The 1\/8 inch diameter bit features a 135-degree split point for self-centering entry without a center punch, and a parabolic flute geometry that improves chip evacuation at extended depths. At 12 inches overall length with a 9 inch flute length, it reaches into deep bores and recessed cavities that standard-length bits cannot access. The uncoated HSS construction keeps the bit serviceable through multiple sharpenings. Licensed tradespeople and journeymen machinists are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for deep-hole drilling applications across a wide range of workpiece materials including carbon steel, stainless steel, hardened steel, cast iron, aluminum, brass, bronze, magnesium, nickel, thermoplastics, and thermosetting plastics. The QC1290P series is built to ANSI standards and is rated as a high-performance grade bit. Right-hand cutting direction makes it compatible with standard drill press and handheld drill driver setups. Web thinning with a tapered web configuration reduces thrust requirements and improves penetration in harder materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry — no center punch required\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design improves chip clearance during deep drilling passes\u003c\/li\u003e\n  \u003cli\u003e12 inch overall length with 9 inch flute length for deep-reach applications\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction reduces axial thrust in hard materials\u003c\/li\u003e\n  \u003cli\u003eUncoated high speed steel — resharpenable and compatible with standard grinding equipment\u003c\/li\u003e\n  \u003cli\u003eANSI-standard geometry, QC1290P series, high-performance grade designation\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.

Secure the workpiece before drilling and confirm the drill chuck is properly tightened to the 1\/8 inch shank diameter before operation. Reduce feed rate and apply cutting fluid when drilling harder ferrous materials to manage heat buildup at extended lengths. Inspect the bit for wear or damage before each use — a dull or cracked bit should be resharpened or replaced before continuing work.\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: 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\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\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute to Diameter Ratio\u003c\/strong\u003e: 10xD\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: 5996453\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51710346297650,"sku":"5996453","price":57.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/335feb05ca6eae9af4b3a42d71353bfe_997dcab4-4781-4ed1-8561-c97b97ebbac6.jpg?v=1788465934","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996453-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
