Ground to a 135-degree split point with a parabolic flute profile, it penetrates faster than standard jobber bits and requires no center punch to start. At 6 inches overall length with a 3-5\/8-inch flute length, the extended reach suits deeper bores where a standard-length bit falls short. Right-hand cut, straight shank, and a web-thinned tapered web complete the geometry. This is a general-purpose heavy-duty bit suited for machinists, pipefitters, millwrights, and maintenance tradespeople who drill through varied stock daily.\u003c\/p\u003e\n\u003cp\u003eWire size No. 5 at 0.2055 inches diameter places this bit in the range commonly used for tap drilling, close-tolerance hole sizing, and through-hole work in structural and fabricated assemblies. The QC91P series is rated for use in alloy steel, carbon steel, stainless steel, hardened steel, tempered steel, cast iron, malleable iron, brass, bronze, copper, aluminum, aluminum alloy, magnesium, magnesium alloy, nickel, titanium, titanium alloy, and graphite. It is self-centering at the point, reducing layout time in production and field environments alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point starts on contact without center punching\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry clears chips aggressively in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust and extends bit life in tough alloys\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach for deep or obstructed bores\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with bright\/uncoated finish for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for dimensional accuracy and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, magnesium, magnesium alloy, malleable iron, nickel, stainless steel, steel, tempered steel, titanium, and titanium alloy.

Power down or de-energize the drill press or hand drill before bit changes. Use cutting fluid appropriate to the workpiece material when drilling stainless, titanium, or hardened alloys to extend tool life and reduce heat buildup. Do not exceed the drill press or tool manufacturer's recommended spindle speed for the bit diameter and material being cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2055 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-5\/8 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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2055 inches\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\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91P\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: 0.042 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: 5997154\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693113868594,"sku":"5997154","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_81e15ccf-e97e-4269-931a-4abef142a99d.jpg?v=1788307499","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997154-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
