Designed for drilling deep holes that standard-length bits cannot reach, it features a 9-inch spiral flute length and a 118-degree standard point angle with web thinning for easier penetration and reduced thrust. The straight-cylindrical shank and right-hand cutting direction make it compatible with conventional drill presses, mills, and hand-held drilling equipment. This is a general-purpose bit suited to trade and industrial shops where extended reach and accurate hole sizing are required.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for use on a broad range of workpiece materials including aluminum, magnesium, copper, nickel, titanium, and synthetic materials as primary applications. Secondary materials include stainless steel, hardened steel, nickel alloys, malleable iron, high-strength bronze, magnesium alloys, and reinforced plastics. The Series 1290 designation places it within a recognized extra-length line intended for production and maintenance environments where deep hole drilling is a routine task. Machinists, tool-and-die technicians, and maintenance professionals will find this bit suited to demanding applications that require both reach and cutting stability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.3438-inch diameter with 12-inch overall length for deep-hole reach\u003c\/li\u003e\n  \u003cli\u003e9-inch spiral flute length provides extended chip evacuation path\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning reduces entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with bright uncoated finish for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with regular spiral for balanced cutting performance\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant, Series 1290 extra-length designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank drill chucks on drill presses, milling machines, and compatible hand-held equipment.

Use appropriate cutting fluid for the workpiece material to extend tool life and manage heat buildup. Reduce feed pressure when breaking through the exit side to prevent bit deflection or workpiece damage. Inspect the cutting edges and web area before each use and replace the bit if chipping or wear is evident.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.3438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\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: 0.3437 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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\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\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: 6000186\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51706537902386,"sku":"6000186","price":61.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8cf06bd8daf32e394895c2bdc60c8b9.jpg?v=1788435283","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000186-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
