderate-depth holes without excessive deflection. It conforms to ANSI standards for taper shank drill bits and carries a Series 209 designation. Typical applications include drilling structural steel, cast iron, aluminum, and similar materials in job shop, plant maintenance, and fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.0156-inch (1-1\/64 inch) diameter with a 3MT Morse Taper shank for secure spindle engagement\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide finish for general-purpose durability\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip to reduce thrust and improve centering\u003c\/li\u003e\n  \u003cli\u003e6.5-inch spiral flute length (4xD ratio) for efficient chip evacuation in moderate-depth holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; compatible with standard drill press and lathe spindle rotation\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for taper shank drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or production taper shank drill bit for machine tools fitted with a Morse Taper 3 spindle or sleeve, including drill presses, lathes, and milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool operators. Ensure the machine spindle is fully powered down and at rest before inserting or removing the taper shank. Clean both the bit taper and spindle socket of chips and oil before seating to prevent slippage under load. Secure the bit with a proper drift and knockout bar when removing; never use a hammer directly on the fluted body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.0156 inches (1-1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 11.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 3MT (Morse Taper 3)\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 209\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: 0.5 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: 5999470\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694220673330,"sku":"5999470","price":162.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91f3c7609b9c9ca5a8425dc07c240c2d_070445e9-9b33-495a-9e51-afdad985e4ec.jpg?v=1788321810","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999470-taper-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
