With a 1\/8 inch diameter, a 12 inch overall length, and a 9 inch flute length, this bit reaches into recessed locations that standard-length drill bits cannot access. The 118-degree standard point angle and web-thinned tip reduce entry force and improve centering on flat or curved surfaces. The bright uncoated finish makes wear easy to monitor. Right-hand spiral flutes clear chips efficiently during continuous cuts. Licensed machinists, pipefitters, HVAC technicians, and general mechanical trades rely on extra length bits like this when drilling through deep stock, structural members, or stacked materials.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for general purpose drilling in both production and field environments. Primary workpiece materials include aluminum, magnesium, copper, nickel, synthetic materials, and titanium. It also handles secondary materials such as stainless steel, hardened steel, high strength bronze, nickel alloy, malleable iron, reinforced plastics, and magnesium alloys. The straight cylindrical shank fits standard three-jaw drill chucks without adapters. The Series 1290 designation indicates a standard extra length geometry manufactured to ANSI specification. This bit is well suited for HVAC equipment frames, electrical enclosure drilling, plumbing rough-in through deep framing members, and similar trade applications where reach is the limiting factor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12 inch overall length and 9 inch flute length for deep-reach drilling\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch diameter with straight cylindrical 1\/8 inch shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip for reduced thrust and accurate starts\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a broad range of ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral with 2 flutes promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows visual inspection of cutting edge condition\u003c\/li\u003e\n  \u003cli\u003eManufactured to ANSI standards under Series 1290 general purpose classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general purpose extra length drill bit compatible with any standard drill chuck accepting a 1\/8 inch straight cylindrical shank, including corded and cordless drills, drill presses, and magnetic base drills used across HVAC, plumbing, electrical, and mechanical service trades.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eEnsure the workpiece is firmly secured before drilling to prevent bit deflection at this extended length. Use the lowest practical RPM for steel and harder alloys to manage heat buildup, and apply cutting fluid when drilling ferrous materials for extended bit life. Inspect the cutting edges before each use — high speed steel bits will show visible dulling or bluing if overheated. Follow applicable OSHA and shop safety requirements for rotating tool use, including proper chuck key removal before powering on.\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\/8 inch (0.1250 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: 1\/8 inch (0.1250 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\u003eSeries\u003c\/strong\u003e: 1290\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\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: 6000178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691650810162,"sku":"6000178","price":43.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8467264dcd869cccdfe2bf30515ae04.jpg?v=1788288046","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000178-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
