Built to Series QC91P standards, it features a 135-degree split point that reduces walking and improves self-centering on entry without a center punch. The parabolic flute geometry accelerates chip evacuation and allows faster feed rates compared to standard twist flutes. At 0.1910 inches in diameter (wire size 11) with a 3.625-inch flute length and 6-inch overall length, this bit suits through-hole drilling in medium to thick stock where a jobber-length bit would fall short. Machinists, maintenance mechanics, and fabricators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for general-purpose and heavy-duty drilling in a wide range of materials including alloy steel, carbon steel, hardened steel, tempered steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, copper, graphite, magnesium, magnesium alloy, nickel, titanium, and titanium alloy. The taper length body is particularly useful in production environments where deeper hole reach is needed without stepping up to a longer extension setup. The straight shank mounts directly in standard drill chucks or collet systems without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile promotes fast chip evacuation and cleaner holes at higher feed rates\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness and heat resistance for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eTaper length body (6 inches OAL, 3.625-inch flute) reaches deeper than standard jobber bits of the same diameter\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows easy visual inspection of wear and edge condition\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; rated heavy-duty grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose taper length drill bit for use in standard drill chucks and collet holders accepting a 0.1910-inch straight shank.

Ensure the shank is fully seated and the chuck is tightened securely before operation. Power down or de-energize the machine completely before changing or inspecting the bit. Do not exceed the recommended spindle speed for the material being drilled, and apply cutting fluid when drilling hardened steel, stainless steel, or titanium to extend tool life.\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: 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1910 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\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: 3.625 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: 6 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: 0.1910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eThreaded Shank\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\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: 5997966\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693199622450,"sku":"5997966","price":34.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_98831412-31c0-4718-b9a5-5e2a7fa88244.jpg?v=1788308832","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997966-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
