Part of the QC1290P series, it features a 135-degree split point for self-centering entry and a parabolic flute profile that promotes aggressive chip evacuation and reduced heat buildup. With a 12 inch overall length and a 9 inch flute length, this bit reaches deep into workpieces where standard-length drills fall short. It is uncoated HSS, ground to ANSI standards, and rated as a high-performance grade. Machinists, tool and die technicians, and maintenance mechanics reach for this bit when depth and chip clearance are the primary concerns.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for a wide range of ferrous and non-ferrous materials in both shop and field applications. The split-point tip eliminates the need for a center punch on most materials, and the web-thinned, tapered web configuration reduces thrust and improves penetration efficiency. Right-hand cutting direction with a straight cylindrical shank fits standard three-jaw chucks and collet systems without adapter hardware. Typical applications include structural fabrication, HVAC ductwork penetrations, electrical conduit routing, plumbing rough-in, and general metalworking where deep reach is required in a single pass.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering starts without a center punch\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003e12 inch overall length with 9 inch flute length for deep-reach drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting thrust and extends bit life\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction, uncoated, compatible with a broad material range\u003c\/li\u003e\n  \u003cli\u003eANSI-standard ground, high-performance grade for production and heavy maintenance use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible workpiece materials include aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, graphite, hardened steel, magnesium, magnesium alloy, malleable iron, nickel, stainless steel, steel, structural steel, tempered steel, thermoplastics, and thermosetting plastics.

Use appropriate cutting fluid or lubricant when drilling ferrous metals or stainless steel to control heat and extend cutting edge life. Peck drilling in stages is recommended for deep holes to clear chips and prevent bit deflection. Disconnect power to any power tool before changing or inspecting drill bits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\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: 0.25 inches (1\/4 inch)\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: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split-Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\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: Uncoated\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 10xD\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: QC1290P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 5996417\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722916528434,"sku":"5996417","price":70.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/335feb05ca6eae9af4b3a42d71353bfe_23407cc7-5f7c-4138-aa5e-ea15e40cea79.jpg?v=1788597848","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996417-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
