Built from high speed steel with a bright\/uncoated finish, it features a 135-degree split point that reduces walking and requires no center punch on most surfaces. The parabolic flute geometry accelerates chip evacuation and allows deeper cuts with less feed force. At wire size 50 (0.0700 inches decimal), this bit suits fine-diameter drilling tasks where accuracy and clean entry are critical. Machinists, tool-and-die technicians, and maintenance professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling alloy steel, carbon steel, stainless steel, cast iron, aluminum, aluminum alloy, brass, bronze, copper, magnesium, magnesium alloy, malleable iron, nickel, tempered steel, hardened steel, titanium, titanium alloy, and graphite. Its parabolic flute and web-thinned construction make it effective in both general-purpose production drilling and self-centering applications where hole placement tolerance is tight. Straight shank design fits standard drill chucks without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirements on most workpieces\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry improves chip flow and reduces heat buildup during deep cuts\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration lowers cutting resistance for heavy-duty use\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and toughness across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard Jacobs-style and keyless drill chucks without a reducer\u003c\/li\u003e\n  \u003cli\u003eANSI-standard geometry ensures dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style taper length drill bit compatible with standard straight-shank drill chucks in bench drills, drill presses, CNC machining centers, and handheld power drills.

Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life, even though this bit does not have through-coolant capability. Follow applicable machine shop safety practices and disconnect power before changing bits in any stationary equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0700 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0700 inches\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\/Finish\u003c\/strong\u003e: Bright\/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\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy-Duty Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5997159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699924992306,"sku":"5997159","price":23.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_47cc6207-f825-4775-bd2e-d8360a436ea5.jpg?v=1788383555","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997159-taper-length-drill-bit-50","provider":"Voomi Supply","version":"1.0","type":"link"}
