At 12 inches overall length with a 9-inch spiral flute, this bit reaches into cavities and deep workpieces that standard-length bits cannot access. The 0.1562-inch diameter and 118-degree standard point angle make it a general-purpose tool suited for a wide range of metalworking tasks. The uncoated HSS construction and web-thinned, tapered web configuration reduce thrust requirements and promote cleaner entry into workpiece material. Cutting direction is right hand with a regular spiral and two flutes.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in machine shop, toolroom, and field maintenance applications where extended reach is required. Primary workpiece materials include aluminum, magnesium, copper, nickel, synthetic materials, and titanium. Secondary workpiece material compatibility covers stainless steel, steel, malleable iron, nickel alloy, high strength bronze, hardened steel, magnesium alloy, reinforced plastics, and nickel. The straight-cylindrical shank seats in standard drill chucks on drill presses, CNC machining centers, and hand-held power drills. This is a Series 1290 bit manufactured to ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra length at 12 inches OAL with a 9-inch flute for deep-hole reach\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across a broad range of metalworking materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tapered web reduces entry thrust\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.1563 inches diameter fits standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral design promotes chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows for straightforward resharpening in the field\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drill chucks accepting a straight-cylindrical shank.

Ensure the drill chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Due to the extended length of this bit, use the lowest practical spindle speed and apply steady, controlled feed pressure to minimize deflection and bit breakage. Always wear appropriate eye protection when drilling metal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1290\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\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: 5999924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692523553074,"sku":"5999924","price":46.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df1c74c5de9b95e50bb2af0d0c73fcfd_b6ea6060-26d7-4224-870c-7d7eac5a85ee.jpg?v=1788298864","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999924-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
